Abstract
The utility model discloses a rotor of a permanent magnet motor, which comprises a hollow shaft, a rotor iron core, magnetic steel, a magnetism isolating copper ring, a magnetism isolating copper plate, a positioning ring and an elastic retaining ring for a shaft, wherein keys of the rotor iron core and the magnetism isolating copper plate are jointly and symmetrically assembled with a key slot of the hollow shaft, two ends of the rotor iron core respectively press the magnetic steel for magnetism isolation by using the magnetism isolating copper ring and the magnetism isolating copper plate, and a deweighting block is simultaneously provided for calibrating dynamic balance of the rotor. In addition, the positioning ring is press-mounted on the hollow shaft through interference fit. The magnetism isolating copper plate is used for limiting the rotor iron core below the positioning ring. The elastic retaining ring for the shaft is additionally mounted on the outer side of the positioning ring. The rotor can use the mechanical processing way to ensure the dimensional tolerance, be easy for processing and manufacture and lead the degree of product consistency to be high.
Description
Technical field
The utility model relates to a kind of permanent magnet machine rotor, relates in particular to the silicon steel sheet fixture of p-m rotor.
Prior art
The electric rotating machine that possesses the rotor of permanent-magnet structure now has been widely used in the drive motors of hybrid vehicle and pure electric automobile.Electric machine rotor iron core adopts methods such as riveting, button, bolt, weldering, bundle to be laminated into generally speaking, and above method is to being difficult to balance on the cost of manufacture of rotor and the product quality, therefore need one simple, structure make things convenient for permanent magnet machine rotor to make reliably.
Summary of the invention
The utility model is achieved through the following technical solutions: a kind of permanent magnet machine rotor comprises hollow shaft, rotor core, magnet steel, every the magnetic copper ring, every magnetic copper coin, locating ring, circlip for shaft.The wherein keyway symmetry assembling of rotor core and and hollow shaft common every the key of magnetic copper coin is to overcome play to axial.The rotor core two ends are used respectively every the magnetic copper ring with every the magnetic copper coin and are pushed down magnet steel, reach the effect every magnetic on the one hand, also provide deweighting block for the school rotor dynamic balancing simultaneously.In addition, press-fit a locating ring on hollow shaft, this locating ring inner ring and hollow shaft included position adopt interference fit.Every the magnetic copper coin rotor core is limited in below the locating ring.Install circlip for shaft additional in the locating ring outside.Preferably, above-mentioned circlip for shaft is a stainless steel material.Preferably, above-mentioned locating ring and hollow shaft are fixed by using hot jacket pressure assembly method.
Locating ring and rotor are in relative static conditions during motor rotation, have avoided other complicated processing technology to cause the not high problem of consistency of rotor, have reduced the motor cost of processing simultaneously.Rotor at it axially by reaching every the magnetic effect every the magnetic copper ring with every the magnetic copper coin, repulsion that its suffered axial force mainly is a magnet steel integral body in the rotor core and slight silicon steel plate stacking repulsive force, but this repulsion sum is much smaller than the extrusion pressure of interference fit between locating ring and the hollow shaft, thereby prevents the problem that comes off of permanent magnet effectively.Add a high-strength stainless steel circlip for shaft in the locating ring outside, more improved the reliability of this novel permanent magnetic rotor.The utility model principle is simple, is easy to assembling.Can use the machining mode to guarantee dimensional tolerance, processing and fabricating is easy.
