The linear motor primary part is connected to the power supply to produce a magnet field. By changing the current phase in the coils the polarity of each coil is changed. The attractive and repelling forces between the coils in the primary part and the magnets in the secondary part cause the primary to move and generate a linear force.
Construction of AC Servomotor. We have already said in the beginning that an ac servomotor is regarded as a two-phase induction motor. However ac servomotors have some special design features which are not present in normal induction motor thus it is said that two somewhat differs in construction.
