Phase-shift or pole-shift method can reduce the detent force of double-sided permanent magnet linear synchronous motor (DS-PMLSM) dramatically. However, this causes a decrease in thrust and an increase normal simultaneously. To overcome drawback, novel slot-shift structure whose slots on two sides primary component are staggered by optimal distance is proposed paper. The models including end cogging established theoretically, then verified finite element analysis. windings upper lower...
In order to improve the thrust density of electric actuator in aircraft, a double primary tubular permanent magnet synchronous linear motor is designed. By establishing magnetic circuit model, air gap and characteristics outer inner motors are analyzed. Considering that it works wide temperature range environment, multi-objective optimization carried out. The surrogate model established by neural network used simplify mathematical motor. average thrust, restrain fluctuation reduce difference...
In this paper, a neural network surrogate model is established to predict the average thrust and fluctuation of motor, multi-objective optimization motors in consideration temperature changes employed. The method utilizes efficient ability non-linear system establish relationship between structural parameters, for example, pole size, winding size yoke thickness, motor. used reflect influence various parameters on performance interval can be determined quickly. also applied motor...
In a wide temperature range environment, as the material properties changing with temperature, traditional permanent magnet motor has disadvantage of large variation electromagnetic thrust. view this situation, tubular synchronous linear is designed. The stability output thrust motors under NdFeB excitation or SmCo compared. Moreover, paper adopts convex-shape poles to reduce fluctuation, then composite combine NdFeB's high magnetic energy product SmCo's low coefficient, which meets...
