Variable Speed Drives - Advanced Naval Drive Technology

Our military-grade Variable Speed Drive, based on AC-link Technology, has been certified to all standards for operation on board naval military vessels.

Benefits over Pulse Width Modulation (PWM) Drives

  • Low input & output emissions
  • Very low input harmonics - Less than 3% of full load fundamental
  • Low output voltage transients (dV/dt) - As much as 1000 times lower than PWM
  • Increased installation flexibility - 500' or more between motor & drive
  • Use with standard induction motors (non-inverter grade motors)
  • Increased motor bearing life
  • Lower stored energy
