Exro Technologies Inc. Information

Our vision is to become synonymous with advanced, dynamic optimization and control of rotating electric machines. Our mission is to create a new global standard in advanced, dynamic optimization and control of rotating electric machines that provides economic benefits to users, competitive advantages to suppliers, and a cleaner environment for everyone. Exro has developed and patented a technology for self-optimizing electric motors and generators to improve efficiency in applications with high variability. Our technology can be integrated into existing applications, or designed with OEMs to create new custom designs that maximize economic performance. By developing a new way to configure the coils in electric motors and generators that takes advantage of advances in semiconductor switches, a truly intelligent electric machine was born. DPM is a control system that integrates wiring of the rotating machine coils into the power electronics, giving the power electronics control of the machine coil wiring configuration in real time. The control system selects the best configuration for a given operating condition using an application-specific algorithm. Exro’s breakthrough approach to generator and motor design and control improves efficiency across highly variable input and output applications. Electric machine coils are usually wired in a single configuration forcing the designer to select a 'best compromise'​ configuration over the range of operating conditions. DPM instead, senses input energy and load, and seamlessly switches coil wiring in any combination from full parallel to full series. In essence, DPM provides voltage control with multiple performance curves corresponding to the coil configurations in the electric machine. Exro’s technology is designed and built into our partner’s electric machine and power electronics for the application. DPM is fully integrated with the power electronics design; there is no separate hardware package.
