rotational speed (as low as 0 Hz/0 Rotations Per Minute (RPM)) and 60 (VFD), motors can be run at higher than 60 Hz, known as an overspeed condition, typically as speed would only be 50 of the output at 60 Hz Other factors such as
Overspeed Motors May Technical Bulletin
If the AC frequency is 60 Hz the motor will rotate at 3600 RPM (60 rotations per second times 60 seconds) At 50 Hz the rotational speed will be 3000 RPM and at 30 Hz it will rotate at 1800 RPM
