Applications
Why Motortronics?
Blast Hole Drill — Mining
The MVC4 Weatherproof soft starter doesn't just protect the 7,200V 1,000HP motor driving this blast hole drill. It protects itself from extreme cold, extreme heat, and extreme altitude — so only the operator needs to be in the cab.
Primary Crusher — Mining
The MVC4 runs a 500HP, 2,300V primary crusher with a wound rotor motor. Our customer spends time turning big rocks into little ones instead of pampering an MV VFD.
Coal Conveyor — Energy
The 600HP, 4,160V motors started by Motortronics™ soft starters at this facility convey more than just coal. They deliver reduced belt breakages and eliminate the need for hydraulic clutches.
4,160V Mining Soft Starter — No Vents Needed
The MVC4 includes a starting-rated automatic bypass contactor so it runs cool. That means no filtered fans — not even vents — in this 4,160V 2,000HP MVC4 soft starter. Customers spend less time on maintenance and more time on production.
Cooling Tower Fans — Petrochemical
This methanol plant uses cooling tower fans driven by belt-connected motors. Rain shutdowns cause reverse-direction fan spin, destroying Kevlar belts. VMX-synergy's smart ramp detects motor direction and brings fans to zero speed before performing a controlled restart — dramatically extending belt life.
