Oriental Motor: Stepper Motors (PKP Series)

Spur (SH) Geared Type Stepper Motors

The Spur (SH) Geared type stepper motor is our basic gear type which provides high speed with high permissible torque.

Our new SH geared type is now paired with our PKP High-Torque stepping motors offering more electrical configurations, higher permissible speed, backlash specifications and a machined face for improved mounting precision. These new SH geared types are available in frame sizes 28 mm (1.10 in.), 42 mm (1.65 in.) and 60 mm (2.36 in.). Motor connection cable is included (-L type).

For traditional SH geared or encoder options, we continue to offer our Standard SH geared type 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.

Features of the Traditional SH Geared Type:

SH geared type stepper motors with high permissible torque offer the full benefit of the speed reducing capability of geared motors, delivering high resolution, high torque and smooth low-speed rotation. The Spur (SH) Geared type can easily satisfy the requirements of various kinds of low-speed positioning applications.

Smooth Rotation at Low Speeds
Use of a geared type stepper motor allows for an increase in the speed of the motor which results in a smoother motion while maintaining the low output speed required by the application.

Six Gear Ratios
SH geared motors are available with six different gear ratios: 3.6:1, 7.2:1, 9:1, 10:1, 18:1, and 36:1.

Ideal for High Inertia Drive
The stepper motor itself can drive an inertia of 10 times the rotor inertia. The geared type can reduce the load inertia by the square of the gear ratio. Therefore, the geared type is suitable for driving larger inertial loads.
