  • Page 17: Speed Detection Board

    Speed Detection Board On a small board, which is attached underneath the motor, the circuits for speed detection and signal shaping are arranged. The motor speed is optically detected by an infra-red light barrier. The motor axle has a hole at the same level as the light barrier. This effects that the light beam will be interrupted twice during one motor revolution.
