Problems solved by technology

However, since in the motor the base plate is positioned opposite the sensor magnet in the lateral direction of the motor, the size of that part of the base plate instead results in an increase in the size of the motor in the lateral direction.

[0046] Hereinafter, a concrete embodiment of the present disclosure will be described with reference to the drawings.

[0047] like figure 1 As shown in , the motor 1 in this embodiment is used as a drive source for a power window device that electrically raises and lowers a window glass of a vehicle. The motor 1 has: a motor part 2, such as figure 1 Shown in the upper part; deceleration part 3, which is set on the output side of the motor part 2, that is to say, set in such as figure 1 shown below; and the connector module 4, which is installed on the side of the deceleration part 3, that is, installed in such as figure 1 place shown on the left. In general, the motor 1 has a flat shape, and a direction ( figure 1 In the direction perpendicular to the paper surface) the thickness is thinner. Here, the flat direction refers to the longitudinal direction of the motor when the motor 1 is seen from the axial direction, that is, as figure 1 The left-right direction in herein...

Abstract

An object of the present invention is to provide a motor capable of suppressing enlargement. The axial direction of the worm wheel (49) is used as the horizontal direction of the motor of the motor (1), and the plane perpendicular to the horizontal direction of the motor is used as the flat surface of the motor (1). Let the first end of the sensor magnet (17) in the transverse direction of the motor be in contact with the imaginary plane parallel to the flat surface as the first imaginary plane (P1), and put the second end in contact with the sensor magnet (17) in the transverse direction of the motor , and the imaginary plane parallel to the flat plane is taken as the second imaginary plane (P2). A rotation detection element (62) for detecting the rotation of the rotation shaft (13) of the motor (1) is arranged on the control circuit board (61). The control circuit board (61) is provided parallel to the flat surface or inclined relative to the flat surface, and is provided between the first imaginary plane (P1) and the second imaginary plane (P2).

Description

technical field [0001] The present invention relates to a motor as a drive source used, for example, in a power window device of a vehicle. Background technique [0002] International Publication No. WO03 / 71073 discloses a motor including: a motor unit having a rotating shaft; a decelerating unit that decelerates and outputs the rotation of the rotating shaft assembled at the output-side end of the motor unit; A sensor magnet that rotates integrally with the rotary shaft; and a connector block that electrically connects the motor unit to the outside. The reduction unit has: a worm shaft disposed coaxially with the rotation shaft and rotatable integrally with the rotation shaft; and a reduction mechanism constituted by a worm wheel meshing with the worm shaft. The gear housing is assembled to the motor unit. The reduction mechanism is housed in the gear case, and a connector block is provided. The connector module includes: a connector portion electrically connected to the...
