To satisfy the demands of todays drive technology, much use is made of converter circuits with adjustablefrequencies for controlling a.c. motors. When it is necessary to change the speed, or as a result of braking in the drive train, the motorҒs frequency is greater than the output frequency of the frequency converter. In this case, the motor works as a generator and supplies energy that in most cases is converted into heat via a braking resistor.The way the braking resistor works is determined by the operational condition of the motor. As a rule, thebraking resistor is only switched on...
