Tips: Can a soft starter control the induction motor in variable speed?
A soft starter can NOT control induction motor speed, it only restricts motor starting current by applying the voltage in a ramp to avoid inrush current impact on the motor. To vary the speed, you should go for a variable frequency drive which can control the induction motor speed along with starting torque, but cost much more than a soft starter. The selection between VFD and soft starter depends on lots of factors, you can check our blog post regarding VFD vs Soft Starter for details.
Existing reviews
This 75 hp soft starter is not only reasonably priced, but also performs excellently. I use it to control large pump equipment and the starting process is very smooth with no current shocks.
