1. FOC-180sinusoidal drive controller, suitable for BLDCM or . UART 1.3DW protocol. It only takes 3 minutes, and the motor can match the best electronic angle in the first time. 2. Minimize the torque ripple of the motor to that the electric vehicle runs without noise, vibration, smoothness and comfort. 3. The precise current loop can provide precise torque input to meet the requirements of 0f high torque output when the vehicle starts and climbs. 4. Using the space vector converter control algorithm, the controller has high efficiency, which can effectively reduce the temperature rise of the controller and extend the battery life 5. Built-in multiple protections: stall protection, over-current protection, overload protection, over-temperature protection, over-speed protection, over-voltage protection, under-voltage protection, etc., to effectively the safety of the electronic control system and vehicles.
