This paper improves the traditional lumped parameter thermal model by adding compensation elements under a Canned Switched Reluctance machine. The verification by FE method shows high accuracy of this model. The sensitivity analysis, including the cooling effects and winding uncertainty is discussed. This proposed method requires little computation time and is suitable for thermal design of different...
In this paper, a robust switched reluctance motor (SRM) drive using the speed closed-loop with the discrete time reaching law control and the current closed-loop with nonlinear conversion function from torque to average current is proposed. Firstly, the current closed-loop is implemented by employing the average value of three phase-currents and the digital proportion and integrator, which greatly...
This study presents a control scheme to continuously estimate the rotor position and speed of sensorless switched reluctance motor (SRM) drives. The estimation model is based on the two-dimensional (2D) least squares technique. For the proposed estimation scheme, only the rotor position to the optimal sensing phase being the active phase via measuring the current and the voltage is estimated. Furthermore,...
This paper deals with the design of switched reluctance motors (SRM). The effects of different parameters on the design are investigated. Finite element method is used to predict design and performance parameters. Useful conclusions are drawn as to optimum configurations for switched reluctance motors
