Title:
電気機械装置及び電気機械装置の停止制御方法
Document Type and Number:
Japanese Patent JP6425350
Kind Code:
B2
Abstract:
An electromechanical apparatus (100) includes: a motor (130) that includes a rotation shaft (132) and that applies to the rotation shaft (132) a torque in a direction toward an angular position in accordance with control; a rotation sensor (134) detecting an angular position of the rotation shaft (132); and a motor control unit (181) controlling rotation of the rotation shaft by switching an angular position to which the rotation shaft (132) rotates in accordance with an angular position detected by the rotation sensor (134). The motor control unit (181), in a case where the rotation shaft (132) is to be stopped, after applying a torque in a direction toward an angular position of a stop position target to the rotation shaft (132) and when the angular position detected by the rotation sensor (134) exceeds an angular position of the stop position target by a predetermined amount, moves the angular position of the stop position target to an angular position between the angular position of the stop position target and the angular position detected by the rotation sensor (134).
