Abstract: The paper focuses on the analysis of the asynchronous torque of the
line start permanent magnet synchronous motor (LSPMSM) with the asymmetrical
squirrel cage winding. In order to calculate the asynchronous torque the
parametrical field-circuit models of LSPMSM have been elaborated on. Further,
the models have been applied to investigate the impact of squirrel cage
asymmetry on the asynchronous torque. The evaluated asynchronous torque vs.
rotor speed characteristic of proposed motor with asymmetrical cage has been
compared with the characteristics of reference asynchronous motor and LSPMSM
with symmetrical cage winding. It has been found that deepening of chosen bars
of the cage improves the starting properties of the LSPMSM.
