American-made 3-phase VFDs that comply with strict military compliance standards.
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:
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.
As a small and independent company, Invention House can customize our variable frequency drive for 3-phase motors to meet your needs. Contact us today to learn more about the advantages of our products.
