Robot MarketPlace - MMP TM57 12V 7:1 Planetary Gearmotor

Midwest Motion Products makes extremely high quality geared motors, manufactured here in the United States of America. They are robust, reliable, and will outperform almost any other motor we sell.

The TM57 line of motors is made with a precision planetary gearhead and all steel gears. The gearhead is available with ten different gear ratios ranging from 3.7:1 to 308:1. The brushed motor is totally enclosed with no ventilation and uses powerful ferrite magnets to deliver maximum performance while keeping costs resonable. The motor is available in 12V, 24V, and 48V versions, each with identical speed and torque at the motor's nominal voltage. See this chart for a quick comparison of the gear ratios.
