Title:
MOTOR HAVING A PLURALITY OF SERIES FIELD WINDINGS
Document Type and Number:
Japanese Patent JPH07123668
Kind Code:
A
Abstract:
PURPOSE: To provide a DC motor which can avoid degradation of efficiency caused by the change of the revolution of an armature. CONSTITUTION: This main series field winding S101 and auxiliary series field winding S102 of a series or compound motor are connected to each other on an armature A101 side. A main power supply CPS101 and a 1st diode CR101, which is electrically continuous in the direction of the power supply side of the auxiliary series field winding S102, are connected to the power supply side of the main series field winding S101. An auxiliary power supply CPS102 is connected through a 2nd diode CR102 which is connected so as to be electrically continuous in the direction of the auxiliary series field winding S102.
