While I was browsing Alibaba today I’ve found this:
Seems like WINBOARD is making their own ESC now. Looks pretty good.
This is what they claim on their Alibaba page:
What WINboard FOC skateboard features?
- Generate full torque at zero speed, low energy with high performance, increase efficiency by 5%-8% than any other skateboards
- Longer riding distance at single charge and extended battery life
- Electric current is relatively low, less than 9A
- Quiet motor without any noise makes your skateboard with higher efficiency
- Easy to install and fits any skateboards, say goodbye to bulky wires if make your own skateboard.
- We have more than 10 years in this field is the guarantee for your satisfaction.
What is the difference between VESC and FOC? FOC genertate highest torque at the beginning speed with very low rmp, electric current is ver low, less than 9A, extending battery life and longer riding distance. What is more, quiet motor without any noise and heating problem. In this way, skateboard efficiency dramaticlly increased by 5%-8% than any other motor controller. However, VESC gets highest torque in a relatively higher speed, electric current much larger than FOC, which would do harm to skateboard battery and lower the performance and efficiency.
