Ruggedized Single-Phase VFD
Invention House builds ruggedized flange-format 120-volt single-phase VFDs for controlling motors in OEM equipment.
Customized 120 Volt Single-Phase VFDs for OEM Equipment
Many manufacturers sell off-the-shelf variable frequency drives (VFDs) that feature standard specifics to power OEM and commercial equipment. But industrial processes across industries aren’t static. They are done in a wide variety of temperatures, environments, and shock conditions. Using basic VFDs in extreme elements can create system failure that impacts productivity and efficiency. The Invention House team understands the critical role VFDs play in daily operations and offers customized single-phase VFDs designed to meet the needs of any industry. We produce two flange chasis drives capable of operating in rugged environments over a wide range of voltage, frequency, and temperature. Invention House is a US-military approved vendor: Cage #58XJ1
SPD-2230 Single-Phase OEM Motor Drive
The SPD-2230 single-phase motor drive is built on an aluminum flange chassis and conformal coated. Current applications include cryogenic compressors and traditional and linear motors. The SBD-2230 can operate in extreme temperatures ranging from -40℃ to 55℃. With functional programming, a serial interface, and connector-based input/output for quick factory assembly, this single-phase motor drive is perfect for demanding applications. Other specifications include:
- Single-phase In/Out

Enhanced Speed Control For Single-Phase Motor Drives With Multiple Applicaiton
Many manufacturers experience the frustrations of working with standard drives before they realize they need specific features for their processes. As a small and independent company, Invention House is ideally suited to produce custom and ruggedized single-phase VFDs capable of powering engines for the following applications (Cage #58XJ1):
- Military-grade power conversion
- Vibratory feeders, shears, and compressors
- Transformer drive, including resonant transformers
- Boiler combustion fan drive
Our single-phase VFDs have built-in intelligence that take inputs from the command and sensors to adequately control motors, relays, solenoids, and speed. These multi-control features increase working space in a facility by minimizing the equipment needed to control processes.
From Single-Phase to Three-Phase VFD, Invention House Has You Covered
The Invention House team has over two decades of experience developing and manufacturing custom, ruggedized motor drives that suit the needs of multiple industries.
Along with our single-phase VFDs we also offer American-made 3-phase VFDs that meet military specifications and 400 Hz drives ideal for aerospace companies. We also offer testing services that verify our equipment withstands your environment’s stress, shock, vibration, and lighting levels.
