The 10-mm diameter motor is 24-mm long and combines an ironless rotor with Neodymium rare-earth magnets for a stall torque of 2.89 mNm with speeds up to 14,700 rpm. Precious metal commutation provides low contact resistance for low starting voltages. Planetary and spur gearboxes are available in both 10 and 12-mm diameters for an output torque up to 450 mNm. A two-channel magnetic encoder is also available.
