Abstract

A rotating-magnetic-field generator comprises a power source and a magnetic field generator body. The magnetic field generator body is composed of an even number of arc-shaped permanent magnet units enclosing in a circle, and magnet poles of the neighboring permanent magnet units are opposite. An inner magnet space provided with a stator is formed in the magnetic field generator body, the stator is composed of a shaft core, a silicon steel sheet arranged on the shaft core and a coil winding arranged on the silicon steel sheet, and the stator and the magnetic field generator body jointly form the power source. Magnetic field lines generated by all the permanent magnet units to the inner magnet space provide an excitation magnetic field to the power source, when the coil winding of the stator into a current, the stator is fixed, and then the magnetic field generator body rotates around the stator. When the magnetic field generator body rotates, each permanent magnet unit launches the magnetic fields outwardly, and the magnetic field lines rotate with the magnetic field generator body to form a rotating magnetic field. By the arrangement, structural parts of the rotating-magnetic-field generator can be reduced, and production cost can be effectively lowered.

Description

technical field [0001] The invention relates to a magnetic field generator, in particular to a rotating magnetic field generator.
