Porównanie napędów z silnikiem indukcyjnym dwufazowym i trójfazowym z litym rdzeniem wirnika

The article presents researches results of one-phase drivers equipped with two- and three-phase induction cage motors with solid rotor core. The motors have been constructed on the base of typical three-phase induction cage motor with two-poles and shaft height 90 mm. Typical sliced core was removed from shaft and replaced with solid core. The solid rotor was tested in two- and three-phase stators of experimental motors powered from electronic inverter. There are presented comparative researches results of drivers at continuous work with decreased load due to highest temperature growth and torques characteristics at different frequency. All comparisons were preformed for several air gap value.
