The motor of the second structure, because stator is directly fixedly connected with rear end cap, therefore reasons such as the became unevens of stator silicon steel plate, will cause the length dimension variation of motor very large, Motor Shaft size be difficult to guarantee and temperature rise higher.In addition, front and rear cover also will cause not parallel because of the not parallel of stator core, thus causes bearing noise on the high side.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides a kind of production process few, and technique is simple and Motor Shaft dimensional uniformity is good, and temperature rise is little, and the permanent magnet motor that bearing noise is little.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of permanent magnet motor, comprise casing, the front end housing being coaxially arranged at casing both sides and rear end cap and be arranged at the stators and rotators of chassis cavity, described front end housing and casing are wholely set, the periphery of described stator and the internal face interference fit of casing, described casing is matched by seam with between rear end cap; Respectively be provided with a bearing in described front end housing and rear end cap, two coaxial bearing are arranged, the inner chamber interference fit of described rotor and two bearings.
The internal face of described casing is provided with the chassis cavity stator heating jacket shelves for stator heating jacket.
Described front end housing or casing or rear end cap are provided with flange seam and plane.
The arranged outside of described rear end cap has control assembly and the tension disc be arranged at respectively outside control assembly and back cover.
The arranged outside of described rear end cap has the mounting platform installed for control assembly.
The side that described casing contacts with rear end cap is coaxially arranged with recessed seam, and the inner side of described rear end cap is provided with the male half coupling matched with recessed seam.
Respectively be provided with a bearing chamber in described front end housing and rear end cap, in each bearing chamber, all place the jump ring that described bearing is located by a described bearing and an energy.
After the utility model adopts said structure, above-mentioned front end housing and casing are wholely set, therefore at production line, a secondary mould can be adopted, utilize moulding press the casing with front end housing integrally can be carried out shaping, thus production process is few, technique is simple, reduces technology difficulty, enhances productivity, and reduce production cost, improve the competitiveness of product in market.In addition, above-mentioned rotor is fixedly connected with two coaxial bearings arranged, simultaneously, between rear end cap with casing, seam coordinates, thus can guarantee the consistency shaft size, avoids the problem of stock or the product rejection caused because of casing buying or stator silicon steel plate became uneven, thus reduce Parts Purchasing quantity in motor production, reduce purchase cost, enhance productivity, further increase the competitiveness of product in market.
