Abstract

The utility model discloses an enhanced high efficiency permanent magnet motor. A motor casing is polygonal. The middle part of each side extends inwardly to divide the interior of the casing into a number of spaces. Motor magnets are respectively placed in each space. The enhanced high efficiency permanent magnet motor provided by the utility model has the advantages that the strength of the casing is enhanced; the size is small; the space is saved; the materials are saved; parts in the motor are highly integrated; and the power density of the single motor is greatly improved compared with a traditional round motor.

Description

The enhancement mode efficient permanent magnet motor
Technical field
The utility model relates to a kind of electric motor of automobile, particularly a kind of enhancement mode efficient permanent magnet motor.
Background technology
Existing electric motor of automobile is traditional circular motor, because wall thickness is even, so insufficient strength is easy to generate distortion.The conventional motors volume is big, is installed in the less space environment of automobile, can take the space of other parts; The magnet volume of the circular motor of tradition is big, and it is big to take the motor internal space, and utilance is low, so power density is lower; The circular motor of tradition is difficult for installing, if be installed in the rolling phenomenon takes place easily on some plane, and installing needs special positioner.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of volume little, the enhancement mode efficient permanent magnet motor that power density is higher.
In order to solve above technical problem, the utility model provides a kind of enhancement mode efficient permanent magnet motor, motor case is polygon, middle part, every limit extends internally casing inside is divided into several spaces, place the motor magnet in each space respectively, increase magnetic flux, improved the magnetic flux utilance.
Intersection, the every limit of described polygon housing face is fillet, or is chamfering.
Superior effect of the present utility model is: this motor has improved the intensity of housing, and volume is little, has both saved the space, has saved material again, and each part height of motor internal is integrated, and the traditional circular motor of the power density ratio of single motor improves greatly.
Description of drawings
Fig. 1 is the cross sectional representation of the utility model polygon motor;
Fig. 2 is the cross sectional representation of fillet for the polygon electric machine casing;
Fig. 3 is the cross sectional representation of chamfering for the polygon electric machine casing;
The number in the figure explanation
1-polygon housing; 2-motor magnet.
Embodiment
See also shown in the accompanying drawing, the utility model will be further described.
As shown in Figure 1-Figure 3, the utility model provides a kind of enhancement mode efficient permanent magnet motor,, motor case is hexagon, middle part, every limit extends internally casing inside is divided into six spaces, place the motor magnet in each space respectively, the motor magnet is by clamping, or one-body molded, or bonding way is finished installation, increase magnetic flux, improved the magnetic flux utilance.And cut apart line segment and can substitute traditional motor magnetic tile folder.Intersection, the every limit of polygon housing face is fillet, or is chamfering.It is can be by punch press one time punching molded or draw high moulding that housing adds man-hour.

Claims (2)

1. enhancement mode efficient permanent magnet motor, it is characterized in that: described motor case is polygon, middle part, every limit extends internally casing inside is divided into several spaces, places the motor magnet in each space respectively.
2. enhancement mode efficient permanent magnet motor according to claim 1, it is characterized in that: intersection, the every limit of described polygon housing face is fillet, or is chamfering.
