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.
