Title:
MOTOR CONTROLLER
Document Type and Number:
Japanese Patent JP2015033191
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor controller which allows for acceleration up to high speed in feedback control mode, while preventing malfunction.SOLUTION: A motor controller includes a motor having a rotor, and a plurality of position detecting sections for detecting the rotational position of the rotor, and control means for setting a delay angle based on the output from any one of the plurality of position detecting sections. The control means selects any one of the plurality of position detecting sections based on a delay angle change amount, i.e., the difference between a target delay angle and a current delay angle, and sets a delay angle by using the output from a position detecting section thus selected.
