Electronics for the PMSM (BLDC) Motor Driver

How do we build the best variable frequency drive (VFD) for our motor?

In the age of arduino and many other easily accessible microcontroller platforms we think it is a shame how most VFDs are difficult to program and to update.

We will not use a ATMEGA like arduino but rather an ARM processor as those now became cheaper and more powerful than ATMEGA microcontrollers.

Plus we believe that a servo drive should not be more expensive than a VFD that just changes the speed of a motor.

Through open source we want to change these issues.
