Tool layer: quick sizing input
Enter boundary-safe values first. Invalid input is blocked and recoverable.
Boundary: 6V to 24V. 12V systems usually screen best around 11V to 13.2V after supply-drop checks.
Boundary: 300 to 12,000 rpm. Typical 12V high-speed actuator screening window is 2,200 to 4,500 rpm.
Boundary: 5 to 400 mNm.
Boundary: 5% to 100%.
If the result is inconclusive, use the design-review CTA instead of forcing a procurement choice.

Audit-first enhancement: each high-impact content gap is tracked with explicit remediation status.
Gap closure ledger
Blocker/high gaps are closed in-page; unresolved items remain explicitly marked for follow-up.
| Gap found | Decision impact | Stage1b action | Status |
|---|---|---|---|
| Keyword implied "high speed actuator" but previous drafts did not expose a measurable speed-force tradeoff gate. | High risk of selecting "high speed" SKUs that collapse force under load and fail cycle-time targets. | Added source-backed speed-force matrix and rule-based conditional/not-recommended outputs. | Closed in stage1b enhancement (2026-04-29) |
| Tool output lacked duty-cycle thermal interpretation for actuator use. | High risk of approving 70%+ duty requests on hardware classes commonly specified around intermittent duty. | Added duty and environment penalties, boundary notes, and explicit fallback CTA actions. | Closed in stage1b enhancement (2026-04-29) |
| High-speed wording was not tied to screw pitch / ratio implications. | High risk of treating motor rpm as linear-speed guarantee without conversion and efficiency losses. | Added lead-screw conversion method rows and ratio sanity-check narrative in result interpretation. | Closed in stage1b enhancement (2026-04-29) |
| Driver selection copy mixed startup peaks with continuous operation decisions. | Medium-to-high risk of selecting H-bridge by headline peak current only. | Added explicit decision gates for continuous current, startup surge, and VM window alignment. | Closed in stage1b enhancement (2026-04-29) |
| Lifecycle and endurance data was overgeneralized across vendors. | Medium risk of overconfident production assumptions from pre-RFQ screening output. | Moved lifecycle/endurance claims to pending-evidence ledger with required supplier artifacts. | Closed with explicit pending block (2026-04-29) |

Methods and evidence
Transparent formulas, dated sources, and explicit known/unknown boundaries.
Method flow
Input to estimate to boundary check to action path.
| Method block | Formula / rule | Decision value |
|---|---|---|
| Mechanical shaft power estimate | P_shaft = 2 * pi * n / 60 * T | Converts screw-side rpm and torque targets into shaft mechanical load envelope. |
| Lead-screw thrust conversion | T ~= F * Lead / (2 * pi * eta_screw) | Maps target linear force into required shaft torque using screw lead and efficiency assumptions. |
| Electrical current estimate | I_run ~= P_shaft / (V * eta_sys) + I_idle | Adds drivetrain and driver efficiency losses to avoid optimistic current budgeting. |
| Startup surge estimate | I_start ~= 2.1 to 2.8 * I_run | Represents actuator startup and reversal spikes for VM and current-headroom checks. |
| Linear speed conversion | v_linear ~= n * Lead / 60 | Ties motor/screw rpm to cycle-time impact so "high-speed" claims remain measurable. |
| Confidence score | Base 92 - boundary penalties + matched-window bonus | Penalizes high-duty/high-torque/high-temp combinations and rewards realistic 12V actuator windows. |

Only net-new, source-verifiable information is included here. Each row states scope and decision consequence.
New evidence-backed decision facts
Update date: 2026-04-29. Facts without stable public evidence stay in the pending block.
