Permanent magnet assisted synchronous reluctance motor, design and performance improvement

摘要: Recently, permanent magnet assisted (PMa)-synchronous reluctance motors (SynRM) have been considered as a possible alternative motor drive for high performance applications. In order to an efficient drive, performing of three steps in design the overall is not avoidable. These steps are optimization of motor, identification parameter and implementation advanced control system ensure optimum operation. Therefore, this dissertation first deals with optimization Permanent Magnet Assisted Synchronous Reluctance Motor (PMa-SynRM). Various key points in the rotor low cost PMa-SynRM introduced their effects studied. Finite element approach has utilized show these parameters on the developed average electromagnetic torque total d-q inductances. As it can be inferred from name there some magnets mounted the rotor core. One features the magnetization core using stator windings reduce manufacturing cost. At next step, discussed. Variation of motor due temperature airgap flux reported literatures. Use off-line models estimating known a computationally intensive method, especially when include effect of cross saturation. Therefore practical applications, on-line estimation is favored achieve high performance control system. dissertation, simple practical method introduced. Last part presents one advanced strategy which the introduced estimator. A Maximum Torque Per Ampere (MTPA) control scheme along simple estimator introduced. This capable maintaining MTPA condition stays robust against the variations parameters. Effectiveness procedure validated by presenting simulation experimental results 1.5 kW prototype PMa-SynRM, designed manufactured through method.
