70:1 Metal Gearmotor 37Dx54L mm (Helical Pinion)

0104110000066015

New product

This gearmotor is a powerful brushed DC motor with 70:1 metal gearbox intended for operation at 12 V. The gearbox is composed mainly of spur gears, but it features helical gears for the first stage for reduced noise and improved efficiency. These units have a 16 mm-long, 6 mm-diameter D-shaped output shaft. This gearmotor is also available with an integrated encoder.

Key specifications:

voltage no-load performance stall extrapolation
12 V 150 RPM, 150 mA 27 kg⋅cm (380 oz⋅in), 5.5 A

Overview

These powerful brushed DC gearmotors are available in a variety of different gear ratios. Versions with an integrated quadrature encoder are also available, including just the motor and encoder portion by itself (no gearbox).

Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. In order to avoid damaging the gearbox, we recommend keeping continuously applied loads under 10 kg-cm (150 oz-in), and the recommended upper limit for instantaneous torque is 25 kg-cm (350 oz-in). Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC motor operation is 25% or less of the stall current.


These motors are intended for use at 12 V, though in general, these kinds of motors can run at voltages above and below the nominal voltage (they can begin rotating at voltages as low as 1 V). Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.

The gearboxes are composed mainly of spur gears, but they feature helical gears for the first stage for reduced noise and improved efficiency:
