Performance Calculations on Induction Motors Practical Straightforward Means for Calculating Performance of Single-Phase or Polyphase Induction Motors

Practical means for calculating the performance of both single-phase and polyphase induction motors from previously determined constants are developed in a straightforward manner. The methods are suitable for accurate calculations but can be simplified for approximate calculations. The methods given are complete and no auxiliary charts or sets of curves are required, nor need any diagram be constructed. The single-phase calculation method is based on the cross field theory presented by H. R. West. The polyphase calculation method is based on the equivalent circuit.
