摘要： A drive system comprises first and second motors for driving an electric car in response to alternating electric currents supplied to their coils. The first and second motors have their respective first and second rotors assembled on a common shaft at angular positions which are shifted by a first predetermined angle in their direction of rotation. Moreover, the first and second motors are energized by currents which are shifted in phase by a second predetermined angle. The first and second predetermined angles are individually determined in advance on the basis of the undesirable torque-fluctuation harmonic and the polar ratio of the motor. As a result, the torque fluctuations of the selected harmonic of the motor frequency of the first and second motors can offset each other to reduce the vibrations due to resonances.

摘要： A motor for an electromobile includes a rotor having permanent magnets and a stator coil for generating an output torque when fed with a motor current. A rotor position detector or resolver is connected to the spindle of the rotor for detecting the magnetic position of the rotor in terms of a voltage waveform and a motor controller controls the output current to the motor on the basis of the magnetic position signal coming from the rotor position detector. A first malfunction detecting circuit detects any malfunction of the rotor position detector in response to an abnormal voltage waveform coming from the rotor position detector. A second disconnection detecting circuit detects a disconnection of the motor controller from the invertor which develops drive current for the motor. A control unit outputs a signal to the motor controller for stopping the motor in response to a signal from either the first malfunction detecting circuit or the second disconnection detecting circuit.
