Question

What considerations do I need to investigate for running multiple motors on one inverter?

Answer

Please review the following:


 Speed reference – all motors must be run at the same speed. They have the same frequency and voltage.
 Inverter Size – the size must be based on total current and not HP. If the aggregate is close, always round up.
 Motor Protection – an output line reactor and manual motor starters functioning as thermal motor protectors on each motor branch.
