Stepper Motors

Produced by our Advanced Manufacturing Division, Fraen’s stepper motor utilizes a patented electromagnetic circuit design and is intended for use within an instrument cluster to drive a gage indicator needle.  A two-phase motor with a 90 degree shift between phases, it possesses a permanent magnet in the rotor that features 5 pole pairs around its perimeter, equally spaced at 36 degrees apart.  The motor uses two 6:1 gear reductions to provide a 36:1 reduction from the rotor to the output shaft.
