The PHB57K series stepper motors offer a very high value for a standard round-frame stepper motor. The PHB57K series step motors have low rotor inertia which allows them to accelerate fast and offer high torque. With the highest possible torque up to 110 N.cm, operational characteristics with regard to vibrations, noise and microstep resolution are improved at the same time. The PHB57K series stepping motors are terminated with 4 or 6 or 8 wire leads, and easily connected in bipolar or unipolar way.