| Topic | New fact | Applicable condition | Decision effect | Certainty |
|---|---|---|---|---|
| Speed-force inversion at 12V | Actuonix L16 12V entries show higher force options with much lower speed than the 22N high-speed point. | Applies when teams read "high speed" without checking force and duty constraints together. | Treat speed and force as a coupled gate; no single 12V value should be interpreted as universally high-speed. | Known with vendor scope |
| Duty-cycle gate | Thomson training defines duty cycle as on-time percentage, with 25% represented as 15s on / 45s off in a 60-second cycle. | Applies to repetitive motion workloads where average thermal load dominates lifecycle outcomes. | Flag >=70% duty as conditional by default unless verified by supplier endurance curves. | Known |
| Lead-screw conversion discipline | Lead-screw design references explicitly convert linear load and lead into torque demand with efficiency terms. | Applies when actuator selection starts from linear force targets but catalog data is motor-side torque/speed. | Always convert force->torque before RFQ; avoid rpm-only screening. | Known |
| 12V driver headroom | DRV8876 class supports 4.5V-37V and lists 3.5A peak-current framing. | Applies to 12V actuator projects needing headroom beyond 10.8V-class bridges. | Prefer 12V-capable bridge classes for high-speed actuator startup transients and reversal events. | Known |
| Low-voltage bridge boundary | DRV8833 class is bounded at 2.7V-10.8V VM. | Applies when BOM candidates from low-voltage ecosystems are reused in 12V actuator programs. | Treat >10.8V rails as not recommended on this class without architectural changes. | Known |
| Ratio-driven speed spread | Pololu 37D 12V tables include both 1000 rpm and low-rpm variants within one family. | Applies when teams assume frame-size continuity equals speed continuity. | Bind ratio, torque, and duty in one gate review instead of selecting by frame label. | Known with vendor scope |
| Continuous current interpretation | Pololu guidance notes continuous operation is often safer around <=25% stall-current range for brushed gearmotors. | Vendor-specific heuristic, not a universal law for every motor class. | Use as screening risk-weight only; enforce PN-level thermal tests before lock-in. | Known with vendor scope |
| Direct-drive ceiling context | maxon RE16 publishes high mechanical-speed envelopes that exceed many actuator screw-output needs. | Applies when comparing direct-drive + external transmission against integrated geared actuators. | Use direct-drive for speed headroom only if conversion hardware and control bandwidth are budgeted. | Known with product-family scope |
| Compliance baseline | RoHS Annex II concentration thresholds remain a hard documentation gate for covered markets. | Applies to any 12V actuator assembly entering RoHS-scoped supply chains. | Require supplier declarations before production RFQ release. | Known |
| Public evidence gap | Cross-vendor lifecycle claims for high-speed actuator duty at matched load are not consistently published. | Applies to final life and maintenance-interval commitments. | Keep lifecycle claims conditional until PN-level endurance reports are collected. | Pending confirmation / no reliable public dataset |
Source-backed benchmark points
Cross-check points use published numbers instead of assumptions, and include a decision-use note so data can drive action.
| Evidence point | Architecture role | Published data | Decision use |
|---|---|---|---|
| Actuonix L16 (12V rows) | Integrated micro linear actuator reference | 12V examples include ~32 mm/s @ 22N and slower travel at higher force points. | Shows high-speed and high-force are inversely coupled in compact actuator classes. |
| Pololu 37D 12V category table | Geared rotary drive reference | One 12V family spans roughly 1000 rpm to 30 rpm options by ratio choice. | Prevents ratio-blind selection and supports architecture branching early in RFQ. |
| TI DRV8876 / DRV8833 | Bridge-selection boundary comparator | DRV8876: 4.5V-37V vs DRV8833: 2.7V-10.8V. | Converts voltage-window data into immediate driver shortlist/exclusion rules for 12V projects. |
| maxon RE16 speed envelope | Direct-drive speed ceiling reference | Mechanical speed boundary reported at 16,000 rpm class. | Shows direct-drive speed margin exists but still needs transmission and control design to become actuator motion. |
Decision gates with measurable pass/fail checks
Convert source claims into gates that can be verified in bench, compliance, and shipping workflows.
| Gate | Threshold | Required action if not met |
|---|---|---|
| Rail/driver voltage gate | Bridge operating window must cover the full rail and transient profile (e.g., DRV8876 4.5V-37V; DRV8833 capped at 10.8V). | If rail exceeds bridge window, move to a qualified driver class before motor/prototype release. |
| Duty-cycle thermal gate | Treat >=70% commanded duty as conditional unless supplier publishes matching endurance conditions. | Request thermal rise and lifetime evidence; otherwise derate duty or change actuator class. |
| Startup current gate | Use modeled startup envelope around 2.1x-2.8x run current and verify against bridge, supply, and wiring limits. | If startup exceeds safe headroom, redesign ratio/load profile or power path before RFQ. |
| Speed-force realism gate | High-speed claim must be checked at required force, not at no-load headline values. | Request force-vs-speed curve for target stroke/load and reject one-point marketing claims. |
| Force-to-torque conversion gate | Linear force requirements must be converted through lead and efficiency assumptions before shortlist decisions. | If conversion is missing, block procurement decisions and run conversion worksheet first. |
| Compliance documentation gate | RoHS/REACH declarations and material-disclosure package must exist for selected PN. | If declarations are missing, keep decision status conditional and do not release PO. |
Pending confirmation / no reliable public data
Evidence is insufficient for strong conclusions in these areas.
