Motor

Abstract

The invention discloses a motor which comprises a stator iron core. The stator iron core comprises a plurality of T-shaped parts, pole shoes, inclined parts, insulators and a stator winding, wherein the T-shaped parts protrude from a basal part towards a center direction along the radial direction and are formed in the circumference direction, and the pole shoes are formed by extending the end parts of the T-shaped parts from the circumference direction towards both sides; each inclined part at the tail end of each pole shoe is formed by the gradual reduction of an inner peripheral surface of each pole shoe towards the end part of each T-shaped part; each insulator covers each T-shaped part, at least part of each inclined part and at least part of the basal part; and the stator winding is wound on the T-shaped parts covered by the insulators and is insulated from the stator iron core. The motor maximizes the winding area of a stator wound on the stator iron core and keeps the inner peripheral surfaces of the pole shoes in an insulation distance from the stator winding by insulated protrusions so as to reduce the insulation thickness of the insulators and save the material cost.

Description

technical field [0001] The invention relates to a motor, in particular to a motor which maximizes the winding area of ​​the stator winding on the stator core and ensures the insulation distance. Background technique [0002] Generally, a brushless DC (BLDC) motor refers to a motor that replaces the rectification function that was originally performed mechanically by brushes and commutators with semiconductor relays. [0003] The above-mentioned motor includes a stator fixedly arranged inside the housing, and a rotor arranged inside the stator at a certain interval and rotated by interacting with the stator. [0004] The above-mentioned rotor includes a rotor core formed by stacking a plurality of silicon steel sheets, a rotating shaft pressed into the center of the rotor core, and a structure in which different magnetic poles are alternately arranged along the circumferential direction of the rotor core. Multiple magnets around the rotor core. [0005] figure 1 It is a sc...
