Abstract

PURPOSE:To prevent the vibration of a speed controlling system due to pulsating voltage by a slot component of a speed detecting generator by mounting a filter decreasing the pulsating voltage by the slot component of the speed detecting generator at a preceding stage of a function generator. CONSTITUTION:Deviation signals between speed signals outputted from the speed detecting generator 17 directly coupled with a lifting motor 12 and speed command signals 1 are added to the field function generator 3 and the armature function generator 4 through a torque command generator 2 and the filter constituted by a resistor 60 and a capacitor 50. The field function generator 3 and the armature function generator 4 each output a field current command and an armature current command corresponding to a torque command. Accordingly, since the pulsating voltage by the slot component of the speed detecting generator is decreased, the vibration of the speed controlling system due to the pulsating voltage is prevented, and motor speed can be controlled stably.
