|Abstract in different language:
|In many economic units where only single-phase voltage is available arises the need of using the induction motors of the power in the range to 5kW. Standard single-phase motors of such a power in practice do not exist. Therefore, the paper presents and analyses the possibility of replacing the typical single-phase engine with a standard three-phase induction motor for purposes of driving the devices. The three-phase motors of large power and speed range are commonly available. Their application with singlephase supply is practically feasible and usually remunerative, as a three-phase supply system with small value of ordered power is more expensive and its wiring more complicated. Three-phase motors provided with stator winding and capacitor may be used under single-phase supply for driving small-power devices (ranging to watts) and high-power ones (e.g. in railway vehicles supplied from AC contact line).
