  • Photoelectric position sensor of step motor
    Patent number: 4088908
    Abstract: In a photoelectric position sensor of a step motor a mirror pyramid is placed across the light beam from a light source and secured on the shaft of the step motor. The faces of the mirror pyramid reflect the light beam to a faceted mirror reflector. The light beam is reflected from a respective facet of the mirror reflector and transferred to a photoelectric receiver by means of light guides. The design of the sensor ensures high resolution and a small moment of load inertia produced by the mirror pyramid on the shaft of the step motor.
