Equipped with advanced power electronics, the Coil Driver™ can drive any AC motor with increased performance in a wide range of applications up to your peak power.
Coil Driver™ was named a Gold award winner for the 2022 Edison Best New Product Awards™ in manufacturing, logistics and transportation.
Intelligent: Switch between Series and Parallel modes in real-time
Powerful: Enhanced performance at high speed, better startability and gradeability at low speed
Efficient: Improved operational efficiency, less mechanical loss, extended range
Exro has developed a new dynamic controller, the smart Coil Driver™, that replaces the standard controller of an electric motor. This controller effectively creates an intelligent electronic gearbox inside the motor. Our Coil Driver™ electronically switches the motor coil configuration in real time, seamlessly and under demand. The intelligent coil switching establishes a greater depth of control of an electric motor using the coils already installed. The ability to change configurations allows efficiency optimization for each operating mode, resulting in smarter energy consumption. The Coil Driver™ automatically selects the appropriate configuration in real time so that torque demand and efficiency are optimized.
Independent third-party organization AVL conducted multiple tests on Exro’s Coil Driver™, demonstrating its coil switching capabilities to optimize performance of an electric motor through the power electronics. Results also prove Exro’s Coil Driver™ has successfully combined two traditionally separate formats of power electronics for the first time, that has the potential to reduce the weight and cost of electric powertrains.
Exro Technologies’ A020 inverter is an advanced motor controller, created with revolutionary Coil Driver™ technology. Exro’s patented technology optimizes the powertrain, enhances torque, and improves performance in 2&3-wheelers, ATVs, light utility vehicles, and light duty applications.
