The Yuyang King (YYK) Bluetooth app is the primary tool for configuring and monitoring high-power BLDC motor controllers used in electric vehicles like e-scooters and e-bikes. If you are experiencing heating ("hot") issues, it is important to note that the controller is designed to auto-shutoff if temperatures exceed to protect the hardware. Essential App Information
App Name: Search for "Yuyangking" or "Emotor" on the App Store or Google Play Store.
Default Password: The standard pairing password is 12345678 (or sometimes 1234).
Initial Connection: Turn on the vehicle's electronic door lock first, then open the app and select the Bluetooth type (BLE or ERD) to scan for your device. Key Features and "Hot" Performance Settings
The "Myself" section contains advanced parameters that directly impact motor performance and heat generation:
Power BOOST: Increases torque by 20%. Use this sparingly as it generates significant heat and will trigger a safety shutoff at
Current Limits: You can adjust both Battery Current Limit and Phase Current Limit (50%–100%). Lowering these percentages can help reduce overheating. Fast vs. Soft Start:
Fast Start: Divided into 10 grades; higher grades provide faster takeoff but put more strain on the motor. yuyang king bluetooth app hot
Soft Start: Higher grades result in a smoother, slower start, which is better for battery longevity and heat management.
Overdrive: Can increase speed to 120%–130% of rated capacity but significantly increases current draw.
ECO Mode: Automatically weakens current to increase mileage and keep the system cooler. Troubleshooting and Calibration
