Abstract

PURPOSE:To maintain terminal voltage at a fixed value for the stabilization of characteristic on heavy load, by adjusting the field current of a synchronous motor according to deviation between magnetic flux command and actual values. CONSTITUTION:The synchronous motor 4 is driven by using a power rectifier 1 and power inverter 3. Then, the speed command of an operation command circuit 22 is compared with the actual speed from a speed detector 7 to control the ignition phase of the thyristor of the power rectifier 1. Besides, the output of a magnetic-sensitive element 23 detecting magnetic flux is compared with flux command value of a command circuit 22 to control the power inverter 3 further to compare the output and flux command value of the magnetic-sensitive element 23 by a deviation amplifier 26 for the control of the power rectifier 20 connected to the field winding 5 with the adjustment of field current. Therefore, terminal voltage is proportional to magnetic flux so as to be maintained at a fixed value by controlling magnetic flux with the generation of a fixed output regardless of load.
