1.2 Description
The NorthStar WIND56 is a modular digital encoder. This magnetoresistive encoder sensor-based unit has
been designed for fast, easy mounting onto a standard NEMA 56C motor face. The basic design philoso-
phy is as follows: The encoder frame is mounted onto the C-face flange of a motor. This positions the
sensor and contains the electronics. The magnetic pulse wheel on the motor shaft has magnetic pulses
imprinted on its outside surface. As the motor spins, the passing magnetic pulses actuate the
magnetoresistive sensor. The resulting electronic signals are processed into square wave signals by the
internal electronics.
