Exro Technologies

EXRO has developed a fundamental new approach to electric generator and motor design. Its DCM technology senses changes in input energy and load, and then optimizes the motor or generator by intelligently reconfiguring the inductors. In essence, it’s Dynamic Current Management (DCM) creates a multiplicity of design points for each motor or generator. It’s like having multiple power curves in a single machine. The end result is electric motors and generators converting energy more efficiently across a wide and fluctuating range of speed and torque.

As an example, portable generators are challenged to adapt to changes in load and consume more fuel than should be required for a given electrical output. This is due to the single high efficiency operating point of the electric generator. When EXRO’s technology is integrated, less torque is needed for rotation because the generator’s increased efficiency creates a more appropriate induction process and thus a more efficient energy conversion at any speed or torque. As a result fuel consumption can be minimized in the power conversion chain.

EXRO’s technology will benefit hybrid and electric vehicles. DCM will provide better motor and generator performance by integrating several switch points that establish additional peak operating points through reconfiguration of the inductors. In brake mode, it will more efficiently convert mechanical to electrical energy. When accelerating, the technology will more efficiently convert electrical energy back into “rotational” torque, creating a more efficient electrical system that will reduce fuel consumption. The end result will provide greater improvement in overall mileage-range in more variable conditions and city driving.

No two applications are identical, but in high variability applications DCM can be expected to deliver a significant improvement in system efficiency. The higher the variability, the greater the improvement. Whether that efficiency translates into improved generator efficiency, greater mileage/range for electric, hybrid vehicles or higher output for wind and wave power, the net effect is an improvement to the economics of the entire system.
