Those soft starters are really good. No shocks to the motor or spikes on the line. Perfect for hard to accelerate loads like large fans. Direct drive fans like the one shown are preferred for industrial applications due to the simplicity of construction and no belts to slip or break, but they represent a high torque load on start. Solid state soft starters are perfect for smoothly accelerating the motor without causing voltage disruption on the line.

I visited an industrial plant once, they had a room with 5 500kW fans. After stepping through the door, the sound was like a liquid, nothing got through it, it wasn't neccesarily painful, but the sheer power of these things... If you touched your hat, it vibrated, just from the sound alone. The motors were as big as small vans. Imagine the tons of copper in that machine, and the weight rotating at such speeds.

What my 20 year old ceiling fan sounds like at 3:00am.
