モータ、モータ駆動制御装置及びモータ駆動制御方法
Document Type and Number:
Japanese Patent JP7301698
Kind Code:
B2
Abstract:
To provide a motor including strain sensors capable of detecting operation of a rotational axis.SOLUTION: A motor 1 comprises a motor body 10 which rotates a rotational axis 11, and a sensor unit 20 which detects rotation of the rotational axis 11. The sensor unit 20 comprises: a first magnet 211 which is rotatably supported by the rotational axis 11; a second magnetic 212 which reacts to a magnetic pole and magnetic force changing according to a rotation position of the first magnet 211; a strain part 22 in which a strain occurs according to reaction of the second magnet 212; and a strain sensor 23 which outputs a strain signal according to a strain of the strain part.SELECTED DRAWING: Figure 1
