Urban driving conditions typically require low torque and power, causing electric motors to operate outside their optimal efficiency range. The Dynamic Motor Drive (DMD) concept addresses this challenge through a patented approach called intelligent freewheeling, which intermittently cuts motor current during low-load operation. This allows the motor and inverter to function, on average, at higher efficiency levels without compromising smoothness or drivability. By dynamically managing torque delivery instead of maintaining constant low torque, DMD significantly improves energy efficiency in city driving scenarios. This innovative control strategy demonstrates how optimizing transient operation can enhance overall system performance, reduce energy consumption, and support the development of more efficient and sustainable electric mobility solutions.
