The Focbox is the ultimate electric skateboard motor controller.
Some of the key features that make the FOCBOX platform so amazing:
- Supports higher voltage when compared to most hobby grade ESC
- Has current control functions & safety features to help protect your electrical system from damage.
- Supports many different motors via a motor detection function
- Amazing starting torque allowing non-sensored motors to work very well on esk8’s
- It has very good regenerative brake function, an important feature for esk8
- It has a very advanced open source programming tool catering to many different use cases
- It is compact
So why do we need a new & improved VESC?
There are a few issues with the current version 4 VESC, these issues are mostly related to usability, reliability & manufacturability.
DRV ERRORS: The DRV chip is a sensitive component that can report errors for many different reasons. Some people have discovered ways to prevent this from happening and many experienced VESC vendors claim it is related to the other components that share the space around the DRV. There is some evidence that upgrading a few key components has shown to improve the reliability.
SHORTING THE VESC: The VESC doesn’t have a proper case to protect it & it has a separate Capacitor PCB with exposed pins & wires that can easily get placed in the wrong spot causing a short.
OVERHEATING: The existing form factor doesn’t allow the end user to easily install heat sinks (or a proper case) to improve the thermal properties and allow passive cooling to occur. This is not an issue for most people, however it is a weak link that can be a problem for users who like to push the limits of the existing architecture.
SOFTWARE: The BLDC tool is not the most user-friendly interface your will ever encounter, Personally I think it is fine & most people can learn it after watching a few videos online. But there is definitely room for improvement.
MASS PRODUCTION: The existing VESC & BOM were never designed to be made at scale in a large PCB production facility, it was designed to be ‘easy’ to hand solder by the hobbyist at home. This is a huge issue when doing large scale production as it increases the chance for manufacturing faults & increases the cost of production. Furthermore, The process of final assembly of the main PCB with a separate capacitor PCB as seen on the existing VESC made it difficult to perform testing in a timely & systematic manner.
