Problems solved by technology

[0002] Today's world has entered the era of electrification. More and more electrical equipment has motor parts, such as electric fans. Since the electric fan generates forward wind force, it will produce a backward reaction force on the main shaft of the electric fan. This reaction The force will act on the motor bearing, because the motor bearing is designed to withstand radial pressure instead of axial pressure, and the axial pressure generated by the reaction force will increase the friction loss of the motor bearing, resulting in serious heat generation, Generates noise and reduces motor life

Abstract

The invention discloses a magnetic suspension type motor base. A transmission main shaft of the motor base is in rigid connection with an output shaft of a motor through a coupling; an upper magnetic ring, a middle magnetic ring and a lower magnetic ring are circular hollow magnets; the transmission main shaft penetrates through central circular holes of the upper magnetic ring, the middle magnetic ring and the lower magnetic ring from top to bottom, wherein the transmission main shaft is tightly connected with the middle magnetic ring; the upper magnetic ring and the lower magnetic ring are movably connected with the transmission main shaft; gaps are reserved among the upper magnetic ring, the middle magnetic ring and the lower magnetic ring; the upper magnetic ring, the middle magnetic ring and the lower magnetic ring are fixed in an upper magnetic ring seat, a middle magnetic ring seat and a lower magnetic ring seat; an upper auxiliary excitation coil, a middle auxiliary excitation coil and a lower auxiliary excitation coil are arranged on the upper magnetic ring, the middle magnetic ring and the lower magnetic ring respectively; and the upper magnetic ring seat, the middle magnetic ring seat and the lower magnetic ring seat are fixed on a top seat through a plurality of long screws. By the magnetic suspension type motor base, counter-acting force can be transferred to the magnetic suspension type motor base by magnetic force, and axial force born by a motor bearing can be reduced or even eliminated.

Description

technical field [0001] The invention relates to a motor mount, in particular to a magnetic levitation motor mount. The magnetic levitation motor mount is suitable for electric fans, electric turbofans, ship electric drives, propeller propellers driven by internal combustion engines, etc., which can generate propulsion and provide power to motors. Where there is a reactionary force. Background technique [0002] Today's world has entered the era of electrification. More and more electrical equipment has motor parts, such as electric fans. Since the electric fan generates forward wind force, it will produce a backward reaction force on the main shaft of the electric fan. This reaction The force will act on the motor bearing, because the motor bearing is designed to withstand radial pressure instead of axial pressure, and the axial pressure generated by the reaction force will increase the friction loss of the motor bearing, resulting in serious heat generation, Generate noise...
