Invention House is a reliable source for 20hp, 230-volt, 400hz motor control drives for OEM application. Invention House has been designing and building custom motor drives for over 20 years. We have built 400 hz aircraft variable frequency drives for commercial and military applications, including demanding environments such as desert conditions and aviation.
Our specialty is custom motor drives, where we integrate the drive, power supply, and PLC on one or two boards.
Application for our custom, reliable 3-phase 230-volt, 400hz (input / output) motor drives include:
Invention House 3-phase, 230volt drives are designed to meet demanding specs, including ambient temperatures from -45c to +55c, and withstand 40g shock and 2g rms vibration. This drive supports 400hz input or output. Drive control is set up through standard terminals or Modbus. Our 3-phase, 230-volt drives require minimal cooling – just 5 cfm across the heat sink fins.
