Abstract:
This thesis considers the development of a variable speed drive motor based on the Switched Reluctance Motor (SRM) 8/6 for an application in an automotive air-conditioning (A/C) system. A complete A/C system model + cabin in Matlab-Simulink are established to study the performance in a refrigeration cycle. It is complemented by the inclusion of a SRM drive model, designed particularly for the application. We present a set of guidelines for the development and application of the SRM when operating at 42V. This means to take into account the effects of magnetic saturation of the material (Imax=65A). The nonlinearities of the machine are developed modelling the nonlinear characteristic flux-current-rotor position (-i-θ) and electromagnetic torque (T-i-θ), for which it has used commercial software of electric machines design. The SRM drive uses a speed/torque control; besides the temperature control in the cabin utilizes a fuzzy control. The validation uses a similar feature motor with different load points.
