Since  its  release  in  2013,  InstaSPIN-FOC  has  enabled  countless  engineers  to  design  high  performance  sensorless  field  oriented  systems  in  a  fraction  of  the  time  it  used  to  take.   Using  the  low  cost  InstaSPIN-FOC  enabled  LaunchPad  and  Motor  Drive  BoosterPack  students  will  learn  about  MotorWare,  how  to  properly  set-up  user  files,  tips  &  tricks  for  Motor  Identification,  run  in  Torque  Mode,  Speed  Mode,  Tune  Speed  Controllers,  Over-Modulation,  and  Field  Weakening.

1. What is FOC?
Field Oriented Control (FOC) is a technique to
precisely
orient
the
stator
magnetic
field
w.r.t. the
rotor
magnetic field in an attempt to
control
maximum torque per minimum amp (current)
This orientation is
exactly what a
BRUSHED motor
accomplishes
thanks to brush
commutators
-Id
FOC is quite straightforward if you know the position of the
rotor…
