PK Series Stepping Motors

The high-torque type motor adopts a new technology and design. A high-torque motor produces approximately 1.2 ~ 1.5 times higher torque than a conventional stepping motor of the same size.

This motor combines high torque and a compact size. Five frame sizes are available: 0.79 in. (20mm), 1.10 in. (28mm), 1.38 in. (35mm), 1.65 in. (42mm) and 2.22 in. (56.4mm). Each specification provides torque equivalent to a motor of the next larger frame size, supporting high-torque operation even in the high-speed range.

For example, high torque type PK246PB [motor frame size 1.65 in. (42mm)] has the same holding torque as the standard type PK266-01B [motor frame size 2.22 in. (56.4mm)]. This means a smaller size motor will maintain the same torque. This allows for downsized and lightweight equipment.

This motor combines the superior performance of our high torque motor with our latest technology advancements in efficiency to achieve superior overall performance in a stepping motor. Three stack lengths to choose from in a 1.65 in. (42 mm) frame offer holding torque performance 1.2 ~ 1.5 times greater than a conventional stepping motor.

Utilizing the latest in motor technology, the High-Torque, High-Efficiency type stepping motors are able to achieve a significant reduction in the amount of heat generated from the motor.
