摘要：in a process for regulating the frequency of a travelling wave motor, a valueproportional to the actual frequency of the alternating voltage excitation of the motor(10) for travelling waves is derived from the amplitude of the alternating voltage (voltagedetection ) detected in the stator (11) of the engine (10) to traveling waves.this value iscompared with a prescribed value according to the prescribed frequency and theexcitation frequency is corrected by adjusting a gap under a proper control algorithm.inorder to maintain the travelling wave motor (10) in a state of stable operation atmaximum power, the prescribed value is derived from the amplitude modulation of thevoltage sensor.this value is obtained by a control circuit in which the voltage issuperimposed, is out, and compared with a prescribed value up to the predeterminedamplitude modulation. the difference detected by the comparator is supplied to aregulator (21) in which the value set is used to output the prescribed value.
