摘要： A device for detecting asynchronization or stepping out of a stepping motor without making the stepping motor large in size. Parallel resonance circuit LC is provided in a recovery circuit of stator coil RL of the stepping motor for detecting linking current IX. If the stepping motor is out of step, the magnetic resistance between stator and rotor increases while the reactance of stator coil RL decreases. When motor drive current ID is turned off, a large transient current is momentarily generated yet is quickly dampened. While the motor drive current ID is off, linking current IX approaches zero. Consequently, if the stepping motor is out of step, there is no substantial difference in the linking current IX when motor drive current ID is turned on from when motor drive current ID was off. Also, the amplitude of the transient or resonance waveform is smaller than the amplitude when the stepping motor is operating normally. By thus detecting the resonance waveform of the parallel resonance circuit when motor drive current ID is turned on, it can be precisely determined whether or not the stepping motor is out of step.

摘要翻译： 用于检测步进电机的异步或步进电机而不使步进电机尺寸变大的装置。 并联谐振电路LC设置在用于检测连接电流IX的步进电机的定子线圈RL的恢复电路中。 如果步进电机失步，则定子和转子之间的磁阻增加，同时定子线圈RL的电抗减小。 当电机驱动电流ID关闭时，瞬间产生大的瞬变电流，并迅速衰减。 当电机驱动电流ID关闭时，连接电流IX接近零。 因此，如果步进电机失步，电机驱动电流ID从电动机驱动电流ID关闭时电机驱动电流ID开启时，连接电流IX没有实质差异。 此外，瞬态或共振波形的振幅小于步进电机正常工作时的振幅。 通过在马达驱动电流ID接通时检测并联谐振电路的谐振波形，可以精确地确定步进电机是否失步。

摘要： There is an electric power steering apparatus comprising: an electronic control circuit to output a drive signal having a vehicle velocity response characteristic and steering response characteristic in accordance with the vehicle velocity, steering torque, and steering direction; and a motor for assisting a steering force which is made operative by the drive signal. The electronic control circuit has a braking control circuit to short-circuit between both terminals of the motor when the steering operation is stopped and the supply of the drive signal to the motor is stopped while the vehicle is running at a high speed. With this apparatus, when the steering operation is suddenly stopped when the vehicle is running at a high speed, the inertia rotation of the motor can be rapidly reduced. The yawing of the vehicle body due to the inertia rotation can be effectively prevented.
