Product information

For more products, please visit our shop Important note Brushless controller is for brushless motor only. Not suitable for brush motors, please don't buy the wrong one. Please be sure to test the motor parameters by plugging in the learning wires the first time after the controller is installed! If using PAS pedal assist. Please use dual Hall PAS sensors The motor needs to with Hall sensor, if you use it for Hall-less brushless motor, it will always display the E07 fault code. If your motor is a hall-less motor or the hall is damaged, please choose carefully whether you accept to display the E07 code all the time. If you can't accept it, please don't order it because the parcel is sent from China and the international shipping cost is very expensive. FOC Sine Wave Controller & SW900 LCD Display Kit E-bike/Scooter Repair & Conversion Universal Kit High-power motor high-speed controller Controller Introduction This controller is a 3-mode sine wave controller for brushless gearless motors and geared Hall motors. The sine wave drive has low noise, strong power and stable drive, this controller supports up to 40A current. The controller with self-learning wires can match almost all brushless motors. tips If you use it for Hall-less motors, please choose our S810 LED panel kit, for Hall-less motors the LCD will always show E07 error code. WinXu Tech protocol controller wiring diagram Tips This is a true sine wave controller. It does not support cruise and 6 km/h mode. Please pay attention to cruise requirements. If you need cruise, please do not order. The cruise button operation on the LCD is invalid, please note. Tips This is a true sine wave controller. It does not support cruise and 6 km/h mode. Please pay attention to cruise requirements. If you need cruise, please do not order. The cruise button operation on the LCD is invalid, please note. LCD Setting Parameters & Error Code Explanation Decimal Fault Codes E00: Normal status E01. E02: Brake E03: PAS sensor fault E04: 6KM/H cruise mode E05: Real-time cruise E06: Battery undervoltage E07: Motor failure E08: throttle fault E09: Controller failure E10: Communication signal reception failure E11: Communication signal transmission fault E12: BMS communication fault E13: Headlight fault How to enter Setup Mode Long press the + and - buttons for 3-5 seconds after switching on the computer to enter the setting mode, the parameters will blink. Short press M button to switch parameters, press + and - buttons to select parameters. Parameter introduction P00: Restore factory setting (Controller not supported） P01: Backlight Brightness P02: Mileage unit P03: Voltage selection P04: Sleep Time P05: PAS Gear P06: Wheel Diameter P07: Speed Magnet P08: Speed Limit （Controller not supported） P09: Zero Start Non-Zero Start P10: Drive mode setting, 0: PAS drive, 1: throttle drive, 2: PAS and throttle drive P11: PAS sensitivity setting P12: PAS start strength setting P13: PAS magnet disc type setting P14: Current Limit Setting （Controller not supported） P15-16-17-18-19: Functions not yet opened, please ignore do not set up Tips This controller is 40A max current high speed controller, 1500W motor our lab test E-bike speed 57km/h (40A 60V battery). This controller does not support P08 speed limit and P14 current limit set from LCD. And the external speed limit connector of this controller only limits the speed to 6km/h, it doesn't support 25km/h speed limit. If you need 25km/h speed limit, please order your brand original controller, this controller can't meet your requirement, thanks. This controller is suitable for users with modification requirements and users with high speed requirements, not suitable for users with 25km/h speed limit requirements. We must tell the truth so you can avoid ordering by mistake. WINXU FOC Brushless Controller Detailed Display High-quality Lead-free PCB process, fire-resistant wire material Controller Introduction This controller is FCO sine wave design for brushless motor with hall sensor. Brushless Hall motors are 3+5 wire or 3+6 wire, these two types of motors are best suited for Forever FOC controllers. This controller is suitable for electric scooters as well as electric bikes, it is very compatible and designed for modification users and repair shops. This controller has self-learning design, when you install it for the first time, there may be motor jitter, this is normal because the controller doesn't detect your motor parameter, you can short the self-learning wire for 5 seconds, the controller will automatically check your motor parameter and auto-compatible. The advantage of this design is that the controller is compatible with almost all brushless motors. Many single mode sine wave controllers on the market do not have self-learning wires, and this controller is designed with self-learning motors to perfectly solve this problem that bothers users. Please don't need to worry if your motor drives in reverse direction after initial installation, this is normal, you can short connect the self-learning wire to change the initial direction of the motor. If you want accurate LCD speed display, you can enter LCD setting mode and set your motor wheel diameter in P06 in inch. Set the speed magnet in P07, normally you can set it to 23,. After setting P06 and P07, you can test the real time speed with map navigation APP, if the LCD display speed is bigger than the navigation display speed, then you can reduce the parameter of P07 to lower the speed display ratio. If the LCD display speed is less than the navigation display speed, you can increase the parameter in P07 to increase the speed display ratio. After finding the exact speed that suits you in this way, you will see the LCD displaying the exact speed.
