This big size 57mm NEMA 23 stepper motor has a good holding torque 2.0Nm/284oz.in with rated current 4.2A, integrated with a 24V electromagnetic brake. The brake will pause the motor shaft rotation in a very short time while the brake power is off. Frankhumotor's brake motors are absolutely an ideal solution for the machines that require frequently work and stop under vertical operation.
