  • Control Of Direct Current Motors (AREA)

Abstract

PURPOSE: To expand the field control range of and reduce the load of the field current regulator of a DC shunt motor by providing switching means directly connected to a power supply via the field current regulator and a controller for turning the switching means on in response to the armature current value.
CONSTITUTION: When a shunt motor is started, a contact 32a is closed to cause the field current to flow through the contact 32a. Accordingly, the motor is started with maximum field strength. When a driver operates an accelerator, a signal is produced from a drive instruction generator 7 to open the contact 32a to thus control the field current by a field controller 10. When the load is increased to cause the armature current to become out of the control range of the field controller, the contact 32a is closed by the signal from a direct-coupling controller 33. When the armature current returns to the control range of the controller 10, the contact 32a is again opened.
