stepper motor with a D-type shaft and 30.61 kg-cm holding torque. It is designed for CNC machines and other motion-control equipment that requires higher torque than a typical NEMA 17 stepper motor. The motor operates at 4 A per phase and uses open-loop positioning control driven by input pulses.\u003c\/p\u003e\u003cp\u003eEach input pulse determines the motor's rotation angle, while pulse frequency controls speed.
