Planetary Gear Motors

Compare PG planetary gearboxes paired with DC motors, from the compact PG16-DC050 to the larger PG56-DC997.

PLANETARY GEAR MOTORS

These combinations pair a DC motor with an inline planetary gearbox. They are useful when the load requires a slower shaft speed than the motor supplies and the mechanism benefits from an output on the motor axis.

The listed combinations run from PG16-DC050 to PG56-DC997. Ratio and motor winding change the reference output speed and torque; the calculated motor rated-point torque can exceed the gearbox limit, so compare it with the maximum continuous torque of the selected gearbox rather than treating it as an allowable load.

For a suitable combination, review:

Motor voltage and selected winding
Output speed at the required load and reduction ratio
Gearbox continuous torque and application peak loads
Gearbox diameter, assembly clearance and output shaft interface

Open the series for individual combinations. Gearbox losses, duty cycle and the actual load affect the final operating point.
