Embodiment Construction

[0019] The structure of the electric vehicle motor of the present invention includes a stator and a rotor. The stator is provided with a wire winding, and the lead wire of the wire winding passes through the axle; the rotor is provided with magnetic steel 3 uniformly distributed along its circumference. The polarities of all the ends of the magnetic steels 3 facing the stator are the same, that is, they are all S poles or N poles.

[0020] An annular fixed ring 1 is arranged on the rotor, and the fixed ring 1 is made of iron. The fixed ring 1 and the rotor are connected as a whole with homogeneous materials, and they are actually constituted as a single piece.

[0021] Several protrusions 4 and fixing grooves 2 are arranged on the inner peripheral surface of the fixing ring 1, and the protrusions 4 and the fixing ring 1 are connected as a whole by homogeneous materials. The convex body 4 protrudes inward along the radial direction of the fixed ring 1 , and the fixed groove 2 ...

Abstract

The invention discloses an electric vehicle motor, which is used for solving the problem that the magnetic steel consumption in an existing electric vehicle motor is large and the manufacturing cost is high. The electric vehicle motor comprises a stator and an annular rotor, wherein the rotor is provided with a plurality of magnetic steels, and the stator is provided with wire windings. The electric vehicle motor is characterized in that the rotor is provided with an annularly fixed ring made from a permeability material; the inner circumference of the fixed ring is provided with a plurality of convex bodies and fixed grooves; the convex bodies and the fixed ring which are made from the same material are connected into a whole; the fixed grooves and the convex bodies are arranged at intervals; one magnetic steel is fixedly arranged inside each fixed groove; and the same-side ends of all the magnetic steels are same in polarity.

Description

technical field [0001] The invention relates to an electric vehicle motor, in particular to an electric vehicle motor comprising a stator and a rotor, and the rotor is provided with magnetic steel. Background technique [0002] A Chinese utility model patent (publication number CN201717691U) discloses a magnetic steel ring attached between the rotors of the electric vehicle motor, including a magnetic steel ring installed in the hub of the electric wheel, and a magnetic steel sheet is installed on the inner wall of the magnetic steel ring. There is an equidistant spacing S between the magnetic steel sheets, and the inner wall of the magnetic steel ring is formed with a flat boss, which is in contact with the magnetic steel sheets, and a glue guide groove is formed on the flat boss. The number of magnetic steel sheets described in this program is constant, but the width of each magnetic steel sheet is narrowed, leaving a distance, and the distances are also different accordin...
