    8. Mobile phone App or computer software can communicate with the controller to modify parameter
    RisunMotor programmable sine-wave motor controller works with high efficiency, less noise, and lower energy consumption, which makes your electric vehicles or electric motorcycles more comfortable and easier to control. Our designed friendly interface of the programmable motor controller makes you set the parameters, conduct the tests and obtain the diagnostic info easily and quickly.
    1. FOC-180° sinusoidal drive controller applied to BLDCM or PMSM.
    2. It takes only 2-3 minutes for the motor to be well matched on its best electronic angle at the first time.
    3. The motor torque ripple will be reduced to the minimum, so as to ensure electric vehicle to run without any noise and vibration, smoothly, and comfortably.
    4. The precise current ring can provide accurate torque input to meet the requirement of large torque output during vehicle starting and climbing.
    5. The controller enjoys high efficiency due to space vector converter control algorithm which can effectively reduce the temperature rise of controller and extend battery life mileage
    6. Built-in various protection: locked-rotor protection, over-current protection, overload protection, over-temperature protection, speed protection, over-voltage protection, under-voltage protection and so on, effectively ensuring the safety of electronic control system and vehicle.
    7. System status and fault intelligent management system can effectively monitor the current system operating mode external input state, the case of system failure, and the LED flashes at the same time to facilitate the diagnosis and maintenance.
    8. Multi peripheral interfaces: cruise, anti-theft electronic brake, etc.
    9. Parameter modifications and settings are available through Mobile phone via Bluetooth or computer via USB data cable
    10. CAN BUS is optional to communicate with body instrument and BMS
