Tips: Choose a soft starter for fixed speed running motor
A variable frequency drive (VFD) is much more expensive than a soft starter, and has much higher energy losses so is more expensive to run. For a fixed speed operating induction motor, a soft starter is a lower capital cost and a lower running cost than a VFD. A VFD may not be necessary unless speed or torque control is required. Of course if money is not concerned a VFD is much better a soft starter and a VFD normally has built in all of soft start features.
