American-Made 3-Phase VFD

American-made 3-phase VFDs that comply with strict military compliance standards.

Variable Frequency Drives for 3-Phase Motors That Meet Military Specifications

It can be a challenge to find the ideal variable frequency drive (VFD) to power military equipment. Off-the-shelf options lack the high-performance capabilities to maintain power in rugged environments and the durability to withstand difficult travel conditions. A quality 3-phase VFD should provide the necessary motor speed control while withstanding harsh elements, including temperature extremes, shock, and particulates.

Invention House is a military-approved small-business contractor (Cage #58XJ1) with over two decades of experience designing and building VFD motors that meet strict, military-grade specifications. Our drives have been used in cooling fans, blower motors, radar systems, and HVAC equipment and meet engineering capabilities for:

  • Electronic design
  • Power circuit design
  • Electronic assembly
  • PCB layout
  • Embedded software
  • Human interface
  • Failure analysis
  • MIL-STD-810 compliance for environmental engineering considerations and laboratory tests
  • MIL-STD-461 compliance for electromagnetic interference characteristics requirements for equipment
  • MIL-STD-464 compliance for interface electromagnetic environmental effects requirements for systems

We understand that testing standard power drive solutions can be a frustrating experience, so we provide equipment that offers the following advantages:

Customization

Sourcing motor drives from major manufacturers can be stressful because their production standards often limit customizable options. Invention House is a small and independent business, enabling us to design 3-phase VFDs to suit your requirements.
