| Abstract: | Optical-encoder, which is also called photoelectric angei-position sensor, is the core device in measurement of motor speed and rotor position in drive system. There summarize the operating principle of absolute,incremental and hybrid encoder, introduce the choice principle of optical-encoder model and the measuring method of rotor speed and rotor position. The implementation of measuring method of rotor speed and rotor position in variable frequency speed-regulated system of synchronous motor is also given. |
