Abstract
The utility model relates to a novel stator structure of a permanent magnet driving motor for an electric automobile. The novel stator structure is composed of a stator tooth portion and a stator yoke portion, and is characterized in that the stator tooth portion and the stator yoke portion are oriented silicon steel plates and are laminated by means of adhesion or riveting; a clamping groove structure is disposed in the bottom of the stator tooth portion; the stator yoke portion is provided with a slot; the stator tooth portion is fixedly connected with the slot of the stator yoke portion in a cooperation manner; a stator winding is a centralized winding and is wound on the stator tooth portion. The stator tooth portion is separated from the yoke portion, and a coil can be wound on an iron core of the tooth portion and then assembled with an iron core of the yoke portion. Since the oriented silicon steel is adopted to manufacture laminates of the stator tooth portion. Therefore, both the groove full rate and the tooth portion magnetic flux density are improved, the eddy current loss is reduced, the motor performance is optimized, and good production manufacturability is guaranteed.
Description
Technical field
The utility model relates to a kind of a kind of novel stator structure of used for electric vehicle permanent magnet drive motor, belongs to the technical field of electric powered motor design of electrical motor, particularly a kind of stator core assembly of permagnetic synchronous motor.
Background technology
Power motor is the core assembly of electric automobile, and its performance directly affects dynamic property, economy, reliability and the fail safe of car load, and commonly used is permagnetic synchronous motor at present.
The permanent-magnetic synchronous motor stator iron core divides tooth section and yoke section, and both can be one, also can separate, and the non-orientation silicon steel thin slice closed assembly that usually is shaped by punching forms.
The permanent-magnetic synchronous motor stator winding is divided into usually concentrates two kinds of winding and distributed winding.With distributed winding, compare, concentrate the winding of winding simple, good manufacturability, end be shorter, more easily realizes automatic batch production.Yet when the shortcoming of concentrated winding electric machine was automatically to roll off the production line, copper factor was on the low side, and tooth section is wider, under the effect in magnetic field, easily formed eddy current, caused certain loss.
Summary of the invention
The purpose of this utility model is to provide a kind of a kind of novel stator structure of used for electric vehicle permanent magnet drive motor, its stator teeth and yoke part from, can be after tooth section iron core winding coil again with yoke section iron core assembly, and employing has orientation silicon steel to manufacture the stator teeth lamination, can either improve copper factor, can improve again tooth section magnetic flux density, reduce eddy current loss, optimize motor performance, and guarantee good production technology.
The technical solution of the utility model is achieved in that a kind of novel stator structure of used for electric vehicle permanent magnet drive motor, by stator teeth, stator yoke section, formed, it is characterized in that: stator teeth, stator yoke section are the silicon steel sheet that orientation is arranged, and by bonding or riveting method, are overrided to form; Notch is arranged at the stator teeth bottom, and stator yoke section has slot, and stator teeth is fixed and is connected with the slot of stator yoke section by notch, and stator winding is for concentrating winding, coiling on stator teeth.
Good effect of the present utility model is to adopt tooth section and yoke part separating structure, and use the orientation silicon steel material is arranged, can either solve to a certain extent eddy current problem, improve the stator teeth magnetic flux density, can improve copper factor again, when optimizing motor performance, guarantee good production technology.
The accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is local structural graph of the present utility model.
Fig. 3 is tooth section of the present utility model and yoke portion connecting structure figure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1, a kind of novel stator structure of used for electric vehicle permanent magnet drive motor, by stator teeth 1, stator yoke section 2, formed, it is characterized in that: stator teeth 1, stator yoke section 2, for the silicon steel sheet of orientation is arranged, are overrided to form by traditional bonding or riveting method; Notch is arranged at stator teeth 1 bottom, and stator yoke section 2 has slot, and stator teeth 1 is fixed and is connected with the slot of stator yoke section 2 by notch, and stator winding 3 is for concentrating winding, coiling on stator teeth 1.
Stator of the present utility model adopt stator teeth and stator yoke partly from structure, stator teeth 1 adopts the silicon steel material that orientation is arranged, make the stator teeth magnetic flux only can be along the motor Radial Flow, as shown in Figure 2, stator winding 3 adopts concentrates winding, coiling on the stator teeth 1 that laminates in advance, be installed to again in stator yoke section 2, as shown in Figure 3, stator teeth 1 is fixed and is connected with the slot of stator yoke section 2 by notch, after the stator tooth yoke installs, with epoxy material, solidify stator, guarantee stabilized structure and good heat conductive.
