Problems solved by technology

[0007] However, in the motor described in Patent Document 1, in order to form the joint portion in the motor case, in addition to the power feeding device and the rotation detecting device, an auxiliary connector must be installed in the motor case, and since The installation direction of the rotation detection device on the motor case and the assembly direction of the auxiliary connector on the motor case deviate by 90 degrees, therefore, the assembly workability on the motor case is poor and needs to be improved

Embodiment Construction

[0032] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] The automatic opening and closing type window motor 11 shown in FIG. 1 is a motor used as a driving source of an automatic opening and closing type window device of a vehicle not shown in the figure, and is an electric motor with a so-called speed reducer, that is, a motor that decelerates the The device 13 is installed on the motor body 12 and forms a unit. The control device 14 is provided on the automatic opening and closing type window device, the automatic opening and closing type window motor 11 is connected to the control device 14, and the operation of the automatic opening and closing type window motor 11 is controlled by the driving current supplied from the control device 14. Control is performed so that the window glass is automatically opened and closed.

[0034] The motor body 12 is a so-called DC motor with brushes. A pair of perma...

Abstract

An electric motor in which a power supply device and a rotation detection device that are installed in a motor case are connected to a control device via a connector section. This facilitates assembly of the electric motor. A power window motor has an armature with a rotating shaft and a motor yoke for rotatably receiving the armature. A gear case (24) is fixed to the motor yoke, and a power supply unit (31) for supplying a drive current to the armature is installed in the gear case, in the axial direction of the rotating shaft. A sensor unit (41) for detecting rotation of the rotating shaft is attached to the power supply unit (31), in the axial direction of the rotating shaft. Also, a connector section (61) for connecting the power supply unit (31) and the sensor unit (41) to the control device is formed integral with the power supply unit (31). The sensor unit (41) is first attached to the power supply unit (31) and then the power supply unit (31) is installed in the gear case (24).

Description

technical field [0001] The present invention relates to a motor composed of an armature equipped with a rotating shaft that is freely rotatably accommodated inside a motor casing, and particularly relates to a rotation detection device that detects the rotation of the rotating shaft is installed inside the motor casing of the motor. Background technique [0002] Electric motors are widely used as drive sources for various devices represented by electrical components of automobiles. For example, in an automatic opening and closing window device installed on a vehicle door, etc., a motor equipped with a reducer is fixed inside the door, and the motor operates a regulator to automatically open and close the window glass. [0003] This type of motor has an armature with a rotating shaft and a motor case that accommodates the armature in a rotatable manner, and a power feeding device for supplying a drive current to the armature is mounted inside the motor case. The power feedi...
