MOTOR CONTROLLER, MOTOR ACTUATOR, AND MOTOR ACTUATOR FOR AIR-CONDITIONING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a motor controller that can highly reliably detect the rotational position of a motor based on the counted result of commutating surges, and to provide a motor actuator and a motor actuator for air- conditioning equipment.;SOLUTION: An output gear 34 which is rotated by means of the driving force of the motor 20 is provided with a pulse plate 66 having a projecting section 76 protruded from the outer peripheral section of the plate 66. When the gear 34 reaches a prescribed rotational position, pickups 68 and 74 are conducted through the pulse plate 66 and projecting section 76. The motor controller 10 discriminates whether or not the commutating surge corresponding to the rotational position of an output shaft 36 is counted when the pickups 68 and 74 are conducted and, when the surge corresponding to the rotational position is not counted, corrects the counted value of commutating surges to the corresponding count number. Therefore, the error caused by a count error, etc., can be eliminated and the reliability of the controller 10 is improved.;COPYRIGHT: (C)2003,JPO
