Abstract
Linear motion applications are more demanding than ever before. A traditional linear motion involves an intermediate element that converts the turning motion of rotary motor into straight line travel. Linear motor can drive a linear motion load without intermediate gears, screws, bearings or crank shafts. Linear motors with permanent magnet are among the best candidates for applications requiring high acceleration, high speed and high precision. However, permanent magnet usage such as Neodymium Iron Boron (NdFeB) has led to increment of material cost due to the fluctuate price of rare earth material problem. According to the requirement of the application environment and motor performance, the alternative solutions such as electromagnet have recently become popular. Switched reluctance linear motor (SRLM) has been an attractive alternative for linear motion systems due to the simple structure, low starting current and mechanically robust. In order to overcome the issue of SRLM on low thrust, the optimization of some important parameters will influence the inductance and magnetic flux. Thus, the study covered the variation of three parameters which are air gap length, δ, teeth pitch,τp and teeth ratio, wt/τp. The parameter has been varied for every SRLM’s model in order to observe the effect of the SRLM when the test is carried out. In this design, Solidwork software is used to modelling the SRLM. The static characteristics of the SRLM are calculated using a finite element method analysis (FEM) which capable of predicting the SRLM thrust to analyse the SRLM performance. The performance of every model has been compared. The SRLM model with optimal performance according to the parameter configurations is when the air gap length, of 0.1 mm, 4 mm teeth pitch and 0.4 teeth ratio, where the thrust reaches 51 N when 1.0 A current is applied. In conclusions, every parameter contributes to increasing the value of thrust. The thrust increase when the airgap decrease and the thrust also increase when the pitch increase. The smaller percentage of teeth ratio also affects the thrust increase. Finally, maximum performance of SRLM models with appropriate combination size of parameter has been exposed as a guideline to other researcher. In future, it is recomended to study the functionality of dynamic characteristics of SRLM by developed the motor drive system to enhance the performance of SRLM motor.
