Method for measuring absolute position of rotor in motor servo system

The invention discloses a method for measuring the absolute position of a rotor in a motor servo system, comprising the steps of: integrally combining the motor and a position sensor; and by utilizing position information provided by a predetermined position as well as relative position information and pitch information provided by the sensor, and recombining the position information through using a proper method so as to obtain absolute position information of the motor rotor. According to the method, a zero position indicator is not required; after outage, the absolute position of a zero position of a relative system of the motor rotor can be obtained through the predetermined position of the motor rotor; compared with a coarse / fine coupling double-speed rotary transformer system, the high-precision absolute position information is obtained by using the simple and reliable sensor, so that the structure of the integrated high-performance servo motor is simplified and decreased, then the structure is more compact and the volume is decreased; and at the same time, a signal processing circuit and coarse / fine coupling operation are decreased, so that compared with the coarse / fine coupling double-speed rotary transformer system, the performance-price ratio is improved and the complexity level is reduced.
