https://doi.org/10.4467/2353737XCT.15.041.3841In 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.

https://doi.org/10.4467/2353737XCT.16.254.6053The paper presents a special algorithm and software for the analysis of coupled electromagnetic-thermal phenomena in a squirrel cage induction motor. In the proposed model the nonlinearity of the magnetic circuit, the movement of the rotor, the skewed slots and the influence of temperature on electrical and thermal properties of the materials have been taken into account. In order to verify the developed algorithm and software, the startup process of the motor has been examined, among others. The results of computations have been compared to the measurements.
