Specialty Motor Applications

• Synchronous Exciter
  The MVC Plus Series can be integrated with synchronous exciters in both brush and brushless packages.
• Wound Rotor
  Apply the exact rotor resistance needed for your application, while soft starting the stator with the MVC Plus Series.
• Reversing or 2 speed
  Controls can be built-in, or the MVC Plus Series can be retrofitted behind existing 2 speed controllers.
• Inching / Spotting Control
  For low speed load positioning to line up access ports, test blade positions, etc.
• Multiple Motor
  Control and protect multiple motors from one soft starter
