Typical Across-the-Line Response
The figure above shows how starting
torque surge during motor starting can
cause damage to the motor and to
driver equipment.
STC Response
The figure above shows how the STC
controller is effective in decreasing
the magnitude of starting torque
surges.
Comparison of Across-the-Line
Response versus STC Response
The figure above shows the comparison
of the STC controller versus a typical
across-the-line start.
