This technical specification deals with the steady-state operation of cage induction motors within the scope of IEC 60034-12, when fed from converters. It covers the operation over the whole speed setting range, but does not deal with starting or transient phenomena.
Only indirect type converters are dealt with. This type comprises converters with impressed direct current in the intermediate circuit (current source converters) and converters with impressed d.c. voltage (voltage source converters), either of the block type or the pulse controlled type, without restriction on pulse number, pulse width or pulse frequency. For the purpose of this technical specification, a converter may include any type of electronic switching device, for example transistors (bipolar or MOSfet), IGBTs, thyristors, GTO-thyristors, etc. with analog or digital control electronics.
