Title:
CONTROLLER FOR MOTOR
Document Type and Number:
Japanese Patent JPS58108995
Kind Code:
A
Abstract:
PURPOSE:To facilitate the adjustment of a motor by commonly using a power source and a speed controller by aiming at the speed characteristic of the motor for performing the field control. CONSTITUTION:Motors 34, 35 are energized in parallel by a common power source 33. A speed controller 32 compares a rotating speed command signal 31 with a feedback signal from a rotating speed detector 36 coupled to the motor 34 to produce a control signal, and feeds it to the power source 33. Accordingly, only the rotating speed of the motor 34 is monitored by the feedback control, and the rotating speed of the motor 35 is not restricted by the controller 32. On the other hand, a field coil 42 is excited by a field power source 40, and is controlled to become the magnetic flux determined by the field magnetic flux command signal 38. This signal 38 is given as the variable signal in response to the rotating speed from a motor torque regulator.
