With an excellent power to volume ratio, 6mm outer diameter, 9.3mm length and weighing only 1.4g, the Arsape ADM 0620 is the smallest two-phase stepper motor in the world.
With an excellent power to volume ratio, 6mm outer diameter, 9.3mm length and weighing only 1.4g, the Arsape ADM 0620 is the smallest two-phase stepper motor in the world.
The motor is designed for voltages between 3 and 6V (voltage regulated).
The inertial moment of the rotor is a minimal 0.7ugm2, and the angular acceleration reaches 165,000rad/s which means that a power rating between 125 and 250mW can be achieved depending on the operating mode.
The motors have sintered bearings in the standard configuration but are also available with ball bearings.
The operating temperature range is from -40 to +70C.
Various controllers are available for the motor, and special controllers can be developed on request to match any system.
The modular complement, the 06/1 planetary gearhead, is also 6mm in diameter.
The precision gearhead has a steel gear-train and is made for operating temperatures up to +100C.
Available reduction ratios are from 4:1 up to 4096:1, providing a torque up to 35mNm.
Areas of application include precision medical instruments, optical instrumentation, security and inspection systems, micro-actuators and any application where the size, cost and reliability play a deciding role.
