A Novel Structure for Minimization of Thrust Ripple on Voice Coil Motor Used in Ventilators
2021 13th International Symposium on Linear Drives for Industry Applications (LDIA), 2021This paper investigates a novel structure voice coil motor (VCM), which is used in ventilator. The VCM controls on and off of the valve of ventilator, so steady thrust and fast response are needed. The influences of structure parameters to the performance are investigated by finite element analysis.

Reduction of thrust ripple in Linear DC Motor
1995To design a LDM servo system, it is need to reduce thrust ripple for precise position servo system. The thrust ripples make it difficult to control in position servo system, we introduce some technique to reduce thrust ripple in LDM, and propose a technique to compensate the end effect in LDM by adding two sub magnetic pole.

Thrust Ripples Test and Analysis of Permanent Magnet Linear Synchronous Motor
2011 Third International Conference on Measuring Technology and Mechatronics Automation, 2011Thrust ripples are the main factors which affect the application and development of permanent magnet linear synchronous motor (PMLSM). In order to control and compensate the thrust fluctuations of permanent magnet synchronous motor, the mathematical model of thrust fluctuations must be established first.
