The 10,000-rpm motors achieve a constant torque of 3 mNm. The rotor revolves in an axially aligned neodymium magnetic field without cogging or iron loss. Precious-metal commutation creates low-transition resistances letting the motor operate with low starting voltages suitable for battery-operated portable devices.
