Miniature stepper motor

With a good power-to-volume ratio, 6 mm outer diameter, 9.3 mm length and weighing 1.4 g, the ADM 0620 is claimed to be the smallest two-phase miniature stepper motor in the world.

The motor is designed for voltages between 3 and 6 (voltage regulated). The angular acceleration reaches 165,000 rad/s, which means that a power ring between 125 and 250 mW can be achieved depending on the operating mode.

The motors have a sintered bearing in the standard configuration but are also available with ball bearings. The operation temperature range is -40 to 70°C. Various controllers are available for the motor and special controllers can be developed to match any system.

The modular complement, the 06/1 planetary gearhead, is also 6 mm in diameter. The precision gearhead has a steel geartrain and is made for operating temperatures up to 100°C.

Available reduction ratios are from 4:1 up to 4096:1, providing a torque up to 25 mNm.
