N2 - Synchronous reluctance motors (SynRM) have drawn significant attention recently due to their advantages of no rotor copper loss, high efficiency and high reliability. The SynRM is often controlled with sinusoidal current and is equipped with distributed winding [1]. This implies that the end turn inductance should not be ignorable in the design and analysis as this would result in the phase inductance being underestimated and thus the power factor of the SynRM being overestimated. To accurately evaluate SynRM in the design stage, the 3-D finite element analysis (FEA) would be suggested [2]; however, it takes much computing effort and is time consuming. 2-D FEA is fast and is usually considered to be sufficiently accurate for analysis of many types of electric machines. However, this digest discovers that 2-D FEA may introduce significant errors in power factor calculations for SynRM due to the omission of end turn inductances.
