• The base (max.) frequency can be calculated from
the rated number of revolutions of the motor (min
and the number of poles in the following formula.
Base (max.) frequency (Hz) = rated number of
-1
revolutions (min ) × number of poles (pole)/120
• The motor constant Ke is the peak value of the
phase inducted voltage (mV) per electrical angular
speed (rad/s).
