The principle of linear electromotor and classification

From;  Author:Stand originally

Alleged and linear electromotor uses electromagnetism action principle namely, change electric energy the equipment of sharp movement kinetic energy directly. In actual application, to assure to be in whole journey primary with sub the coupling between keeps changeless, want commonly will primary with sub make different length. Linear electromotor and rotate electromotor is similar, after connecting three-phase electric current, also can produce magnetic field in air gap, if take no account of the effect that carry a department, magnetic field shows sine to distributing in linear direction, just this magnetic field is translation do not rotate, because this calls travelling wave magnetic field. Travelling wave magnetic field and sub interaction produce electromagnetism thrust, this is the fundamental that linear electromotor runs. Because linear electromotor is mixed,rotate existence above correspondence concerns between electromotor, because this rotates every kinds,electromotor has corresponding linear electromotor, but the configuration of linear electromotor is compared rotate electromotor is more agile. Linear electromotor can divide by working principle for: Linear dc electromotor, linear induction motor, linear synchronous electromotor, linear pace enters the electromotor, linear electromotor that suppress report and linear magnetoresistive electromotor: Can divide by configuration reach cylinder form for form of flat type, U.
