モータ、モータの製造方法及び処理装置
Document Type and Number:
Japanese Patent JP6848705
Kind Code:
B2
Abstract:
To provide a motor which enables improvement of detection accuracy of a rotation angle, and to provide a motor manufacturing method and a processing device.SOLUTION: A motor includes: a motor part having a stator and a rotor which can rotate relative to the stator; a stator housing to which the stator is attached; a hollow rotor housing to which the rotor is attached; a bearing which supports the rotor housing so that the rotor housing can rotate relative to the stator housing; and an angle detection part which detects a rotation angle of the rotor housing relative to the stator housing. The angle detection part has: a magnetized body which is attached to an end part of the rotor housing in a direction of rotation axis of the rotor housing; and a magnetic sensor which is attached to the stator housing and detects magnetism of the magnetized body. The magnetic sensor is disposed at a position facing the magnetized body.SELECTED DRAWING: Figure 1
