Title:
ROTATING SPEED CONTROLLER OF MOTOR DRIVEN FACILITY
Document Type and Number:
Japanese Patent JPS6149693
Kind Code:
A
Abstract:
PURPOSE:To efficiently and reliably operate with an inexpensive facility investment by controlling the rotating speed of a load by a variable speed power source in a low speed rotating range, while operating at a constant speed by a commerical power source in a high speed rotating range, and controlling the slip of a joint by joint control means. CONSTITUTION:A fluid joint 14 is operated in a nonslip state by joint control means in a low speed rotating range to control the rotating speed of a load by a variable voltage variable frequency power source 18, while a drive motor 12 is operated at a constant speed by a commercial power source 16 in a high speed rotating range, and the rotating speed of the load is controlled by controlling the slip of the joint by joint control means. In order to control it, a sequence logic circuit 34 is provided. Thus, an efficient and reliable operation can be performed with an inexpensive facility investment. Since the joint having slip characteristic is interposed, the torque ripple of the drive motor is not transmitted to the load.
