1 . FOC-180sinusoidal drive controller applied to BLDCM or . It takes only 3 minutes for the motor to be well matched on its best electronic angle at the first time. 2 . the motor torque ripple will be reduced to the minimum, so as to electric vehicle to run without any noise and vibration, smoothly, and comfortably. 3 . the precise current ring can provide accurate torque input to meet the requirement 0f torque output during vehicle starting and climbing. 4 . 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 5 . Built-in various protection: locked- 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. 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. The peripheral interfaces: reverse, , anti-theft, electronic brake, etc. Parameter modifications and settings are available through online configuration with online computer. General Spec .: 1 . power supply: 48V, 60V ,72V battery , MAX DC current:60A , Max phase current:170A 2 . Product Size: 215x142x62mm 3 . Net Weight:2.2 kgs 4 . Testing way: Hall sensor 5 . Phone App or computer software can communicate with the controller to parameters MQCON(Sabvoton) SVMC programable sine-wave motor cotroller works with high efficiency, less nosie, and lower energy comsuption, which makes your electric vehicles or electric motorcycles more comfortable and sier to control.
