Rotating Electrical Machines - Part 17: Cage Induction Motors When Fed from Converters - Application Guide
|Publication Date:||1 June 1998|
|ICS Code (Motors):||29.160.30|
This technical report 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 (I-converters) and converters with impressed d.c. voltage (U-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 report, 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.
