Oriental Motor: Stepper Motors (PK Series)

Planetary (PN) Geared Type Stepper Motor

The Planetary (PN) Geared type stepper motor provides high speed (low gear ratios), high accuracy positioning and high permissible/maximum torque. Available in gear ratios from 5:1 up to 50:1.

Planetary (PN) Geared Type

The PN gear employs a planetary gear speed-reduction mechanism. The PN gear achieves the specified backlash of three arc minutes through the improved accuracy of its components and the backlash-elimination mechanism. That mechanism is comprised of two sets of internal and planetary gears on the upper and lower levels with the internal gears and planetary gears reduce clockwise backlash; the lower-level internal gears and planetary gears reduce counterclockwise backlash.

The PN gear mechanism is comprised primarily of a sun gear, planetary gears and an internal tooth gear. The sun gear is installed on the central axis surrounded by planetary gears enclosed in an internal tooth gear centered on the central axis
