Electric Traction via rewound industial induction motor

Mark_T

I've been working towards using a rewound 2.2kW 3-phase induction motor
as a traction motor from low voltage (36V or 48V), using the Propeller to control the motor,
and a custom 3-phase MOSFET inverter bridge as power stage.

I've mentioned my progress on induction motor drive before, here:

I've also been converting an old 2.2kW industrial motor by refurbishing and rewinding for a
lower voltage, documented here: http://sphinx.mythic-beasts.com/~markt/motor-rewind/motor-rewind.html

Currently I'm in process of building a high-current inverter bridge, then the motor windings
will be reconfigured and tested properly, with LiFePO4 battery pack (currently 24V).

And here I was, thinking that winding a Coil for an AM radio was some kind of accomplishment...

What an awesome project! And a lot of work too.. What are you going to do with all that Traction?

Erm, that's a good question. Ideas are welcome

Well, there are many options for Traction Motors...

Could be a money making opportunity, Helping to support your wire habit.
