There's a body of work on asymmetrical three phase motors but it's not something with which I am fimiliar. I've appended a paper on the general theory.

In this scheme the AC voltage is applied between the two highest impedance points (black to green) and the capacitor goes to the lowest impedance (eg from green to blue/red). What you do if the motor turns backwards I don't know.
