SUR RON POWER SYSTEMS for DIY and electric motorcycle companies

Like most companies in Electric Vehicle world, Sur-Ron decided to expand their product line to electric motorcycle Power systems ( components ) used in Light Bee and other prototypes for buying as an individual product. Sur-Ron now offers a variety of power systems: Electric motors, FOC Electric controllers, and full power systems ( motor + controller )

SUR-RON Power Systems

The Power Department of ChongQing Quilong Technology Co., Ltd is committed to the research and development as well as manufacturing of the core technologies of electric motorcycle power systems and provide technology services for power systems and solutions to the integrated motorcycle power systems, whose products include motors, reducers, and motor controllers etc..

Sur Ron Power Systems use in-house FOC controllers

( Field Oriented Control – FOC applies to three-phase Brushless Motors that are operating in sinusoidal mode.Field Oriented Control produces great results. Without it, current on the motor will grow to potentially very high or even damaging level. Most of that current goes wasted in heat in the motor coils, motor wires, and controller transistors. Turning FOC on causes an immediate and automatic correction of the PWM phases and practically eliminates the energy loss due to the Flux current. )

The system comes with large-power PMSM motors, with an adaptation of advanced vector control algorithms and a combination with control strategies based on the motorcycle ride experience, and will provide smart, smooth control and powerful, highly efficient power output, which is mainly used in mid-range and high-end electric motorcycles.
