Further Description
Encoder Connector
The VTB beast motor is designed with circular connectors through IMD (In-mold Decoration) technique for better usage with other VTB products. It provides a high waterproof level at IP67 rating. We also keep the square-shape connectors if you prefer to get a motor separately. It is more versatile and works with your controller. However, it bears higher risks for water leaking in. The PVC wire is not with full coverage so it can create a pathway for water to enter the motor.
Sensing Method
There are typically two types of sensors: Hall sensors and encoders. Hall sensors have strong compatibility which is used very commonly, but it underperforms in speed feedback and throttle sensitivity. Especially when a vehicle is passing through obstacles with more pushes or when tires lose traction and try to reduce speed and torque, Hall sensors have slower response compared to encoders. Encoder is the premium option for riders who do wheelies and care about control and level of precision. We have decided on encoder for VTB motors.
