Gearmotors for battery powered applications
MMP-MGM Series DC gearmotors feature a unique design, ranging in size from 12 to 42mm diameter, and are ideal for battery-powered or other low-voltage DC applications.

The Model M815-BR servo drive is a novel unique velocity loop encoder feedback device.
Servo incorporates encoder feedback onboard
Designed to accept unregulated DC from 20 to 80V DC, the Model M815-BL PWM servo amplifier features a continuous output current of 8A, and a peak of 15A for 1s.
Designed to provide ample torque in a compact and lightweight package, the GM Series features a novel metrically dimensioned, round, face-mounting configuration unlike that of many other gear-motors available.
Because of the planetary gear design, a wide range of ratios can be obtained in single, two and three stage gearbox designs.
The ratio selection begins at 2:1 all the way up to 450:1, to provide for significant speed reduction and greater mechanical (torque) advantage.
Output shaft speeds range from less than 1 to 3000rev/min.
Integrally assembled to compatible brushed DC motors, these units will accept DC input voltages of 12, 24, 36, 48 and 60V DC, and higher.
Current draw is, of course, dependent on the load, however this unique package offers smooth running, quiet DC motors, and planetary gear efficiencies of up to 95% in a single stage unit.
Gear backlash values are available as low as 6arc-min, also in a single stage unit.
The company offers a variety of standard options to accompany the gear-motors, including integrally mounted optical encoders, failsafe brakes, analogue tachometers, and a family of fully compatible single and multi-axis PWM servo amplifiers.
