Description
Technical Field
The utility model relates to the field of motors, in particular to a rotor with a double magnetism isolating structure and a motor.
Background
The magnetic isolation bridge is a magnetic isolation measure adopted in the permanent magnet motor and is used for preventing the over-high leakage coefficient of the permanent magnet from causing the over-low utilization rate of the permanent magnet. The function of the magnetism isolating bridge is similar to that of a dam of water flow, and the magnetism induction wire can be guided to effectively penetrate out of the permanent magnet to participate in cutting, so that the working efficiency of the motor is improved.
For low-speed large-torque motors, such as pumping unit motors used in oil fields, low-speed large-torque direct-drive or semi-direct-drive motors are generally adopted, and the rotating speed is relatively low and the number of stages is large. For a large motor, the higher the efficiency is, the lower the heating value is, so that the loss generated in the working process is larger, and the higher the efficiency is, the better the preferable working condition is. For a motor with low speed and large torque, copper loss is a main loss, the main magnetic flux of the permanent magnet motor is established by the permanent magnet, and if the utilization rate of the permanent magnet is not high, when the whole armature reaction is affected, the customized current needs to be larger, so that larger copper loss can be caused, the heating of the motor can be increased, and the efficiency of the motor is reduced. Therefore, the treatment measures for isolating the magnetic poles of the rotor and reducing the magnetic leakage are very necessary for saving energy and improving efficiency.
