Sensorless Speed Control of Slip-Ring AC Motor Based on Rotor Voltage Frequency Estimation

Sensorless speed control system with slip-ring AC motor is a highly developed, wellproven system for heavy duty tasks especially in the field of industrial cranes and another heavy duty material handling systems. In situations where there is no tachometer or incremental encoder as a speed feedback devices, actual speed information is realized via rotor voltage frequency estimation (RVFE). Using line frequency as a reference, the fundamental component of the rotor frequency gives the slip of the motor, which determines the speed in digital form.
