A couple of small corrections...

It's not a "regulator", it's a resistor pack. It's not on the motor, but in the bottom of the chassis. It uses resistors to drop the voltage to lower levels to run the fan motor at a lower speed.
And most importantly, it's not a carbon crash structure. People often confuse that - it's simply a fiberglass crash structure that is made using black fiberglass 9or at least painted black. Beside the confusion caused by the black color, Lotus also developed a similar carbon fiber crash structure that is used on Aston Martins (Lotus makes it for them) - it's similar in appearance and works on the same theories as the fiberglass ones used in our cars.

The fan speed switch is not a rheostat. A rheostat varies the resistance depending on how much you turn it (think volume control). The fan speed switch is simply a four position switch (off counts as a position). Each switch position feeds the full 12 Volts to a separate input of the resistor pack (that's located at the bottom of the chassis behind the crash structure). The resistor pack reduces the voltage to three specific values to provide three different fan speeds.
By the way, the new resistor pack is improved. The original one is mounted at the bottom of the chassis (on the top side of the bottom). Water collects down there and when it gets deep enough, it "floods" the resistor pack and causes corrosion and causes it to fail. The new improved resistor pack is better sealed so that water cannot get into it (at least no easily) and it doesn't corrode as easily. But you still need to drill the four drain holes into the bottom of the chassis according to the Factory Service Bulletin.
