ABSTRACT:
An encoder system with a timing disc includes a preassembled circuit board with a U-shaped sensor/emitter embracing the edge of the timing disc. The timing disc is configured to be slipped onto a motor shaft at the flange end of an electric motor, and the circuit board is designed to be mounted on the flange of the motor by mechanical, thermal, and/or adhesive means of attachment. The motor flange is equipped with a centering collar that has a flattened portion on its otherwise circular circumference. The circuit board has a cutout opening that receives the centering collar in a form-fitting way when the circuit board is slid onto the flange of the motor. By rotating the circuit board 90° about the centering collar, the circuit board is secured in a defined position on the motor flange.
