electrical.theiet.orgConsider a single-phase induction motor. If the motor presented a purely resistive load to the supply, the current flowing would be in-phase with the voltage. This is not the case. The motor has a magnet and the magnetizing current is not in phase with the voltage. The magnetizing current is the current that

www.tecowestinghouse.comT he main circuit must be correctly wired. For single phase supply use input terminals (R/L1, T /L3) and for three phase supply use input terminals (R/L1, S/L2 , T /L3). Terminals U/T1 , V /T2 , W/T3 must only be used to connect the motor. Connecting the input supply to any of the U/T1 , V /T2 or W/T3 terminals will cause damage to the inverter.
