Embodiment Construction

[0024] In order to make the method of the present invention clearer and clearer, it will be described in further detail below in conjunction with specific embodiments and accompanying drawings:

[0025] Embodiment No. 1 of the present invention, such as figure 1 , figure 2 , image 3 Shown:

[0026] The motor rotor 1 includes a shaft 14 , fibers 10 , glue 15 , two rotor segments 101 , and two dynamic balance correction plates 11 .

[0027] Each rotor segment 101 is quasi-cylindrical and includes four sector magnets 131 and 132 and an iron core 12 .

[0028] Among the magnets 131 and 132, there are 2 pieces of N pole magnets 131 with the N poles facing the outer surface, and 2 pieces of S pole magnets 132 with the S poles facing the outer surface. The N pole magnets 131 and the S pole magnets 132 are alternately arranged in a symmetrical manner distributed.

[0029] The iron core 12 is a quasi-cylindrical body with a hole in the middle; between the shaft 14 and the magnet...

Abstract

The invention relates to the electrical field, in particular to a motor rotor used in a motor, a motor applying the motor rotor and a method for calculating an angle of the motor rotor. The motor rotor is provided with a shaft in the middle, the shaft passes through more than two rotor sections, and the rotor sections are mutually staggered for a certain angle; the angle is calculated according to an equation that a is less than or equal to 360 / [s,4] / n; the brushless motor also comprises an end cover and a stator; the motor applying the motor rotor can be matched with different quantities of rotor sections, and series motors with different powers are expanded; meanwhile, the rotor sections are mutually staggered for a certain angle, counter electromotive force harmonic of the motor is lower, and performance of the motor is improved.

Description

technical field [0001] The invention relates to the electrical field, in particular to a motor rotor used in a motor and the motor. Background technique [0002] The motor rotors used in motors now need to prepare rotor segments of different lengths for motors of the same series with different powers, which is troublesome to produce; in addition, in order to reduce the back electromotive force harmonics of the motor, the rotor segments need to be made with oblique poles, or the stator should be made Into a chute, the cost is relatively high. Contents of the invention [0003] The main purpose of the present invention is to improve the existing technology, use rotor segments of different lengths to spell out motors of the same series with different powers; in addition, each rotor segment is staggered by a certain angle, which reduces the back electromotive force harmonics of the motor and improves the performance of the motor Effect. [0004] Preferably, the motor rotor i...
