Abstract The designs and working principle of electric spindles、bearing technical as well as crucial technology and so on was introduced in this paper.Electrical spindles is being made by a direct motor rotor of be hollow pack in main shaft on and stator knows super-cooling but cover fixes, which form a complete unit of main shaft in the casing hole of main shaft, and then the electricity rotor directly drive the operation of main shaft.Its main application is being compound process machine tool and much axle to unite to move, polyhedron processing machine tool and the machine tool of parallel connection in.This design cut the related knowledge of central fuselage according with requirement through using network tool and magazines , each kind of periodical and the books in the library and then determining the design, which satisfies the needs.The design method is as follows: First, look up information to produce the basic thought of the electrical mechanical design of main shaft, determine the reasonable electrical structure of main shaft.Then, the key axle for electrical main shaft is designed, and analyze and choose the match for bearing, the electrical bearing of main shaft choose to match principle have determined;Use related knowledge finally fully press requirement for this program carry out specific design.The method of designing adopted the scheme theoretical design and experience design, and the data sources utilized was adequate content extensively.Feasibility of realize the scheme is high.Practice shows that the MS24015 main shaft of milling machine design satisfies the request.Keywords : Electrical main shaft Stator Rotor Crucial technology Dynamic balancing
