The PHB42W series stepper motors are 0.9 degree/step, featuring higher precision and lower torque than the PHB42S series stepper motors. With the highest possible torque up to 42 N.cm and also compact size (42 x 42 mm), the PHB42W step motors offer high resolution and are employed with economically priced drives for precision applications. The PHB42W series stepping motors are terminated with 4 or 6 wire leads, and easily connected in bipolar or unipolar way.
