    • An elevator capable of supplying electric power to accessory hall devices such as up/down elevator buttons and position indicators without requiring power supply lines between the cage and each hall. A drive battery which supplies electric power to hall devices provided in each hall and a receptor connected to the battery are provided on the hall. A feeder contactable with the respective receptors, a charging device that charges the battery via the feeder and receptor are provided on the top of the cage. When the charging voltage, for example, used in a hall of the floor drops below a predetermined voltage value, the cage stops automatically at the floor and the charger charges the drive battery in the hall of the floor via the receptors and feeder.

    • In order to control a DC motor, a main circuit is constructed in such a manner that a unidirectional thyristor converter is connected to the armature of the motor, while a bilateral thyristor converter is connected to the field system of the motor. Provided is a speed controller which is impressed with a speed command signal and a speed feedback signal so that the speed controller produces an error signal representing the difference between the speed command signal and the speed feedback signal and the error signal is applied to a function generator which in turn produces a field current command signal and an armature current command signal. The field current command signal assumes a value proportional to the error signal when the error signal is less than a predetermined value. The armature current command signal is kept constant when the error signal is below a predetermined value, while it increases, when the error signal exceeds the predetermined value, in proportion to the amount of the excess. These current command signals are used to phase-control the thyristor converters in the field circuit and the armature circuit.
    • 为了控制直流电动机,主电路以单向晶闸管转换器连接到电动机的电枢的方式构成,而双向晶闸管转换器连接到电动机的励磁系统。 提供了速度控制器,其被加速度指令信号和速度反馈信号,使得速度控制器产生表示速度指令信号和速度反馈信号之间的差异的误差信号,并且误差信号被施加到函数发生器 这又产生励磁电流指令信号和电枢电流指令信号。 当误差信号小于预定值时,励磁电流指令信号采取与误差信号成比例的值。 当误差信号低于预定值时,电枢电流指令信号保持恒定,而当误差信号超过预定值时,电枢电流指令信号与超出量成比例地增加。 这些电流指令信号用于对场电路和电枢电路中的晶闸管转换器进行相位控制。
