Abstract

The invention discloses a motor rotor and a rotary motor containing the motor rotor. The motor rotor comprises a rotary shaft, a rotor iron core, first axial magnetic steel, second axial magnetic steel, a rotor sleeve and a first magnetism isolation groove. The rotor iron core is coaxially connected with the rotary shaft. The first axial magnetic steel is arranged on one end surface of the rotary iron core; the first axial magnetic steel is provided with a first magnetic pole; and the first magnetic pole faces the rotary iron core. The second axial magnetic steel is arranged on the end surface of the rotary iron core; the second axial magnetic steel is provided with a second magnetic pole; and the second magnetic pole faces the rotary iron core. The rotary sleeve is adjacently arranged at one side (which is far away from the first axial magnetic steel and the second axial magnetic steel) of the rotor iron core. The first magnetism isolation groove is formed in the rotor iron core along the radial direction of the rotary iron core and is located between the first axial magnetic steel and the second axial magnetic steel, so as to separate the first magnetic pole and the second magnetic pole.

Description

technical field [0001] The present invention relates to a rotating electric machine, and in particular to a rotating electric machine with a magnetic steel construction design. Background technique [0002] For the motor, the material of its magnetic steel is preferably NdFeB. However, the price of rare earth materials is rising at present. In order to save costs, the industry hopes to use permanent magnet materials with low magnetic properties and cheap prices (such as ferrite) To replace NdFeB. However, since the remanence of ferrite materials is only 0.2~0.44T, and the maximum energy product is only 6.4~40kJ / m 3 , so a simple replacement will reduce the output power of the motor and reduce the efficiency. [0003] Therefore, in the prior art, there is a method of increasing the axial length of the rotor (increasing the tangential magnetic steel in the rotor core) to increase the cross-sectional area of ​​the magnetic steel to increase the output power. However, this wi...
