    1ph to 3 phase inverter

    I have been asked if I can wire a motor for a car lifter in a domestic garage, however the motor is 3 phase and only single phase is available in the property. Is it possible to use a single phase to 3 phase inverter to power this motor? I will attach photos of the motor and its output.

    So, the actual job is on a farm. I think I'll keep things simple at the moment and just ask about voltage drop. I'll come on to earthing and bonding a bit later or on another thread! We have a 3 phase supply (100A p/phase). From supply to first barn (we'll call it Barn A) is 70 metres. For...
