Title:
CONTROLLING METHOD FOR SPEED OF MOTOR
Document Type and Number:
Japanese Patent JPS59148588
Kind Code:
A
Abstract:
PURPOSE:To remove the influence of the motion of a support to the speed of a rotor by adding a signal of an angular acceleration detecting means mounted on the support to a controller of a motor supported by the support which varies in the attitude during the operation. CONSTITUTION:A motor 1 is supported to a support 2 which varies in the attitude during the operation, a gate turn OFF thyristor 3 is controlled by a speed set signal A, a speed signal B and a current detection signal E, and the speed of the motor 1 is controlled. Angular acceleration detecting means 8 such as a rotary encoder for detecting the angular acceleration in the plane perpendicular to the axis of the motor 1 is mounted on the support 2, the output is added to a set signal A and a speed signal B, thereby controlling the thyristor 3. Therefore, the influence of the motion of the support 2 to the rotor speed can be accurately removed, thereby obtaining a low speed motor adapted for an acoustic device or the like.
