Abstract
An aligning and protective apparatus for a stepping motor which includes a sensor housing having first and second sensor pairs located therein. An aligning cover has a receiving area therein to receive the sensor housing. The first and second sensor pairs are placed apart a predetermined distance in the housing which is positioned on the motor to coact with a timing disk used in controlling the operation of the stepping motor. The cover with the sensor pairs therein is rotated on the motor until the sensor pairs are properly located on the motor to effect the desired lead angle for the motor. The cover is also shaped to protect the sensor pairs and the timing disk from dust.
