Recharge battery by induction on simulink

Hi, I'm trying to simulate an electric car powered by induction with Matlab Simulink. I already have the scheme of the car, I only have to change the power source. I have to "send" the electricity from under the road and the car "receive" the power over the road. I don't really know how to do it w/ Simulink... Here is a capture of my file http://image.noelshack.com/fichiers/2014/49/1417770877-capture-matlab.png I surrounded the part which is certainly the cause of the error displayed when I launch the simulation : "Number of variables exceeds number of equations. Check for missing reference node.". At the moment if want to omit the battery of the car : I want the electricity to go directly to the motor. When this problem will be fixed I'll consider adding battery. Ask me for the original file is you need is. Thank's :-)

Hello, Titouan,

Please try inserting an electrical reference block on the right hand side of your magnetic circuit. It needs a reference on both sides of it for the system of equations to be consistent.

Best regards,

Javier

Hi, Did the model work after this modification please? I'm working in the same project and I have this problem too. Thank you,
