Design a Line Start synchronous Motor and Analysis Effect of the Rotor Structure on the Efficiency
The line start permanent magnet motor (LSPMM)
combines a permanent magnet rotor for a better motor efficiency
during synchronous running with an induction motor squirrel cage
rotor to permit the motor starting by direct coupling to power source.
In this paper effect of the rotor structure on a line start synchronous
permanent magnet motor (LSPMM) is analyzed. LSPMM motor with
three different structures for rotor is designed by using RMxprt
software; efficiency and line current of LSPMM motor for different
structures in full-load condition have been presented. The results
indicate that with correct choosing of rotor structure, maximum
efficiency can be found.
