Magnetic levitation middle shaft motor

Abstract

Lubricating oil is needed in a common motor middle shaft to reduce the friction force, the resistance of the motor can be increased as the lubricating oil of the motor is reduced, and the current andvoltage of the motor can also be increased, the use amount of electricity is increased, the common motor needs to be maintained, the maintenance is troublesome and consumes longer time, and the service life is short. The magnetic levitation middle shaft motor suspends the middle shaft rotor by means of the permanent magnet and the electromagnet, and the current and voltage are controlled, meanwhile, the magnetic field is controlled to simultaneously control the rotating speed of the middle shaft, and the magnetic-levitation middle shaft motor solves the problems of long service life, energy conservation and high maintenance speed. The service time of the motor is prolonged, the middle shaft does not need the lubricating oil, and the magnetic levitation middle shaft motor does not have resistance, the energy consumption can be reduced by reducing the frequency and increasing the frequency, and the maintenance time can be reduced without the friction force, and a variable-frequency technology can be realized, a magnetic-levitation middle shaft motor also can be used in the field of generators, the middle shaft does not have friction force, and the electric power can be obtained through the rotating speed with the minimum resistance.

Description

technical field [0001] The invention relates to the field of motors, in particular to the field of maglev center shaft motors. Background technique [0002] The life of ordinary motors is relatively short, the maintenance of the motor is troublesome, and the maintenance time is relatively long. The motor needs lubricating oil for the center shaft. The lack of oil in the center shaft of the ordinary motor will increase the power consumption, and will cause the motor to stop or damage the motor. Ordinary motor speed is limited and cannot reach low frequency speed. Contents of the invention [0003] The present invention is a maglev center shaft motor. [0004] The maglev center shaft motor solves the above technical problems. The maglev center shaft motor can realize that the center shaft does not need lubricating oil. The center shaft brushless motor, the center shaft has no friction and can use the frequency conversion technology to achieve one hertz frequency conversion...
