39 Series Hybrid Stepper Motor

Overview

The 39 Series Hybrid Stepper Motor is compact two-phase stepper motors designed for equipment requiring controlled rotary motion, reliable positioning, and a compact motor footprint.

With a standard 1.8° step angle, the series provides 200 full steps per revolution for controlled incremental movement. The available models cover different current, phase resistance, inductance, holding torque, motor mass, and motor length requirements, allowing the motor to be selected according to the electrical and mechanical requirements of the application.

The 39 Series features a square 39.2 mm maximum motor frame dimension with a compact body configuration and front mounting arrangement. Its available configurations are suited to equipment where motor size, mounting dimensions, and motion-control requirements need to be considered together.
