MicroMo Electronics, Inc. announces the expansion of its miniature stepper motor product line with the addition of its Series ADM1220. The miniature stepper motor has an external motor-diameter of only 12 mm and a length of 17.2 mm. The ADM1220 has a holding torque without current of 2.4 mNm and can achieve a high boost torque of 4.1 mNm. The ADM1220 offers 20 full steps per revolution in full step mode and is capable of microstep operation at speeds ranging from 10 rpm to 6000 rpm. . The ADM1220S is capable of 160 microsteps per revolution with a maximum error of +/- 0.2º.The miniature stepper motor is very rugged with a strong 1.5mm diameter output shaft and large bearings. The ADM1220 has no axial endplay meaning that rotational audible noise is lessened.
The Series ADM1220 can be combined with a gearhead and/or lead screw for a complete miniature stepper motor drive system or linear actuator. The planetary, spur, and zero-backlash gearheads are available in both 10 and 12 mm diameter with various reduction ratios allowing a continuous torque up to 300 mNm. Stable low-outgassing lubricants are a particularly attractive for optical, space, military, photonic, and telecommunication applications. Precision ball bearings for the motor are optional.
Series ADM1220 motors with 3 and 6 volt windings are immediately available from stock with a 24 - 48 hour turnaround.
