Motor
soft starts are designed for AC induction motors.
Soft starting is a method of reduced voltage starting
that provides smooth, stepless acceleration that greatly
reduces wear on power transmission components. Soft
starting reduces motor in rush current by as much
as 70%.
These Solid State 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 utilizing three potentiometers that
control instantaneous deceleration, deceleration time
and the stopping point.
