Miniature motor

The ADM 0620 is a miniature two-phase stepper motor with a 6 mm outer diameter, is 9.3 mm long, weighs 1.4 g and provides a high power-to-volume ratio.

The motor is designed for voltages between 3 and 6 V (regulated). The inertial moment of the rotor is a minimal 0.7 x 10^-9 kgm² and the angular acceleration reaches 165,000 rad/s, providing a power rating between 125 and 250 mW depending on the operating mode.

The motor has a sintered bearing in the standard configuration but is also available with ball bearings. It can operate in temperatures between -40 and +70°C.

Various controllers are available for the motor and customised controllers can be developed on request.

The modular 06/1 planetary gearhead is also 6 mm in diameter. The precision gearhead has a steel geartrain and is suitable for operating temperatures up to 100°C. Available reduction ratios are from 4:1 to 4096:1, providing a torque up to 35 mNm.

Areas of application include precision medical instruments, optical instrumentation, security and inspection systems and microactuators.
