Stator for axial clearance type motor and axial clearance type motor

Abstract

The invention provides a stator for an axial clearance type motor and the axial clearance type motor. Stator teeth stator windings are symmetrically arranged on the two end faces of the stator to support the axial clearance type motor to adopt a dual-rotor mode which can make the stress of a rotating shaft balanced, so that improvement in the bearable maximum torque and rotating speed of the axial clearance type motor is facilitated. In addition, a stator slot formed on the stator replaces a collector ring and a cooling shell, so that the structure of the axial clearance type motor can be simplified. Moreover, clearance slots of the stator are equal in width along a radial direction, so that the utilization of air clearances is improved; and chambers are formed at the end part edges of the stator teeth of the stator, so that the dispersion of lines of magnetic force can be suppressed. Therefore, the specific power of the axial clearance type motor can be improved.

Description

technical field [0001] The invention relates to motor technology, in particular to a rotor of an axial gap motor and an axial gap motor using the stator. Background technique [0002] Axial gap motor is the core power component of electric vehicles, and its power performance plays a vital role in electric vehicles. Among them, the specific power is an index used to measure the dynamic performance of the axial gap motor, and the specific power is equal to the ratio of the maximum power to the mass of the axial gap motor. [0003] However, the existing technology often pays more attention to how to improve various factors that directly affect the maximum power, such as heat dissipation effect, magnetic gathering performance, and maximum torque, so as to increase the maximum power of the axial gap motor, but at the same time, it is It is difficult to prevent the structure of the axial gap motor from being complicated, and thus resulting in an increase in the mass of the axial ...

[0003] However, the existing technology often pays more attention to how to improve various factors that directly affect the maximum power, such as heat dissipation effect, magnetic gathering performance, and maximum torque, so as to increase the maximum power of the axial gap motor, but at the same time, it is It is difficult to prevent the structure of the axial gap type motor from being complicated, and thus resulting in an increase in the mass of the axial gap motor

[0004] Therefore, the existing technology cannot really effectively improve the specific power of the axial gap motor, and it may further hinder the improvement of the maximum power due to the complexity of the structure, and lead to an increase in cost
