This is a NEMA 34 bipolar hybrid stepper motor with a holding torque of 46 kg-cm. It is a brushless DC motor that runs in an open-loop control system. The input pulse decides the rotation angle.
It delivers 46 kg-cm of torque at 4 A per phase. It responds well to starting, stopping and reversing pulses from a stepper motor driver. It is built for the high torque demands of large machines and can run at high speeds.
Typical uses include large CNC mills, lathes and routers, large 3D printers, robotics and automation systems. Resonances can occur if the motor is installed improperly.
