Integrated ePowertrain Solution for Electric Dump Trucks: Motor + 2-Speed AMT
Integrated ePowertrain Solution for Electric Dump Trucks:Motor + 2-Speed AMT This integrated ePowertrain solution is ideal for Class 7 electric heavy-duty trucks around 12 tons, such as electric dump trucks. It combines a high-performance motor with a 2-speed AMT to optimize system efficiency and extend the lifespan of key components, even under heavy-duty operating conditions. Lower energy consumption Higher torque performance Long-term durability Safety and environmental friendliness Enhanced driving comfort Email: contact@brogenevsolution.com Get Custom Quote Optimized ePowertrain for Heavy-Duty, Low-Speed Operations Background In today’s electric heavy-duty truck market, many OEMs adopt a direct-drive architecture – using a single PMSM to drive the shaft – mainly to reduce cost. While simple and cost-effective, this design struggles to deliver efficient motor performance across both low-speed high-torque and high-speed low-torque working conditions. This challenge becomes even more critical for electric dump trucks operating in urban construction and transport scenarios, where vehicles often run under heavy-load and low-speed conditions such as uphill driving or stop-and-go operation. Our Solution: PMSM + 2-Speed AMT ePowertrain To overcome the limitations of traditional direct-drive systems in electric dump trucks, we provide a dedicated ePowertrain solution that pairs a high-performance PMSM with a 2-speed AMT. This configuration is specifically engineered to enhance energy efficiency and extend system durability under heavy-duty, low-speed operating conditions. This combination enables the motor to operate more efficiently in low-speed, high-torque scenarios – such as hill climbing or fully loaded starts, where energy losses are typically high. By optimizing motor load and shifting gears as needed, this system helps reduce overall power consumption and prolong motor life, even during continuous high-load operation. In addition, the inclusion of a 2-speed AMT provides greater flexibility for PTO integration, which is essential for construction and utility vehicles that require hydraulic lifting or other auxiliary power applications.
