Embodiment Construction

[0051] By the above-described drawings, embodiments have been illustrated embodiment of the present invention is clear, it will be hereinafter described in more detail. These figures and written description are not intended to in any way limit the scope of the inventive concept, but by reference to specific embodiments to those skilled in the inventive concept described.

[0052] figure 1 Round flat wire windings and winding a schematic structural diagram of the embodiment of the present invention, wherein figure 1 In (a) is a schematic view of a circular cross section wire windings, figure 1 In (b) is a schematic structural cross-winding flat wire section. Stator winding is generally used round wire windings, the advantage of a simple wound, a good process and high heat dissipation efficiency. But the motor output is closely related to the performance of the motor structure parameters under different operating conditions, while the stator winding motor output is an important fac...

Abstract

Embodiments of the present invention provide a dual-stator motor, a motor control system and a control method. The dual-stator motor includes a first stator assembly, a second stator assembly, a rotor assembly, and a motor control unit; wherein the winding of the first stator assembly adopts a circular The winding of the second stator assembly adopts flat wire; the rotor assembly is fixed on the output shaft of the motor and passes through the first stator assembly and the second stator assembly; the motor control unit is connected with the first stator assembly and the second stator assembly The electrical connection is used to control the first stator assembly to drive the rotor assembly to drive the output shaft to rotate, so that the motor operates at a high speed; or, to control the second stator assembly to drive the rotor assembly to drive the output shaft to rotate, so that the motor operates at a low speed In this case, when the frequency of the alternating current of the motor is high, the problem of high loss caused by the skin effect of the flat wire winding is solved, and the performance of the motor is improved.

Description

Technical field [0001] Technical Field The present invention relates to a motor, particularly to a double-stator motor, the motor control system and control method. Background technique [0002] In recent years, the rapid development of new energy vehicles, industry competition is increasing, while the new energy automobile power density requirements are also increasing. From a technical point of view, in order to enhance the power density of the main drive system, and the proposed technical solution developed flat wire. [0003] With advances in technology, flat wire windings of the motor for its high slot fill, thermal conductivity, heat dissipation and the torque output performance than a round wire wound motor advantages are a large number of popular applications. However, the skin effect flat wire winding machine at high speed significantly, resulting in loss of flat wire windings of the AC higher than the losses of a round wire windings, flat wire windings has been limited ...
