M
otor soft starts are designed for AC induction motors. Soft starting
is a methos of reduced voltage starting that provides smooth, stepless
accelaration that greatly reduces wear on power transmission components.
Soft Starting reduces motor in rush current by as much as 70%. These
motor controls have Adjustable starting torque, ramp time and flex time.
The flex time adjustment takes up the slack in conveyor systems and
and also adjust the the starting ramp time on lightly loaded motors.
Optionally available Deceleration control adjusts perfect stopping utilising
three potentiometers that control instantaneous deceleration, deceleration
time and the stopping point.
