Specific implementation mode
To keep the purpose of this utility model, technical solution and advantage clearer, elaborated below with specific embodiment
The more technical details of the utility model.
As shown in Figs 1-4, a kind of rotor, including shaft core 1 and the magnet steel 2 that is fixed in shaft core 1, this motor turn
Son directly replaces the silicon steel sheet of conventional motors with magnet steel 2, other than mandrel 1, all using magnet material, production technology letter
Single, easy to operate, in the present embodiment, magnet steel part is formed by connecting by four sections of identical magnet steel 2, makes 2 module of magnet steel of rotor
Change, improve production efficiency, the suitable magnet steel 2 of quantity can be selected according to the height of motor, there is the circle of through-hole centered on magnet steel 2
Column structure, and magnet steel 2 is along the circumferential direction divided into four magnetic poles, the polarity of two neighboring magnetic pole is opposite and two neighboring magnetic pole
Between line of demarcation 11 tilted with respect to shaft core 1 axis, magnet steel 2 is arranged to certain angle of inclination when magnetizing and magnetizes, and using special
Different magnetization method makes four magnetic poles of formation on a monoblock magnet steel 2 be formed with the poles N, the poles S, the poles N, the poles S four in the present embodiment
A magnetic pole, the line of demarcation 11 between two neighboring magnetic pole are tilted with respect to 1 axis of shaft core, change the magnetic structure of rotor so that electricity
Machine can be according to client to motor performance while capable of working normally demand select different angles of inclination.As shown in figure 5, magnetic
Line of demarcation 11 between the adjacent pole of steel 2 is more than 0 degree with respect to the inclined inclination angle of 1 axis of shaft core, is less than 90 degree, the size shadow at inclination angle
The rotating speed and torque of motor are rung, inclination angle is bigger, and motor speed is bigger, and torque is smaller.
When inclination angle is 5 degree, the rotating speed of motor can reach 3500r/min, and the torque of motor can reach 15N.m, motor speed
Slowly, torque is big.
When inclination angle is 9.5 degree, the rotating speed of motor can reach 4500r/min, and torque can reach 12N.m, motor speed is fast,
And torque is big, this angle is the equalization point of optimal torque and speed, and in such motor, this speed and torque are all visitors
Parameter in the ideal of family.
When inclination angle is 15 degree, the rotating speed of motor can reach 6000r/min, and the torque of motor can reach 7N.m, motor speed
Degree is fast, torque is small.
In the present embodiment, as shown in Figs. 1-2, in order to make four sections of magnet steel 2 assemble up and can work normally, every section of magnet steel
11 front end of line of demarcation between 2 magnetic pole is on the same straight line, and locating slot 21 and positioning protrusion are both provided on every section of magnet steel 2
22, by the mating connection of locating slot 21 and positioning protrusion 22 between each section of magnet steel 2, when connection, by the positioning protrusion 21 of magnet steel 2
It is stuck in the positioning groove 22 of adjacent magnet steel 2, plays positioning action, then use plug fixed from centre, then bonded with glue
Good magnet steel 2, finally extracts plug out.
Operation principle is as follows：
As shown in figure 3, generating magnetic field, the orthogonal effect in magnetic field with rotor, this practicality after stator coil is powered
Novel rotor structure is that from below to up, the poles N and S in magnetic field are divided into four sections and tilt certain angle successively, and the magnetic field of coil is made
It firmly acts on most next section, the angle that the angle followed by second that drive rotor rotates saves magnet steel 2 just returns to first
The position of the magnet steel of section continues to press on rotor motion, goes down successively, rotor will continuous rotation get up.
Although the utility model is to be described with reference to specific embodiments, this description is not meant to the utility model
It is construed as limiting.With reference to the description of the utility model, other variations of the disclosed embodiments are all for those skilled in the art
