Burnt-out Currie BLDC controller

My old Currie ElectroDrive stuttered yesterday, then some of the magic smoke escaped from the controller area.

This is a very old one using a brushless DC motor and integrated controller.

I believe that repairing the controller is not really feasible, but that, with care, it can be removed making the phase and hall wires for the motor accessible.

Anyone done this and has documented the process? I have a couple of Crystalyte controllers and appropriate batteries (battery is 36V 13AH NiMH, controller is 20A) - might they be suitable as an external replacement? The original runs on 24V and I think it was rated at 24V - will the motor survive if I run the new controller at 36V?

The mechanics is in very good order, and it has run so well that I'd like to recover it if possible - I've not found anyone in the UK who actually holds stock of new motors - think they've changed a lot over the years anyway.

All help gratefully received...

I haven't done this but I see over on the Endless Sphere forum that people have done it with the Cyclone motors.
