Double Cage Equivalent of Deep Bar Rotor Motor

[hvcad]

I have a set of parameters for an induction motor with a deep bar rotor. This includes the starting and running values of the rotor single cage equivalent circuit.

Can any body advise me of a straightforward method of converting these parameters to the resistance and reactance of a double cage induction motor, which has a torque speed curve similar to that of the deep bar machine. I've been getting tied up in the maths, and I suspect that somebody must have done this before now.
