MOTOR SPEED CONTROLLER - MATSUSHITA ELECTRIC IND CO LTD

Title:

MOTOR SPEED CONTROLLER

Document Type and Number:

Japanese Patent JPH04208083

Kind Code:

A

Abstract:

PURPOSE: To relieve restriction of the processing time of the title controller by a method wherein a speed detecting means which performs a plurality of detections for one turn of a motor, a compensating means which generates control signals with a first processing means and a second processing means, etc., are provided and the first processing means and the second processing means are operated in parallel with each other.

CONSTITUTION: A DC motor 1 drives a rotary sensor 2 and a load 14 directly to rotate. A speed detecting means 3 which performs a plurality of detections for one turn of the motor 1 with an AC signal from the rotary sensor 2, a compensating means 4 which generates control signals with a first processing means 8 and a second processing means 9 and a driving means 13 which drives the motor 1 in accordance with the control signals from the compensating means 4 are provided. The first processing means 8 and the second processing means 9 are operated practically in parallel with each other. In other words, the processings from the detecting operation of the speed detecting means 3 to the control signal generation of the control signal generating means are shared by the first processing means 8 and the second processing means 9 and the respective processing means are operated in parallel with each other with predetermined timings. With this constitution, the processing time can be reduced.
