Abstract
High precision linear machining tools is one of interesting research field in related to high qualitative products which is also becoming one of competitive factor. The movement precision can be affected by existence of ripple force, unpredicted external load and frictional force. The existence of cogging force is the one limited factor of the linear precision. The reduction of cogging force of its linear movement precision of machining tools using rotary motor drive can be obtained by the skewed rotor or implement the feedback control system. Many researchers have conducted the reduction of cogging torque of its machining tools drive supported by using a feedback control algorithm variation concepts. Because of the great opportunity of construction variation in linear motors, this paper proposes to investigate an innovation of the cage secondary Double sided linear induction motor construction aimed to obtain the zero cogging Force. The cogging force can be predicted by investigated of the variation of stored energy magnetic in the air gap. Therefore, at first in this paper the implementation of estimation flux path in multi-tooth model in which is built as similar construction to the cage single sided linear induction motor, and will be verified by building experimental multi-tooth test-bed. Based on that multi-tooth experiment and the justification of estimation flux path method, the double-sided linear induction motor with offset position between both sided will be developed with the assumption that the cogging force will be able to cancel each other. In this paper will be described the arrangement of LIM model using FEM software and simulated. This motors consist of two layers, moving and stationary part. The stationary part are arranged as the cage-ladder structure.
