Description

High speed direct current brushless permanent magnet motor stator winding

Technical field

The utility model belongs to machine field, relates in particular to a kind of high speed direct current brushless permanent magnet motor stator winding.

Background technology

Along with control technology and components and parts application and development, the application of brushless electric machine is more and more wider, with being arranged, compares by the brush direct current machine, the technology of brush-less permanent magnetic direct current machine has obtained significant progress, the permanent-magnet brushless DC electric machine climbing capacity of existing electric vehicle is poor, moment of torsion is little, and speed per hour is generally lower, speed rises to 40Km has not had the rising potentiality, and the high speed characteristics of motor and low-speed characteristic be a pair of contradiction, the speed ability of its motor and torsional performance, and both can not take into account simultaneously, because the torque of brush-less permanent magnetic direct current machine becomes positive correlation with umber of turn, and speed and the moment of torsion relation of being inversely proportional to; And because the number of magnetic poles of brush-less permanent magnetic direct current machine is fixed, existing change number of poles technology is impracticable, and therefore, the control winding becomes an approach that improves the dc brushless motor combination property.

The utility model content

The utility model technical issues that need to address provide a kind of high speed direct current brushless permanent magnet motor stator winding that starting torque is big, speed-raising is fast, climbing capacity is strong, efficient is high that has.

For addressing the above problem, technical solution adopted in the utility model is: a kind of high speed direct current brushless permanent magnet motor stator winding, the motor stator line embedding groove is divided into N adjacent area successively, each regional groove number equates, wherein N is integer and N 〉=2, each zone is equipped with three phase winding A, B, C, and the head end of the same phase winding in each zone links together, and the tail end of all phases in each zone links together.

The head end of the same phase winding in each zone links together, and forms the external lead wire tap of three phase lines of motor stator winding.

Adopt the beneficial effect that technique scheme produced to be: by with motor stator line embedding groove subregion, and the homophase phase line head end that each is regional links together, the tail end of all phase lines connects together, form the concatermer motor, have characteristics such as starting torque is big, speed-raising is fast, efficient is high, climbing capacity is strong, can satisfy the demand of high pulling torque, high rotating speed application, to electricity at a high speed rub, the development of automotive field made contribution.
