    • A motor control apparatus to supply current from a D-C source to an electric motor has a thyristor chopper circuit, the duty factor of which is controlled depending on a current instruction signal. The thyristor chopper circuit is provided between the terminals of the D-C source in series with an electric motor, and has main and auxiliary thyristors. A series connection of a capacitor and a reactor, forming commutating elements, is connected across the auxiliary thyristor and oscillates to generate a pulse of current through a forward diode in order to turn off the main thyristor when the auxiliary thyristor is turned on. In addition, a saturable current transformer having first, second and third windings is provided. Through the first winding chopper current flows, and the second winding operates as the reactance of the commutating elements. The third winding is provided within the closed circuit formed when the chopper circuit is blocked, and causes current across the secondary winding to charge the capacitor of said chopper circuit.

    • A thyristor chopper whose gate signal is controlled by a magnetic phase shifter is connected between a battery and a series motor of an electric vehicle and is short-circuited by a bypass contactor as soon as the duty factor of the chopper attains 100%. In the short-circuited condition of the chopper, the magnetic phase shifter remains idle and does not participate in the control operation although the instruction current and the actual motor current are kept applied to its control windings. Therefore, the level of the output from the magnetic phase shifter is indicative of the value of the actual motor current when the instruction current value is fixed, so that the actual motor current value can be detected by detecting the output level from the magnetic phase shifter. When the actual motor current value is detected to be excessively large, the bypass contactor short-circuiting the chopper is released to decrease the value of the motor current, while when the actual motor current value is detected to be excessively small, a field-weakening contactor is closed to connect a field-weakening resistor in parallel with the field winding of the series motor so as to accelerate the motor by the field-weakening control.
    • 其栅极信号由磁性移相器控制的晶闸管斩波器连接在电动车辆的电池和串联电动机之间,一旦斩波器的占空因数达到100%,就被旁路接触器短路。 在斩波器的短路状态下,尽管指令电流和实际电动机电流保持施加在其控制绕组上,磁性相移器保持空闲并且不参与控制操作。 因此,当指令电流值固定时,来自磁相移器的输出电平表示实际电动机电流的值,从而可以通过检测来自磁相移器的输出电平来检测实际的电动机电流值 。 检测到实际的电动机电流值过大时,释放旁路接触器短路斩波器以降低电动机电流的值,而当实际的电动机电流值被检测到过小时,磁场弱化 接触器闭合以将串联电动机的励磁绕组并联的弱磁电阻连接,以通过弱磁控制来加速电动机。

    • An electric vehicle control device is disclosed which includes a main circuit for supplying power from a d.c. power supply to a driving motor through a chopper, a phase shifter for controlling the conduction ratio of the chopper in such a manner that a current flowing through the driving motor is proportional to an instruction value determined by how much an accelerator pedal is trodden, a circuit for instructing a regenerative braking operation, and a changeover switch for changing over the main circuit between a power running state and a regenerative braking state. The changeover switch is changed over in the regenerative braking state when another power running state in the direction opposite to the current running direction is instructed in a predetermined time after the stop of a power running state where the chopper had a conduction ratio greater than a preset value.

    • In an electric car, wherein the powering drive and the braking drive are executed by on-off controlling a current through a d. c. motor by means of a chopper, when the electric car is below a predetermined speed, a field coil of the d. c. motor is put into a series winding connection so as to carry out full field control, and when the car is above the predetermined speed, the field coil of the d. c. motor is changed-over to a shunt winding connection so as to carry out weak field control.The duty cycle of the chopper is controlled with the running state of the electric car taken into consideration in order that the field current at the time when the series winding connection has been changed-over to the shunt winding connection may become substantially equal to a value before the change-over, whereby the transient change of the current between before and after the change-over of the field coil is suppressed.
