Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0022] Such as figure 1 As shown, this embodiment provides an in-wheel hub motor, which includes a rotor 1 and a stator core 4, the rotor 1 is sleeved on the outside of the stator core 4, and the rotor 1 is provided with a plurality of evenly distributed magnetic steel slots. A magnetic steel 2 is embedded in the magnetic steel groove.

[0023] The magnetic steel 2 is installed in the magnetic steel slot in an embedded manner, which can effectively reduce the manufacturing cost of the motor, and has the advantages of high manufacturing efficiency and strong stability.

[0024] Specifically, the magnetic steel groove is V-shaped, which includes a first magnetic steel groove and a second magnetic steel groove at an angle to each other, and the intersection point of the first magnetic steel groove and...

Abstract

The invention relates to the technical field of motors, and especially relates to an embedded hub motor and an electric vehicle employing the same. The embedded hub motor comprises a rotor and a stator iron core. The rotor sleeves the stator iron core. The rotor is provided with multiple evenly-distributed magnetic steel slots, and magnetic steel is embedded into the magnetic steel slots. The invention also provides an electric vehicle employing the above embedded hub motor. The magnetic steel is arranged in the rotor slots in an embedded manner, so manufacturing costs of the motor are effectively reduced. Moreover, the embedded hub motor has the advantages of high manufacturing efficiency and high stability.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an in-wheel hub motor and an electric vehicle using the same. Background technique [0002] Electric two-wheeled vehicles are currently the most common type with wheel hubs, and there are also a small number of side-mounted and mid-mounted types. The hub motor mainly adopts the outer rotor structure, and the magnetic steel adopts the surface mount type. Simple structure and high power density. With the development of the electric two-wheeled vehicle industry and fierce market competition, reducing costs and improving power performance have become the key to gaining a foothold in the market, and the in-wheel motors are constantly optimized. The surface-mounted hub motor has been optimized to the limit at present, and it is difficult to optimize the solution that can reduce the cost and ensure the power performance. Contents of the invention [0003] The purpose of the present ...
