Title:
LARGE PERMANENT MAGNET ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/233189
Kind Code:
A1
Abstract:
Provided is a large permanent magnet electric motor, comprising a stator (1) and a rotor (20), wherein the stator (1) and the rotor (20) are respectively provided with a plurality of magnet separation areas in an axial direction, a plurality of stator permanent magnet fixing boxes (7) each internally provided with a stator permanent magnet (5) are evenly distributed in an inner side of a stator magnet separation area (4), a plurality of rotor permanent magnet fixing boxes (26) each internally provided with a rotor permanent magnet (25) are evenly distributed on an outer peripheral face of a rotor magnet separation area, the rotor permanent magnet fixing boxes are arranged such that each row forms a line in an axial direction of the stator permanent magnet (5), and the rotor permanent magnet fixing boxes are arranged in a stepped shape in an axial direction of the rotor permanent magnet (25), so that the rotor permanent magnet (25) and the stator permanent magnet (5) cooperate to form a rotating magnetic field capable of driving the rotor (20) to rotate; a rotor (20) axial displacement device can control the time and rotational speed of the stopping or starting of the rotor (20); and only a small amount of a starting power supply is required. Most high-power mechanical energy is manufactured by means of relying on the magnetic energy of hundreds of pairs of stator permanent magnets (5) and rotor permanent magnets (25), such that a good energy-saving effect is realized; and the present invention can drive a large generator to generate electricity, drive vehicles and ships to travel, etc.
