The line-starting performance and synchronization capability of a line-start interior permanent magnet synchronous motor (LSIPMSM) has to be evaluated by considering different loads and different values of supply voltages, which requires the usage of a reliable dynamic model. In this work the parameters of a LSIPMSM dynamic model were determined by the differential evolution (DE). The optimization objective was the best possible agreement between the measured and by the model calculated time-behavior of model variables (responses of currents and motor speed).

The work presents a FEM-based design and analysis of interior permanent magnet synchronous motor with flux barriers (IPMSMFB), which can not be found elsewhere in literature. Various parameters of IPMSMFB rotor structure were taken into account at determination of a suitable rotor construction. On the basis of FEM analysis the rotor of IPMSMFB with three-flux barriers was built. Its flux weakening performance was compared to performances of the conventional interior permanent magnet synchronous motor, having the same rotor geometrical dimensions and the same stator construction.

The work presents the performance comparison of three- and single-phase line-start interior permanent magnet synchronous motors (LSIPMSMs) and induction motors with equal squirrel-cage design and symmetric four-pole stator windings for the first time. Motor performances were directly compared and evaluated, thus emphasizing impacts of the permanent magnet breaking torque and reluctance breaking torque on the LSIPMSM performance in the asynchronous operation region.

The work presents the impact of the rotor and stator slot number combination on the characteristics of induction motors (IM). The adequate choice of the former combination, the stator winding and skewing either the stator or the rotor represent the main measures for suppression of the undesirable effects of parasitic torques, which cause torque-dips in IM characteristics. These may cause that the motor does not reach its rated speed. Of course, all cage IM line-start performance degrading effects are also present in drives with line-start interior permanent magnet synchronous motors.

The paper presents a performance evaluation of a synchronous reluctance motor in BLDC drive. The tested synchronous reluctance motor was made from IEC 56 induction motor stator and four pole rotor with three-barriers per pole. Measured motor characteristics of the tested synchronous reluctance motor in the BLDC motor drive with 120 electrical degree conducting mode in the range of speed 4000 rpm through 10000 rpm are presented.
