Oriental Motor: Stepper Motors with Planetary Gear (PK Series)

Planetary (PS/PL) Geared Type Stepper Motor

The Planetary (PS/PL) Geared type stepper motor provides high speed (low gear ratios) and high permissible/maximum torque. Available in gear ratios from 5:1 up to 36:1 [1.65 in. (42 mm) and 2.36 in. (60mm) only].

The Planetary Geared motor is available in 1.10 in. (28 mm), 1.65 in. (42 mm), 2.36 in. (60 mm) and 3.54 in. (90 mm) frame sizes.

High Permissible Torque

In conventional spur-gear speed reduction mechanisms, gears mesh one to one, so the amount of torque is limited by the strength of each single gear. On the other hand, in the planetary gear speed reduction mechanism, a greater amount of torque can be transmitted, since torque is distributed through dispersion via several planetary gears.

Encoder Option Available

The PK Series stepper motor with encoder offers high torque and precise feedback capability.
