• This chart illustrates the parabolic relationship
between output power and rotation speed at
different pressure levels. Notice that there is
no power available at zero and at maximum
rotation speeds.
• This chart illustrates that any external load will
cause a reduction in speed; the more power
demanded, the greater the speed reduction.
To the right of the peak lies the working area
of the spindle, the peak being its limit. The
spindle will stop rotating should the power
exceed “Max Power”.
