Information

This class produces a three-phase voltage system to variable-frequency control of an asynchronous motor.

The output voltages constitute a three-phase system of quasi-sinusoidal shapes, created according to the following equations:

Wel=Wmecc*PolePairs+DeltaWel

U=U0+(Un-U0)*(Wel)/Wnom

where:

  • U0, Un U, are initial, nominal actual voltage amplitudes
  • Wmecc, Wel are machine (mechanical) and supply (electrical) angular speeds
  • PolePairs are the number of machine pole pairs
  • DeltaWel is an input variable and depends on the desired torque
