Comparasion Study On Permanent Magnet-type Blushless Motor Imtergreted Stater And Damper Used In Hybrid Vehicle

In this project, the electro-mechanical energy transformation part is the permanent magnet brushless motor. Through the comparison of various based permanent magnet brushless and AC induction ISAD system, it is of practical significance for the choice, application, volume production of ISAD system.It is researched for a ISAD system based permanent magnet brushless motor from theory to practice in this project. Firstly, The model and of permanent magnet brushless motor used in hybrid vehicle was designed for transient performance simulation and analysis in this paper. A drive control system model of Integrated starter and damper (ISAD) was also designed for the performance analysis and its hardware circuit based FPGA was supplied. Secondly, Two cases were compared between square and sine wave permanent magnet brushless motor to test their ISAD performance. And then, Through the simulation and analysis of a hybrid vehicle model in used ISAD, the parameters for the electrical power was given by the 1.8L engine + ISAD system in order to meet the same acceleration performance of 2.5L engine. Next, the models of permanent magnet brushless motor and AC induction motor used in hybrid vehicle was designed for transient performance simulation and comparasion , a result was certificated in the end through the comparison of hybrid vehicle and conventional vehicle.
