Two-Phase Stepper Motor

Aug. 19, 2004
Joining the company's ARSAPE product line is the ADM 0620 stepper motor.


Joining the company's ARSAPE product line is the ADM 0620 stepper motor. Its 6-mm outer diameter, 9.3-mm length, and 1.4-gm weight make it the smallest, produced in series, two-phase stepper motor in the world, according to the company. Designed for voltages between 3 and 6 V, the ADM 0620's inertial rotor moment is 0.7 10- 9 kg-m2 and angular acceleration reaches 165,000 rad/sec for a power rating of 125 to 250 mW. Operating temperature is 40 to 70°C. The standard motors have a sintered bearing, but ball bearings are also available. Applications include precision medical instruments, optical instrumentation, security and inspection systems, microactuators, and those where size, cost, and reliability are important.
