My Twike has an AC induction motor and the controller and charger are one unit the size of a toaster. It was built in 1998.
I wonder if they are using the motor-as-an-inductor trick? On an AC motor, running chopped DC through a winding won't make it run. In fact, it will make the motor lock up! That could be a safety feature, so the vehicle won't roll away while it is charging. :-)
I know that Alan Cocconi did this on some of his AC motor controllers. -- Any intelligent fool can make things bigger, more complex, and more violent.
