Embodiment Construction
[0036] Such as figure 1 As shown, in the rotor permanent magnet flux switching hub motor of the present invention, the rotor permanent magnet flux switching motor is used as the driving motor, and the stator and rotor of the motor are arranged in the form of outer rotor-inner stator, that is, the inner is the stator, and the outer circumference is the rotor.
[0037] Among the various in-wheel motor schemes that have been seen so far, the motor rotor and the rim are connected in the following two ways: the outer rotor is directly connected to the rim by welding; the inner rotor is indirectly connected to the rim through a gear box. The rotor permanent magnet flux switching in-wheel motor of the present invention abandons the above two types of methods. Such as figure 2 In the shown embodiment, the rotor unit is directly embedded on the rim 1, and the specific processing method is as follows: a matching dovetail groove 2a is provided on the rotor core 2 and the boss 6 of the...

The invention discloses a rotor permanent magnet type magnetic flux switching wheel hub motor, which includes a wheel rim, a stator core, an armature winding wound on the stator core, and a plurality of rotor units; the rotor units are fixed on the In the rim, the rotor unit includes a permanent magnet and rotor cores arranged on both sides of the permanent magnet; the magnetization direction of the permanent magnet is tangential magnetization and the magnetization direction of each permanent magnet is the same. The motor of the present invention has the advantages of large power, strong anti-saturation and overload capability, large reluctance torque, good magnetic weakening performance, wide speed regulation range, high manufacturing integration, and suitable for modular manufacturing process.
Description
technical field [0001] The invention belongs to the technical field of motor manufacturing, in particular to a rotor permanent magnet motor based on the magnetic flux switching principle. Background technique [0002] With the deepening of the global energy crisis, energy-saving and efficient electric vehicles have been paid more and more attention by the government and society. At present, the driving methods of electric vehicles represented by electric vehicles are mainly divided into two categories: one is the direct drive of distributed hub motors, which are mainly used in electric bicycles, electric scooters, four-wheel independent drive electric vehicles and other fields ; The other is the indirect drive of a centralized motor with a gearbox, which is mainly found in the field of power-concentrated electric vehicles and hybrid vehicles. [0003] On the other hand, with the rapid growth of the national economy, the number of residents' car ownership is increasing year ...
