This topic may not need a full page to discuss, but at least it can stand as confirmation that it is in fact an easy choice.
In days past with DC motors popular there was a choice in motor controller to use. DC motors are largely interchangeable so you could pick whichever motor controller you wanted to use as long as it was sized correctly. Unfortunately AC motor controllers must be designed (or at least tuned) to a specific motor. This unfortunate part does simplify the process quite substantially though.
Which motor controller should you use? The one designed and used in production with your motor.
