| Abstract: | Application of the linear motor to the machine tool is introduced as well as the prospect. A contrast between the numerically controlled linear motor system and the ball bearing screw pole system is made,and the advantages of the numerically controlled linear motor system are pointed out. On the basis of analyzing the characteristics of the linear motor,the leading problems in the design and application of the linear motor are given as follows: the design of magnetic way, the means of control and the blue point of cooling system. Finally, an example of the application of the linear motor to the irregular surface turning of piston is given. |
