Design Principle and Innovations​

PUMBAA EV’s developed flat-wire motor replaces traditional round wires with flat rectangular copper wire windings. Combined with optimized slot shapes, increased fill factor, and refined magnetic circuit design, it significantly improves the copper ratio per unit volume and heat dissipation performance. Paired with an improved rotor structure and high-precision manufacturing processes, the overall motor achieves breakthroughs in power density, efficiency, and reliability.

Key Advantages​

• Significant Increase in Power Density: Higher output per unit volume allows for optimization of overall machine size and weight, benefiting vehicle lightweighting.
• Improved Heat Dissipation and Lower Temperature Rise: Synergy between flat wires and optimized cooling channels controls temperature rise under continuous high-load conditions, reducing demagnetization and thermal damage risks.
• Excellent Low-Speed Torque Control: Less torque ripple and faster response, suitable for aerial platforms and precise handling needs.
• Mass-Production Ready Process: The company has achieved automated production of flat-wire windings, ensuring batch consistency and cost control.

Supporting Control Strategy​

The flat-wire motor is deeply coupled with PUMBAAEV’s self-developed e-Drive controller, which monitors temperature, load, and electrical characteristics in real-time. It uses vector control and MPC algorithms to dynamically optimize current distribution and efficiency maps. It supports cloud data backhaul, OTA updates, and AI-based continuous performance optimization.

Application Scenarios and On-Site Performance​

In auto show demos and multi-scenario field tests, the flat-wire motor demonstrated efficient, smooth, and reliable performance in excavators, loaders, aerial platforms, warehousing/handling, and agricultural machinery. Test data shows system efficiency improvements of 15–25% in typical heavy-duty start-stop and continuous operation scenarios, with a significant extension in continuous operation time.
