MMP TM57-12V GP52 Brushed Gearmotors

Midwest Motion Products TM57-12 V GP52 combines a 12 V brushed motor with a planetary gearhead. This review compares the 014, 068 and 408 output configurations using their exact manufacturer sheets, including the different full-load speeds, continuous torque, current limits and gearbox losses.
Key Specifications

Review Summary
TM57-12 V GP52 is a candidate for a 12 V mechanism where its loaded output point and brushed-motor service requirements fit the job. The large reduction choices are useful only when the required speed remains achievable. A gearbox torque limit and a duty-dependent motor peak must not be interpreted as extra continuous output capacity.
