Abstract

The invention provides a motor rotor, a motor and a compressor. The motor rotor comprises a rotor body and adjusting parts, wherein the rotor body is provided with a plurality of accommodating groovesin the circumferential direction, the accommodating grooves are internally provided with a plurality of permanent magnets capable of moving along the length direction of the accommodating grooves, and the outer side edges of each accommodating grooves are provided with magnetic isolation edges and magnetic conduction edges; and the adjusting parts are arranged at two ends of each permanent magnetto enable the permanent magnets to move along the accommodating grooves. under the action of the adjusting parts, the permanent magnets can move to different positions, and the effective magnetic conduction length of the polarity edge of the permanent magnet and the magnetic conduction edge at the outer side of the accommodating groove is changed, so that effective magnetic conduction area at theouter side of the permanent magnet is adjusted, the effect of adjusting the magnetic field of the motor rotor is achieved, and the rotating speed range of the motor can be effectively adjusted.

Description

technical field [0001] The invention relates to the technical field of compression devices, in particular to a motor rotor, a motor and a compressor. Background technique [0002] Permanent magnet motors are widely used due to their advantages of high efficiency and high power density. The permanent magnet motor rotor magnetic field is generated by permanent magnets, so it has the characteristic that the induced voltage increases with the increase of the speed. Since the magnetic flux of the permanent magnet is difficult to adjust, the induced voltage increases proportionally with the increase of the rotational speed. Its induced voltage value is limited by the voltage of the power supply, so the speed range of the permanent magnet motor is also limited. [0003] In order to increase the speed range of the permanent magnet motor, part of the current is passed through the stator coil to offset the magnetic field generated by the permanent magnet, thereby reducing the induce...
