The quicrun fusion mini16 foc systemfeatures an integrated design of the esc and motor, simplifying the car frame layout and wiring for enhanced convenience. Employing foc (field oriented control)driving mode for rock crawlers, it delivers strong low-speed torque, improving upon standard brushless systems and often being preferred over brushed systems for its overall feel. The system boasts high efficiency, generates less heat, and effectively extends run time while the motor operates more quietly and smoothly. With an ip65 protection grade, its capable of running in all conditions. It offers intelligent torque output and speed closed-loop control for precise handling and includes active drag brake force adjustment, providing superior holding power on inclines. Equipped with a strong built-in switch mode bec, the system offers a continuous current of up to 4a and supports switching between 6v and 7. 4v, enabling it to drive high-torque and high-voltage servos. It also includes multiple protection functions: battery low voltage, overheat, throttle loss, and lock-up protection. For convenient esc parameter settings, it supports led and lcd g2/pro program boxes. (hw30120403)
