We want controllers that are small and light - - the industrial controller shown is probably, what, about 4 x 6 inches in size? That's 24 square inches of circuit board. It's also attached to a large heat sink (not shown.)

So, that that industrial controller has a power density of about 400 watts per square inch. The Mamba Monster has a power density of about 1800 watts per square inch. Our newest controller, the Phoenix-ICE-HV-160 has a power density of about 3200 watts per square inch.

These power densities mean that the hobby controllers are under considerably higher stress than their industrial cousins.

The Boards shown in the pictures are 4" X 8" by themselves. By the time you include the casing and yes, the Large Heatsink attached to the rear, the complete controller grows to a size around 8" X 12", being around 6" thick.

We are headed toward this type of technology being included in our daily drives to and from work.

I WAS very excited about the announcement of GM's production of the Chevy Volt until I recently read they changed the setup.

In the beginning, the IC Engine/Generator was to kick on after the Battery was depleted to supply the drive motor AND recharge the Battery. After doing so, it would turn off, until the Battery was depleted again.

Somewhere between initial announcements and production, this scheme changed.

Now, the ONLY Battery travel is the first 40 miles. Then the IC Engine MUST run fulltime, until YOU recharge at home.

There is a sizing problem in this configuration.

Battery Technology is growing by leaps and bounds along with motor/controller Technology.

This first attempt by GM will be a flop unless they change the setup again not to mention they are already 10K outside of their target price.

A Better configuration, I believe, will be one that uses multipole brushless hub motors. 32 poles or more, that are housed inside what we know now to be the brake drum.

No Drivetrain. Direct 4 wheel drive. Independant Traction Control with a Computer over seeing everything.

I want to further my Education in this field.

I knew if there was a person that could answer my questions about this Industrial setup, it would be you Patrick.

I learn very much from your Posts.

Thank you for taking the time to share your insight with us.
