Title:
CONCENTRIC CONTROLLER FOR NON-COAXIAL INDUCTION MOTOR
Document Type and Number:
Japanese Patent JP3176578
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concentric controller for a non-coaxial induction motor which allows the structure to be simplified, thereby allowing reduction in the manufacturing cost and which can increase reliability in control.
SOLUTION: A concentric controller for a non-coaxial induction motor is provided with a sensor 55 for detecting the eccentricity of a rotating body 50, an arithmetic section 56 for calculating quantity of current in a rotating body, so as to correct the eccentricity based on the detection result of the sensor 55, and a drive circuit 53 so structured as to control the quantity of current in the rotating body 50. Also included in this controller are central controlling means 1, 2 which are structured so as to apply an electromagnetic force crossing at right angles to the center of the rotary shaft of the rotating body 50 toward the center of the rotating body 50.
