Abstract

The invention specifies position of a lead and ensures axial space. The brushless motor provided by the invention includes a stator 2 provided with a winding 32. The winding 32 coils on a plurality of tooth parts arranged on the inner periphery of an annular stator core 30 in a protruding manner. The brushless motor includes a housing 4 accomodating the stator 3; a lead 6 supplying power to the winding 32 from the external of the housing; and a positioning component 5 supported on at least one part of the housing 4 and the stator 3 in the housing 4 and enabling the lead 6 to extend in the peripheral direction. The positioning component 5 has a specifying part 50 arranged in a space between adjacent windings 32 on the peripheral direction and specifies the position of the lead.

Description

technical field [0001] The present invention relates to a brushless motor equipped with positioning elements for supporting wires within a housing. Background technique [0002] A brushless motor is a motor that obtains output by controlling the energization of the windings of the stator to rotate the rotor, and supplies power to the windings through a power input wire. The wires are connected to the windings of each phase in the casing and are led out to the outside of the casing, and in the case of unconstrained conditions where these wires are not specially supported or fixed in the casing, there is a risk that the wires overlap each other or enter the center of the stator. The problem of assembly is more troublesome due to the space. [0003] In addition, in addition to the wires for power input, there are also wires for sensor signal input and output to control energization inside the case. Therefore, it is necessary to perform assembly work more carefully when these w...