| Open question | Why evidence is insufficient | Decision impact |
|---|---|---|
| Cross-vendor endurance curves for >=70% duty at matched force/speed points. | Public datasets are inconsistent in test profile, ambient conditions, and failure criteria. | Lifetime recommendations remain conditional until supplier-specific reports are provided. |
| Backlash growth distribution after long-cycle operation on compact lead-screw modules. | Most public material is marketing-level and lacks cycle-count traceability. | Precision-positioning claims require supplier PPAP/validation data before release. |
| Acoustic profile under reversal-heavy motion at high duty. | Comparable cross-vendor noise methodology is rarely published for this class. | Noise-sensitive applications need in-house or supplier lab measurements before sign-off. |
Alternative comparison
Use reproducible dimensions (voltage, torque, response, cost, fit) instead of generic claims.
Option comparison table
If a value is unavailable in your project context, keep it as N/A and request supplier evidence.
| Option | Voltage band | Torque band | Dynamic response | Cost class | Best-fit scenario | Boundary / counterexample |
|---|---|---|---|---|---|---|
| 12V integrated brushed lead-screw actuator | 12V nominal (commonly 9V-14V system rails) | Medium shaft torque via internal reduction | Moderate | Low to medium | Fastest path for compact high-speed push/pull tasks with moderate force targets. | High force usually reduces travel speed sharply; high-duty thermal limits must be validated. |
| 12V DC gearmotor + external lead screw | 12V nominal, broad ratio options | Medium to high (ratio-dependent) | Moderate to slow | Medium | Useful when mechanical integration needs custom stroke or anti-backlash geometry. | More parts and tolerance stack-up; packaging and assembly complexity increase. |
| 12V BLDC + encoder actuator path | Typically 12V-24V systems | Medium to high with controlled profile | High (control-dependent) | Medium to high | Best for high-speed positioning with closed-loop motion quality targets. | Higher BOM and firmware complexity; requires controls validation bandwidth. |
| Solenoid / voice-coil + mechanism alternative | Application-specific | N/A (non-rotary primary drive) | Very high | Medium to high | Good for short-stroke rapid actuation when continuous screw travel is unnecessary. | Stroke and holding-force characteristics differ; unsuitable for long-travel screw requirements. |
Risk and mitigation
Covers misuse risk, cost risk, and scenario mismatch risk with direct mitigation actions.
Risk matrix
| Risk | Impact | Probability | Mitigation path |
|---|---|---|---|
| Assuming headline high-speed value also applies at required force and stroke. | High | Medium-high | Demand force-vs-speed curves at your load window and run cycle-time simulation before RFQ. |
| Selecting H-bridge by peak current headline only. | High | Medium | Check continuous-current thermals, VM window, and startup/reversal waveform margins together. |
| Approving high-duty profile without endurance evidence. | High | Medium | Gate decisions with duty-cycle endurance reports and staged thermal validation on samples. |
| Skipping force-to-torque conversion and screening by rpm text only. | High | Medium-high | Run lead/efficiency conversion worksheet and confirm torque reserve before shortlist freeze. |
| Treating this screening tool as release-grade qualification. | Medium-high | Medium | Use tool output for pre-RFQ triage only; require PN-level validation and compliance documents before PO. |
Scenario examples
Each scenario includes assumptions, modeled output, and the minimum next action.
Scenario table
| Scenario | Assumption | Estimated result | Action |
|---|---|---|---|
| Compact valve actuator, speed-first | 12V rail, 3200 rpm screw speed target, 85 mNm, 35% duty | Recommended with 12V bridge headroom and moderate thermal risk. | Request two ratio variants and compare loaded linear speed across full stroke. |
| Packaging gate, high force + high speed request | 12V rail, 4500 rpm target, 260 mNm, 65% duty in warm enclosure | Conditional; speed-force inversion and thermal duty margins are critical. | Split into two candidate architectures: high-speed moderate-force vs lower-speed high-force. |
| Industrial mini actuator, near-continuous duty | 12V rail, 2800 rpm target, 220 mNm, 85% duty | Not recommended for compact brushed paths without major derating. | Move to heavier actuator class or BLDC closed-loop path and request endurance data first. |
| Direct-drive experiment with external screw | 12V rail, 9000 rpm motor-side target, 45 mNm, 20% duty | Conditional direct-drive path; high-speed available but integration complexity rises. | Validate conversion hardware, backlash, and control loop before committing to this path. |
