The PHB20Y series stepper motor are the miniature stepper motors, offering a holding torque up to 2.4N.cm in a compact size. Unlike DC motors, the PHB20Y series stepper motors already have a very high torque at low speed and often gears are not required which leads to considerably more economical drive solutions. The PHB20Y series step motors are terminated with 4 wire leads, and connected in the bipolar way.
