Future energy challenges, likewise the environmental crises such as fossil fuel emissions
and global warming urge the world to focus on energy saving programs more than ever. An …

This article covers the design methodologies and optimization techniques studied in the
performance improvement of line-start permanent magnet synchronous motors (LSPMSMs) …

Electric Motors in Industrial applications consume between 30% and 40% of the generated
electrical energy worldwide. In the European Union (EU), electric motor systems are by far …

This paper presents a successful design of a high-efficiency small but novel interior
permanent-magnet motor using NdBFe magnets. It is designed to operate both at line and …

We present a new scheme to improve the starting torque and synchronization capability of
line-start permanent-magnet motors based on pole changing winding. Pole changing at start …

This study presents a comprehensive analytical analysis of line start permanent magnet
(LSPM) synchronous motors in both steady‐state and transient domains. The PM flux, the …

This paper proposes a design procedure in addition to some optimal design guidelines for
line start permanent magnet (LSPM) motors, independent from their ratings. Major transient …

In this study, wide overview of the existing line start permanent magnet synchronous motors
literature is presented. The treatment of the subject has been effectively sub‐divided in to …

This paper presents a design of a line start permanent magnet (PM) synchronous motor
capable of operating in two different synchronous speeds without requiring a drive unit. The …

Pole-changing of line-start permanent magnet motors at start-up has many advantages and
improves starting torque, synchronisation capability and steady-state performance …
