Line start synchronous motors (LSSM) have been recently introduced in the motor market to meet new efficiency class requirements. They exhibit high efficiency and power factor compared with induction motors. On the other hand, the difficult design, manufacture, and high cost due to the presence of permanent magnets limit their widespread use in the market. Another key factor that limits the LSSM diffusion...
The paper deals with minimization of supply power and energy for induction motor (IM) based on maximal torque per ampere (MTPA) strategy. The article describes two MTPA algorithms. Firstly such algorithm is proposed for IM model of which doesn't take iron losses into consideration. Subsequently the second algorithm is based on the model of IM, which respects iron losses. Both algorithms are realized...
