Description
Technical field
The utility model relates to a kind of electric machine rotor iron core.
Background technology
The rotor of general cage induction motor is to be made of the rotor conductor of generation torque under the interaction of electric current of being inducted by stator coil and flux and the magnetic rotor core that flux passes through.Rotor core is made up of the circular silicon steel plate of stacked multi-disc, and these silicon steel plate peripheral parts have a plurality of rotor, and these rotor are inserted high aluminium of conductivity or copper metal and formed rotor conductor with radial distribution in rotor.In addition, the two ends of rotor conductor have the end ring that connects rotor conductor formation loop separately, and the general pressure casting methods of aluminium that adopt of rotor conductor and end ring form more.The rotor of this structure needs magnetic is inserted in the core slots of rotor on the one hand, is not easy to make; Also there are some leakage field phenomenons on the other hand at the magnetic bridge place.
Summary of the invention
The purpose of this utility model is to provide a kind of electric machine rotor iron core, and this product can effectively prevent leakage field, improves efficiency of motor.
Of the present utility model being characterised in that: a kind of electric machine rotor iron core, comprise the circular ring type that is overlapped into one vertically chip unshakable in one's determination, described circular ring type chip unshakable in one's determination is made of the lug that the circumference perimembranous outside has the circular arc limit, the inside portion of described lug has the aluminium casting every magnetic bar installing hole, be provided with a pair of groove of inlaying in order to the rectangle magnetic stripe between the two adjacent lugs, the middle part of circular ring type iron core is provided with driving sleeve, be provided with aluminium casting magnetism-isolating loop between described driving sleeve and the circular ring type inner edge portion unshakable in one's determination, described aluminium casting magnetism-isolating loop is crossed the aluminium that having in the radial direction of rectangle magnetic stripe center contact with the rectangle magnetic stripe and is cast every the magnetic raised line, the casting of described aluminium contacts every magnetic raised line the inner with the rectangle magnetic stripe, the outer end of described rectangle magnetic stripe be provided with between two adjacent lugs every the magnetic fracture.
Advantage of the present utility model is: be provided with aluminium casting magnetism-isolating loop, aluminium casting every the magnetic bar and every the magnetic fracture, can effectively avoid producing along rotor core leakage field or magnetic flux in the radial direction, guarantee that the magnetic flux that produces is tangential direction, effectively improves the operational efficiency of motor.
