Midwest Motion Releases New Gearmotor

March 15, 2007
Midwest Motion Products announced the release of a new DC Gear Motor, the Model No. MMP-TM55-90-12V GPk52-124. Accepting any 12 Volt DC source, including battery power, this robust gear motor measures just 2.14" in diameter, by 7.7" long, and has a keyed output shaft of 12 mm diameter by 25 mm long. Easy mounting is accomplished with four "face mount" M5 threaded holes, equally spaced on a 40mm Diameter bolt circle. The output of this reversible gearmotor is rated for 124 in-lbs continuous torque, at 3.2 RPM, and 178 in.lbs. peak. Despite its size and weight of less than seven lbs., the gearmotor requires just 1.0 Amp at 12 volts DC to generate its full load torque. Motor windings for 24, 36 & 90 volts are available. This design is rated at an IP 54 protection level for operation in harsh environments. Typical options available from the company include servo motors with integral optical encoders, failsafe brakes, analog tachometers, and planetary gearheads, with standard ratios ranging from 3:1 to 2653:1, and standard or low backlash precision gearing available.
