Thrust Ripple Analysis on Toroidal-Winding Linear Permanent Magnet Vernier Machine
IEEE Transactions on Industrial Electronics, 2018Linear permanent magnet Vernier machines (LPMVM) have received more and more attention in recent years due to the advantages of high thrust density and low thrust ripple, which are both required in many direct-drive applications. In this paper, a double-sided toroidal-winding LPMVM (DSTWLPMVM) is proposed, and the thrust ripple sources for this type of

Research on Thrust Ripple of Aperiodic Transient Linear Induction Motors
2021 13th International Symposium on Linear Drives for Industry Applications (LDIA), 2021Because of its simple structure, linear induction motor(LIM) is widely used in rail transit, precise positioning, and electromagnetic emission. Due to the dynamic longitudinal end effect, the distribution of the magnetic field is distorted. As a result, the axial thrust of the motor fluctuates twice the power supply frequency.

Thrust Ripple Influence of Fractional-Slot Permanent Magnet Linear Motors
2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2020For permanent magnet linear motor (PMLM), the thrust ripple is bigger compared with the conventional rotary motor, which deteriorates the thrust performance. Based on FEM, the influences of thrust ripple are investigated including slot/pole combination, magnetic load, electric load and end tooth.
