Here are the basics for using brushless DC motors in a VESC OneWheel application:
- Motor Connection:
- Splitting into 6 Pins (Stock XR Molex Connector):
- Divides the 3-phase motor wires into 6 pins.
- Compatible with the Stock XR Molex Connector for a standardized connection.
- Leaving 3 Phase Wires with Gland:
- Maintains the 3-phase motor wires.
- Uses a gland for secure and protected connections.
- Offers flexibility without proprietary connectors.
- Proprietary Connectors (e.g. FloatWheel, Fungineers):
- Utilizes specific connectors designed by companies like FloatWheel and Fungineers.
- Provides a unique connection solution tailored to their systems.
- May offer enhanced performance or features with proprietary designs. (like waterproofing or all in one solutions)
- Power Supply:
- Choosing a well-suited battery is crucial if you somehow get your hands on a non-standard motor. (For example the lower kv of the V1 CannonCore would be better suited with a higher voltage battery pack)
- Programming and Configuration:
- Use a computer or android phone with VESC Tool software to program and configure the VESC (while VESC tool works on iOS it is not recommended for initial setup). This includes setting parameters such as battery voltage, motor type, maximum current limits, and other parameters specific to the OneWheel application. Calibration of a remote control may also be necessary. (like remote tilt)
- Testing and Tuning:
- Conduct initial tests in a controlled environment to ensure proper motor rotation, braking, and responsiveness. Fine-tune the VESC parameters as needed for optimal performance and efficiency.
- Kv (Velocity Constant):
- Indicates the motor's speed characteristic, representing the RPM per volt under no load.
- Higher Kv values imply higher speeds, while lower Kv values signify greater torque at lower speeds.
- An important factor in selecting a motor that aligns with the desired application's speed and torque requirements.
- Stator Size:
- Refers to the dimensions of the stationary part of the motor around which the coils wind.
- Larger stator sizes generally contribute to higher torque and power capabilities.
- Larger stators tend to stay cooler due to increased surface area, facilitating better heat dissipation.
- Hub Size:
- 6 Inches:
- Considered optimal for aftermarket choices, aligning with the standard go-kart size and having a longer presence in the market.
- Offers a wide range of aftermarket options, providing flexibility for customization.
- 6.5 Inches:
- Considered less favorable due to increased vulnerability to damage.
- Has a smaller sidewall, potentially making the hub more susceptible to impacts.
- Limited aftermarket options compared to the 6-inch standard.
- Less sidewall can lead to a worse ride quality, as it provides less cushioning against bumps and shocks.
- 5 Inches:
- Emerging as a promising option.
- Offers better ride quality.
- Less likely to be damaged due to a design that prioritizes the most sidewall possible.
- Frequency of Use:
- High community usage enhances the availability of data, mods, and troubleshooting resources for the motor.
- More widespread adoption leads to a larger user base, fostering a collaborative environment with shared experiences and insights.
- Popular motors often have established communities, forums, and online resources, providing valuable information for modifications and addressing common issues.
- Consideration of community frequency can simplify the troubleshooting process and improve overall user support for the motor.
