Abstract
Official abstract text for this publication.
A motor part of a fuel pump is a brushless motor having a stator and a rotor. The stator has a core, a coil set and an insulator, which holds the core and the coil set in an insulated manner. The coil set has a plurality of coils wound about a tooth part and a plurality of crossing wires connecting the coils. The insulator is formed by stacking central ring parts of a plurality of stator units in an axial direction. At least one of crossing wire holder parts is formed of a combination of guide projections, which are formed on the different central ring parts. The length of the brushless motor in the axial direction can thus be shortened.
First claim
Opening claim text (preview).
What is claimed is: 1. A brushless motor comprising: a stator including a core formed with a plurality of tooth parts arranged in a circumferential direction, a coil set wound on the core, and an insulator holding the core and the coil set while providing insulation therebetween, the stator generating a rotating magnetic field in response to supply of current to the coil set; and a rotor including magnetic poles, which oppose the stator in a radial direction from an inside of th…
