Invention House is pleased to share the news that we provided custom 400 Hz electric motor drives for the protective container for the James Webb Telescope. The telescope was transported all over the world inside an enormous climate-controlled container, called STARRS (Space Telescope Transporter for Air, Road, and Sea).

The custom 400 Hz motor drive system supplied by Invention House allowed the container’s air conditioning system to operate anywhere in the world, on the road, and in the air. It accepted power supply at 50hz,60hz, or 400hz and delivered a steady 60hz to the compressor and fans.
NASA had very tight specifications on the allowable temperature and humidity excursions within the container, also known as the James Webb Telescope “cocoon.”
