摘要： An object of the present invention is to provide a brushless motor and a wiper apparatus which allow high-precision control of a motor unit, and which can be reduced in size and weight. The first surface (91) of the control board (90) is provided on the same side as the rotating shaft (46) and the output shaft (51) so as to face the sensor magnet (MG1), the first and second Hall ICs (94a) and (94b) are mounted on the first surface (91). The second surface (92) of the control board (90) is provided on the opposite side from the first surface (91), and the third Hall IC (94c) is mounted on the second surface (92), and located between the first and second Hall ICs (94a) and (94b) so as to face the sensor magnet (MG1). In addition, the MR sensor (95) is mounted on the first surface (91) so as to face the second sensor magnet (MG2).

摘要： A thermally-conductive member (60) is provided between a housing (53) and a FET module (54f) constituting a controller (54b), and used to release heat of the FET module (54f) to the housing (53). Therefore, heat of the FET module (54f) can be dissipated to outside via the thermally-conductive member (60) and the housing (53). Since the housing (53) is made of aluminum, a surface area of the housing (53) can be increased to become larger than the conventional cooling fin member, and heat of the FET module (54f) can be dissipated to outside, the DR-side wiper motor (21) can be reduced in size and improved in cooling efficiency. Furthermore, since a cooling fin member is not inserted in the case cover (54) in a conventional manner. Therefore, the case cover (54) can be molded with ease, and the wiper motor can be improved in assembly workability.
摘要翻译：导热构件（60）设置在构成控制器（54b）的外壳（53）和FET模块（54f）之间，用于将FET模块（54f）的热量释放到壳体（53）。因此，FET模块（54f）的热量可以经由导热构件（60）和壳体（53）散发到外部。由于壳体（53）由铝构成，壳体（53）的表面积可以增加到比现有的冷却翅片构件大，并且FET模块（54f）的热量可以散发到外部，DR 侧刮水器马达（21）的尺寸可以减小并且提高冷却效率。此外，由于冷却翅片构件没有以常规方式插入到壳体盖54中。因此，可以容易地模制壳体盖（54），并且可以提高刮水器马达的组装操作性。
