1. It only takes 3 minutes for the motor to match to the best electronic angle for the first time. Minimize the torque ripple of the motor to that the electric vehicle runs smoothly and comfortably without noise or vibration. FOC-180sinusoidal drive controller applied to BLDCM or .. 2. The precise current loop can provide precise torque input to meet the needs of 0f high torque output when the vehicle starts and climbs. The controller adopts the space vector converter control algorithm with high efficiency, which can effectively reduce the temperature rise of the controller and extend the cruising range 3. Built-in multiple protections: stall protection, over-current protection, overload protection, over-temperature protection, speed protection, over-voltage protection, under-voltage protection, etc., to effectively the safety of the electronic control system and vehicles. 4. The system status and fault intelligent management system can effectively monitor the external input status of the current system operation mode and system fault conditions, and the flash at the same time, which is convenient for diagnosis and maintenance. 5. Abundant peripheral interfaces: reversing, cruise, anti-theft, electronic brake, etc. Parameter modification and setting can be performed through online computer online configuration Colour:black Material:Metal Package Contents: 1 x 45A Controller 1 x USB Cable Only the above package content, other products are not included.
