Compare speed and torque with sourced 10 mm ratings. Verify the exact motor curve.
Enter positive speed and torque values, then run the screen. The result is a first check, not a motor selection or thermal guarantee.
Confirm body length, shaft, connector, mounting fit, and the space needed for the driver. Two motors with a 10 mm outside diameter can have very different packages.
The cited 10 mm examples list nominal continuous torque from 1.57 to 1.85 mNm. Treat those as model ratings, not a universal limit for every 10 mm motor.
Continuous operation depends on winding losses, ambient temperature, duty cycle, and the heat path into the mounting structure. Use the selected motor’s thermal data.
These are named product configurations, not a market-wide range. Their ratings use different windings and thermal assumptions, so do not combine the highest speed from one row with the highest torque from another as a guaranteed operating point.
| Reference configuration | Nominal torque at speed | Maximum speed | Housing-to-ambient thermal resistance |
|---|---|---|---|
| FAULHABER 1028 S 006 B · 6 VØ10 × 28.1 mm · digital Hall sensors | 1.68 mNm @ 25,660 rpm | 79,000 rpm | 42.4 K/W |
| FAULHABER 1028 S 012 B · 12 VØ10 × 28.1 mm · digital Hall sensors | 1.57 mNm @ 26,800 rpm | 79,000 rpm | 42.4 K/W |
| maxon ECX SPEED 10 M · 18 VØ10 × 25.1 mm · Hall-sensor configuration | 1.85 mNm @ 53,400 rpm | 65,000 rpm | 39.8 K/W |
FAULHABER values are from its Series 1028 B datasheet (edition 25 April 2025; rated values at 22°C). The maxon values are from the selected ECX SPEED 10 M 18 V configuration. Sources reviewed 6 October 2026; check the current datasheet and operating curve before design approval.
A motor can meet a speed limit and a torque limit separately while still missing the combined target. Check the selected winding’s curve, the heat path, and the drive electronics as one system.
A torque–speed pair is valid only if it falls inside the selected motor’s curve under the stated cooling and supply conditions.
Plot continuous and peak shaft torque at the required speed for the selected winding and voltage. Confirm peak duration and acceleration separately.
Account for ambient temperature, enclosure, mounting material, duty cycle, and the manufacturer’s winding and housing thermal resistances.
Match supply voltage, phase-current limit, commutation method, and Hall or encoder signals to the motor and controller.
The calculator uses mechanical output power = torque × angular speed. Winding heat is a separate loss term; it cannot be inferred from shaft output power without efficiency/current and thermal data.
Sending the whole operating context makes a supplier review more useful than asking for a “10 mm motor” by diameter alone.
Maximum body diameter and length, shaft diameter and length, mounting details, connector space, and allowable tolerances.
Required speed and torque at the shaft, continuous versus peak duration, acceleration, starts per hour, and load inertia.
Available voltage, driver type and phase-current limit, plus sensorless, Hall, or encoder feedback needs.
Ambient temperature, enclosure and mounting material, expected operating hours, and acceptable maintenance interval.
Send the target speed, torque, duty cycle, mounting, and driver details for an OEM operating-point discussion.
Suppliers may describe brushless motors with an ironless winding as coreless or slotless. Confirm the construction in the exact model data sheet because terminology varies by manufacturer.
It depends on the model and installation. The cited examples list 1.57–1.85 mNm nominal continuous torque at their stated operating points; their curves and thermal conditions differ.
No. Maximum speed is a model rating, not a guarantee of continuous operation at every torque. Use the manufacturer’s operating curve and lifetime guidance for the chosen load and mounting.
Yes. Both reference families offer Hall-sensor configurations. Confirm the sensor signals, wiring, controller support, and package length for the selected version.
No. It calculates mechanical shaft output and screens against published example values. It does not calculate winding losses, temperature rise, duty-cycle heating, or the combined speed–torque curve.
A gearbox can trade speed and efficiency for higher output torque, but the ratio, gearhead diameter, length, backlash, and efficiency must fit the application. Compare a larger motor if the added length or losses are unacceptable.
No. Winding voltage affects the speed–torque curve and current. Match the selected winding to the supply and controller, then verify the operating point on that winding’s data.
