摘要： A method of controlling a direct current motor operating in an essentially no torque, discontinuous current mode provides for delivering current pulses to the motor of alternate relative polarity so as to position the motor to rapidly respond to a command signal for torque output. A steering strategy relative to the converters supplying current to the motor prevents a current reversal if the command signal is changing in a direction which would result in increased current to the motor in the direction of the last converter conduction.

摘要： A control apparatus for a thyristor converter which supplies electric power to a load generating a changeable electromotive force, wherein, in response to a load current being changed from an intermittent load current mode to a continuous load current mode, an actual main circuit constant of the load is calculated on the basis of a pregiven main circuit constant of said load, a predetermined minimum value of a DC average motor current at which a compensation control angle is zero, a DC average load current and a set control angle at a time when the load current just changed from the intermittent load current mode to the continuous load current mode.The compensation control angle is obtained on the basis of the calculated actual main circuit constant and the DC average load current.The calculated compensation control angle is added to the set control angle to thereby apply the added angle to the thyristor converter as a firing control angle.

摘要： A motor is controlled by pulse signals applied to the gates of thyristors in a thyristor switching circuit. The speed of the motor is detected by a speed detector, and the instantaneous speed of the motor is calculated on the basis of the current detection speed obtained at the present time and the detected speed obtained at least at one prior point of time. The speed control signal for the motor is calculated on the basis of the deviation between the instantaneous speed and an output signal of a speed directive apparatus. In accordance with the speed control signal, the pulse signals applied to the gates of the thyristors are outputted from a gate pulse generator.

摘要： A floor relay contact 15 is connected between an elevator cage load detecting device 14 and a memory circuit 16. Just before the cage 7 reaches a desired floor the relay contact is closed to apply the output of the load detecting device 14 to a traction motor current control circuit 12 via the memory. This minimizes any acceleration-deceleration bumps and eliminates any vertical gap between the accessed floor sill and the stopped position of the cage when passengers exit before the cage comes to a complete halt.

摘要： In the propulsion system of an electric locomotive, a-c wayside power is converted to direct current for the traction motors by a plurality of phase-controlled rectifying circuits having serially connected outputs. To improve power factor, forced commutation means is provided for turning off the controllable valves in one of the circuits at a desired "extinction angle." This angle is varied with motor speed, but its effective range of variation is restricted so as to avoid undesired leading power factor at low speeds, to optimize power factor when the locomotive is running at full power, and to prevent misoperation when the level of load current is low.
