Description
Technical field
Technical field of motors is the utility model is related to, more particularly to a kind of new fixing groove disk type electric motor rotor.
Background technology
Disc type electric machine is also known as motor in axial magnetic field, and the First motor of faraday's invention in 1821 is exactly disc type electric machine.
But because the rotor of disc type electric machine has axial magnetic attraction, manufacture the shortcomings of complicated is also referred to as radial magnetic field by conventional motor
Motor is substituted.But conventional motor is due to " bottleneck " phenomenon of root portion, cause that the radiating of motor is bad, iron core utilization
It is low.These problems could be solved by changing only from structure.The interest of design of electrical motor engineer is transferred on disc type electric machine again.
Disc type permanent magnet synchronous electric motor has very high power density, small volume, in light weight, compact-sized and good dynamic property etc. excellent
Point.So as to which disc type electric machine turns into a kind of preferable drive device, at home and abroad developed rapidly.Rare earth permanent-magnetic material is in recent years
The development come and a key factor for promoting disc type electric machine permagnetic synchronous motor to study.It is continuous with permanent magnetic material performance
Improve and perfect, the particularly improvement of Nd-Fe-B permanent magnet material heat endurance and corrosion resistance and price gradually reduces, and also makes
The research for obtaining rare-earth permanent-magnet electric machine enters a new stage.
Recently as the continuous development of science and technology, exist between disc type electric machine stator-rotor iron core manufacture difficulty and electric machine rotor
This two big shortcoming of axial magnetic attraction is resolved by new processing technology and prioritization scheme, is excluded for further research
Obstacle so that all kinds of disc type electric machines get up using fast development.Rotor core surface is typically bonded in using permanent magnet, but
The shortcomings that being this traditional structure, is, in disc type electric machine running, the bonding magnetic steel being directly bonded is insecure, monoblock or office
Portion's obscission, makes motor operation great risk be present.Also useful monoblock pressing plate pushes down the mode of permanent magnet, and this structure
Shortcoming is that eddy-current loss is big in pressing plate, and because pressing plate has thickness, so as to increase the air gap of motor, influences the gas of motor
Gap magnetic is close and the utilization rate of permanent magnet.
