RESEARCH ON MODEL OF A NEW SHORT-STROKE LINEAR MOTOR AND ITS EXPERIMENTS

The special structure and working principle of a novel short stroke linear DC motor with permanent magnets are presented. Based on it, using theory analysis method with practice application to deduce the coupling relation between mechanical and electromagnetic equations, establish a mathematical model, analyse the parameters affecting the motor dynamic performance and show the block diagram of the linear motor model and transform functions. In order to evaluate its performance and derive its quantitative mathematical model, the model parameters were tested and analyzed, the experiments of the short stroke linear motor was given, experimental results were verified by model equations. These show its effectiveness.
