100% brand new The integrated design of the ESC and the motor greatly reduces the overall volume and weight, and makes the layout and wiring of car frame simpler and more convenient. The FOC driving mode provides excellent low speed torque and smooth running at extreme low speed, which makes this superior to the common sensored brushless power systems. Thanks to the sine wave driving mode, the whole system has high efficiency, low heat, and effectively extends the runtime. Additionally the motor runs more quietly and smoother. IP67 waterproofing gives this system excellent waterproof and dustproof performance. Under various weather conditions, the whole system can easily deal with environments containing silt, ice, snow, and water. Intelligent torque output and speed closed-loop control, experience the cruise control and steep slope slow descent function. Active drag brake force adjustment, providing super strong parking capacity on slope. Multiple protection functions: battery low voltage protection, overheat protection, throttle lost protection, lock-up protection. It supports LED program box to set ESC parameters, and has independent parameter setting interface, which is integrated on electronic switch, making setting parameters more convenient.
