Claim:
An electric motor vehicle comprising: (i) a chassis, (ii) at least one pair of integrated wheel and brushless DC electric motor assemblies mounted on the chassis using suspension components, (iii) a battery pack carried by the chassis and providing power to the integrated wheel and electric motor assemblies; and (iv) a control system for operating each said integrated wheel and motor assembly independently of each other integrated wheel and motor assembly, the control system comprising a master controller connected to the battery pack, and, a plurality of separate slave controllers connected to a battery pack, each slave controller being positioned on the vehicle adjacent to a corresponding one of said integrated wheel and motor assemblies and being connected to corresponding integrated wheel and motor assembly and to the master controller, the speed of each of the wheels being independently adjusted by a corresponding one of the slave controllers to rotate substantially at a speed requested by the master controller, wherein the speed of a first one of the wheels is adjusted by the slave controller corresponding to the first wheel to rotate substantially at the speed requested by the master controller, by adjusting power to the motor assembly of the first wheel, upon the first wheel starting to rotate slower or faster than the speed requested by the master controller.
