Calculation Equivalent of induction motors program

Calculation the equivalent circuit of AC induction motors program

REMCAD


The program is designed for users and designers of electric-motor
drives with AC induction motors powered by Frequency inverters.

DESCRIPTION OF THE PROGRAMThe RemCad program can be
used for:1.1 the storage of basic machine data1.2 the calculation
and drawing of the characteristics on the basis
of the Equivalent Circuit (Torque, PowerFactor, Efficiency,
InputPower etc.)1.3 The export of the calculated data
The calculation and drawing of the characteristics on the basis of
the equivalent circuitThe following characteristics are drawn and
calculated:- the Moment characteristic dependant on frequency
and current
(current being the parameter)- the PowerFactor characteristic
dependant on frequency and current (current being the parameter)-
the Efficiency characteristic dependant on frequency and current
(current being the parameter)- the InputPower characteristic
dependant on frequency and current (current being the parameter)
The calculation is performed on the basis of the equivalent circuit
of the asynchronous machine.
