Research on Thrust Ripple of Aperiodic Transient Linear Induction Motors

2021 13th International Symposium on Linear Drives for Industry Applications (LDIA), 2021
Because 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), 2020
For 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.

Thrust Ripples Suppression of Permanent Magnet Linear Synchronous Motor

IEEE Transactions on Magnetics, 2007
The thrust ripples in permanent magnet linear synchronous motor (PMLSM) are mainly generated by the distortion of the stator flux linkage distribution, reluctance force due to the relative position between the mover and stator, cogging force caused by the interaction between the permanent magnet (PM) and the iron core, and the end effects.

A Thrust Ripple Suppression Method for Long-Primary Double-Sided Linear Induction Motors Based on Harmonic Current Injection

IEEE Transactions on Transportation Electrification, 2023
For the long-primary double-sided linear induction motor (LP-DSLIM) excited by the symmetrical current, there is a double slip frequency ripple in the thrust due to the dynamic longitudinal end effect.

Effects of different chopping modes on the thrust ripple of electromagnetic launchers

2012 16th International Symposium on Electromagnetic Launch Technology, 2012
Brushless DC linear motors have considerable advantages of simpler structure, higher efficiency, higher thrust density and so on. They are well suited for many domains such as electromagnetic launch and launch-assist, and their winding currents usually are square-wave.
