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 JP7336329
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 rotation detecting magnet 21 which is rotatably supported by the rotational axis 11; strain parts 22a and 22b which are provided in an outer peripheral side in a radial direction of the rotation detecting magnet 21 and in which a strain occurs according to a magnetic pole change due to rotation of the rotation detecting magnet 21; and a strain sensor 23a which is provided in the strain part 22a and outputs a strain signal according to a strain of the strain part 22a, and a strain sensor 23b which is provided in the strain part 22b and outputs a strain signal according to a strain of the strain part 22b.SELECTED DRAWING: Figure 1
