Can one single inverter (AC drive) drive multiple motors?
Yes. Connecting one single inverter (AC drive) to multiple motors is actually quite common in certain industries. In fact it is a cheap way to obtain speed synchronisation between the motors. But please remember that it's limited, of course.
Make the settings under the following condition:
Inverter (AC drive) Rated Current should be larger than or equal to Motor Rated Current x 1.1 (at continuous operation)
Check whether the current is within the inverter (AC drive)'s overload capacity at maximum load. Electronic Theermal relays cannot be used, so install a protective Thermal relay for each motor.
And there's another factor you should remember. All of the motors connected to the output of the inverter (VFD, AC drive) will start and stop together, and will operate at the same speed.
And don't use contactors to start and stop the individual motors.
