DeepDrive双转子径向磁通电机技术报告-2025-07-技术资料_39页_5mb

Dual-Rotor, Radial-Flux electric machines are presented as a solution for low-cost, highly efficient drive units, achieved through innovations in design and winding technology. Key benefits include reduced torque ripple (<0.5%) and optimized performance characteristics, leading to higher efficiency and lower costs compared to traditional setups. These machines operate at a nominal DC-voltage of 650 Vdc, delivering peak torque of 430 Nm and continuous torque of 210 Nm, with power outputs reaching 300 kW peak. They feature a compact design (outer diameter: 255 mm, active weight: 22 kg), making them suitable for automotive propulsion systems and other applications. DeepDrive, a UK-based company, focuses on rapid evolutionary development, supported by seed and series funding totaling €4.3m–€15m, enabling further advancements and market expansion.
