Abstract: A control system for motors, generators and other electric machines that improves machine performance by dynamically adapting to changes. These changes may be in user inputs, machine operating conditions and/or machine operating parameters. The control system can take advantage of more independent machine parameters. That gives greater freedom to optimize and allows motors and generators to perform better than bigger, heavier machines, particularly more efficiently. The control system is software-based. So standard interfaces allow the control system to be improved and updated without changing hardware. This adaptive control system improves performance in a wide variety of motor and generator applications, particularly those that need high efficiency over varying conditions.

Abstract: Disclosed is a propulsion system for an electric car or other vehicle with potentially better performance—power, efficiency, range—than a gasoline vehicle, at a competitive cost. The motor control system can dynamically adapt to the vehicle's operating conditions (starting, accelerating, turning, braking, cruising at high speeds) and other inputs and parameters. That consistently provides better performance. Isolating the vehicle's motor or generator electromagnetic circuits allows effective control of more independent parameters. That gives great freedom to optimize. Adaptive motors and generators for an electric vehicle are cheaper, smaller, lighter, more powerful, and more efficient than conventional designs. An electric vehicle with in-wheel adaptive motors delivers high power with low unsprung mass and high torque and power-density. Total energy management of the vehicles entire electrical system allows for large-scale optimization.
