ABSTRACT:
A motor absolute position signal processing apparatus connected to a signal processor and an optical encoder of a motor control system includes first and second switches, a signal integration amplifier, first and second separators and an inverter. The first switch is connected with the optical encoder, the second switch with the optical encoder and the first switch, the signal integration amplifier with the first and second switches, the first separator with the signal integration amplifier and the signal processor, and the second separator with the signal processor. An input end of the inverter is connected with the second separator and an output end with the second switch. The signal processor outputs an enable signal to be processed by the inverter for switching the first or second switch. The signal integration amplifier processes and transmits two sets of differential signals SIN;/SIN and COS;/COS of the optical encoder to the signal processor.
