Project Innovation + Advantages:
Imagen Energy will develop a silicon carbide (SiC)-based compact motor drive system to efficiently control high-power (greater than 500 kW) permanent magnet electric motors operating at extremely high speed (greater than 20,000 rpm). Imagen’s design will address a major roadblock in operating electric motors at high speed, namely overcoming large back electromotive forces (BEMF). Their solution hopes to maximize the capabilities of the SiC technology and associated digital control platform, thereby bringing the overall drive system performance parameters to levels unachievable by current Si-based power conversion systems. If successful, the project team will demonstrate a motor drive capable of handling large BEMF and increase motor system efficiency over a broad range of operating speeds, a useful combination for high-speed applications in the oil and gas industry, high-speed/high-power compressors, grid-connected energy storage, and renewable energy generation.
