Document Type and Number:
Japanese Patent JPH06165454
Kind Code:
A
Abstract:
PURPOSE: To make unnecessary the slip rings and brush sliding parts for connection with external resistors and smaller, and facilitate maintenance.
CONSTITUTION: External resistors 23, 24, and 25 are mounted on a rotor shaft 10. A function of the conventional cam controller is replaced with a semiconductor switching element 2 mounted on the rotary shaft and a control circuit 30.
