Abstract
The utility model relates to a driving controller for elevator, which comprises a phase lock circuit connected with a floor switch button, a carriage elevating location switch and an allocating switch for the opening and closing of carriage door; a frequency conversion transfer drive control device connected with the phase lock circuit; and a transfer device connected between the frequency conversion transfer drive control device and the host electrical motor and the door electrical motor. According to the floor switch button, a phase lock signal is generated by the phase lock circuit and then sent to the frequency conversion transfer drive control device. According to the phase lock signal, the frequency conversion transfer drive control device generates a pulse length modulating signal to control the transfer device. As different pulse length modulating signals are generated by the carriage elevating location switch and the allocating switch for the opening and closing of carriage door in different times, the transfer device transfers these pulse length modulating signals to drive the host electrical motor and the door electrical motor.
