Compared analysis of lspm sm and squirrel-cage motor exploitation with variable rotational speed
Languages of publication
In this paper, the steady-states operation of a line start permanent magnet synchronous motor (LSPMSM) and a squirrel-cage motor have been compared. The stator of a Sg 100L-4B type, 3 kW induction motor, was used in both structures. The squirrel cage in the rotor of the LSPMSM is made from copper. The influence of the frequency change of the supply voltage on the motor’s efficiency and current as well as the power factor has been examined.
