The PHB28Y series stepper motors are bigger than the PHB20Y series stepping motors, offering a holding torque up to 10.0N.cm. The standardized shaft diameter of 5 mm makes it possible to install a cost-effective encoder in the double shaft version in order to monitor the rotation. The PHB28Y series stepping motors are terminated with 4 wire leads, and connected in the bipolar way.
