Ruggedized Variable Frequency Drives
Invention House manufactures American-made variable frequency drives that meet the needs of multiple industries.
American-Made Variable Frequency Drives for HVAC, Aviation, and Military Applications
Finding the right variable frequency drive to power essential processes can be difficult. Many companies experience the frustrations of dealing with off-the-shelf equipment before realizing they need a customized drive that suits their needs. Standard equipment can struggle to maintain a constant speed during demanding jobs, leading to burnout and impacting a motor’s efficiency. That’s why Invention House offers ruggedized variable frequency drives built to withstand environments over a wide range of voltage, frequency, and temperature. An example is our single-phase drive for a linear vibration motor used in the MVE Fusion(r) freezer shown here. Our motor drives feature integrated functionality that enhances reliability and reduces system complexity.
Signs You Should Consider a Customized Variable Frequency Drive
Many off-the-shelf products are designed for basic commercial and industrial needs. However, many companies need motor drives capable of operating in extreme elements. If your drive fails to work in cold weather regions, high-altitude areas, or you need it to travel frequently, consider purchasing a ruggedized variable frequency drive. Invention House’s equipment is designed to meet strict operating specifications, including:
- Input/output frequencies up to 400Hz
- Temperature range from -40℃ to 55℃
- Continuous Vibration up to 2grms
- Shock (drop, near detonation) up to 40g
- Humidity up to 95% non-condensing
- Stall prevention
- Auto restart
- Operation at Altitude up to 14,000 ft.
Our Variable Frequency Drives
We understand the difficulties of finding the right equipment to power your processes; that’s why we offer three variable frequency drives that suit multiple industries.
Link to: 3-Phase Motor Drives
3 Phase Motor Drives
Variable frequency drives for military applications must work in extreme temperatures and high altitudes. Invention House’s 3 phase motor drives meet military-grade compliance and maintain speed in regions that feature sand and smoke.
Link to: 400 Hz VFD Motor Drive
400 Hz Motor Drive
Controlling the engine that powers helicopters and other aircraft in the aerospace industry requires a durable variable frequency drive that takes up little room. Invention House’s 400 Hz motor drive is lightweight and combines multiple processes.
Link to: Single-Phase VFD
Single Phase Motor Drives
Invention House offers two types of single-phase motor drives that enable manufacturers to control the speeds of critical equipment. Our drives are built with multi-control features that allow company owners to maximize facility space.

Customized VFD With Specifications That Meet Military-Grade Compliance
Variable frequency drives for military applications must meet strict compliance standards for performance and durability. Invention House takes pride in being a fast-response team that designs power management systems and VFDs used in cooling fans, weapons turrets, radar systems, and tent pumps. Our drives feature the electronic design, power circuit design, assembly, PCB layout, embedded software, and failure analysis to meet military-grade compliance for the following:
- MIL-STD-810 for environmental engineering considerations and laboratory tests
- MIL-STD-461 for electromagnetic interference characteristics requirements for equipment
- MIL-STD-464 for interface electromagnetic environmental effects requirements for systems
The experts at Invention House regularly test and troubleshoot our variable frequency drives to verify they can withstand shock, extreme temperatures, and altitude variations.
