Document Type and Number:
Japanese Patent JP7344064
Kind Code:
B2
Abstract:
To provide a motor including 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 211 which is rotatably supported by the rotational axis 11; a plurality of fixed magnets 212 which are provided at positions at which they are separated from each other in a circumferential direction of the rotational axis 11 and react to a magnetic pole and magnetic force changing according to a rotation position of the rotation detecting magnet 211; a plurality of strain parts 22 which are provided corresponding to the plurality of fixed magnets 212 and in which a strain occurs according to reaction of the fixed magnets 212; and a plurality of strain sensors 23a and 23b which respectively output strain signals according to strains of the plurality of strain parts 22.SELECTED DRAWING: Figure 1
