Collected scientific works of Ukrainian State University of Railway Transport, 2022 The asymmetry of the supply voltage adversely affects the operation of electricmotors, in particular induction ones. With an uneven load of the phases of the network, the voltagebecomes asymmetric - unequal between the individual phases.

New 5-Phase Concentrated Winding Machine with Bi-Harmonic Rotor for Automotive Application [PDF]
, 2014 For a power range from 10 to 30 kW, 5-phase machines are well adapted to low-voltage (48V) supply thanks to their reduced current per phase. For three-phase machines but with higher voltages (>120V), machines with a number of slots per pole and per phase
