Description
Technical Field
The utility model relates to the field of electric machines, especially, relate to a stator structure of high energy density motor.
Background
At present, the cost and pressure of the motor are higher due to the fact that high-performance ferrite magnetic steel is expensive. In order to reduce the cost and improve the motor power, engineering technicians provide a plurality of methods and measures: the method mainly comprises the following steps: the common ferrite type motor is adopted, and the grade of the silicon steel sheet is reduced. The common ferrite permanent magnet has poor performance and low energy density, and is not beneficial to the miniaturization of the motor; and the pure reduction silicon steel sheet trade mark then faces the loss grow of motor under the abominable operating mode of high load, leads to the too high problem of motor temperature. In the existing permanent magnet motor stator structure, the magnetic bridges at the end parts of the two layers of permanent magnet mounting grooves are not optimized generally, magnetic lines of force are difficult to pass through, and a point magnetic field directly acts on the end parts of the permanent magnets to cause the end parts of inner layer ferrites with weaker magnetic performance to be demagnetized. Therefore, further improvements are needed.
