Nema 34 (86mm) High Torque Hybrid Stepper Motors

The FL86STH series stepper motors are high torque, size Nema 34, 1.8 degree hybrid stepper motors with a holding torque up to 12Nm.

A high torque stepping motor output more torque than standard hybrid stepping motors due to the use of powerful rare earth magnets instead of the traditional permanent magnets. The motors are 1.8 degrees-per-step have single or double shaft and the option of optical encoder and planetary gearbox available for most motors.
