Abstract
The invention discloses a rotor magnetic ring of a permanent magnet motor. The rotor magnetic ring comprises a rotor shell, a magnetic ring body and grooves, wherein the cross section of the rotor shell is of an annular shape, a plurality of grooves are arranged on the surface of the rotor shell, the rotor shell and the magnetic ring body are integrated through plastic magnetic die casting, a plurality of N poles and S poles are embedded onto the magnetic ring body and arranged at equal intervals, the rotor shell and the magnetic ring body also can be bonded, and the rotor shell is made of low-carbon steel. Since the rotor shell and the magnetic ring body are integrated through plastic magnetic die casting, the rotor magnetic ring is firm in structure, the two heads of the magnetic ring body cannot shift, and the rotor magnetic ring is prevented from falling off during high-speed running and has a long service life; the rotor shell is made of low-carbon steel, the magnetism can be enhanced by 3% due to the integration of the magnetic ring body and the steel, the rotor magnetic ring has high magnetism and stable performance; and the rotor shell and the magnetic ring body also can be connected by bonding, so that the rotor magnetic ring has the characteristics of high magnetic field, material saving and cost reduction.
Description
Technical field
The present invention relates to technical field of motors, particularly a kind of permanent magnet machine rotor magnet ring.
Background technology
In recent years, along with the fast development of power electronic technology, microelectric technique, New-type electric machine control theory, magneto is applied rapidly, on the rotor of magneto, magnet ring is installed and is reduced electromagnetic interference, the normal use of support equipment.On traditional rotor, inlay magnetic sheet, degree of being connected firmly is poor, the damage that easily comes off in the process of running up, and also magnetic density is low, and even not, useful life is short, increases maintenance cost, affects the economic benefit of enterprise.
Summary of the invention
For addressing the above problem, the object of this invention is to provide a kind of sound construction, running is stable, magnetic field strong, the permanent magnet machine rotor magnet ring of long service life.
For achieving the above object, technical scheme of the present invention is:
A permanent magnet machine rotor magnet ring, comprises rotor case, magnetic ring body, groove, and described rotor case cross section is annular, and surface is provided with several grooves, and rotor case and magnetic ring body are by moulding the combination of magnetic pressure casting one.
As preferably, on described magnetic ring body, inlaying some impartial N utmost point magnetic pole and S utmost point magnetic poles of arranging.
As preferably, described rotor case and magnetic ring body combination also can be bonding.
As preferably, described rotor case is made by mild steel.
Rotor case of the present invention and magnetic ring body are integrally formed by moulding magnetic pressure casting, sound construction, magnetic ring body two can not be shifted, and prevents from coming off in the process of running up, and increases the service life, rotor case is made by mild steel, magnetic ring body is combined and can be increased by 3% magnetic with steel, and magnetic is strong, stable performance, the connected mode of rotor case and magnetic ring body also can be bonding and forms, and this mode has the advantages that magnetic field is strong, save material, reduce the cost.
