Current in Rotor Bar (Induction Machine) Magnetic Transient 2D

Clement Junior KENDEG ONLA

Hello,

Please, how is the current value calculated in rotor bars (solid conductors) using Magnetic Transient 2D Study? The EMF is obtained by differentiating the flux with respect to time. However, it is unclear which formula is used to obtain the current in the rotor bars (solid conductors) in Flux Software. Dividing the EMF by the resistance of the bar was attempted, but it did not match the result from Flux.

Hello Clement;

 

In Flux, the quantities are computed according to Maxwell equation, in AC Steady state the current density is computed as you can see from this help extract:
