Does an AC electric motor with no load consistently draw its maximum power at full RPM's?
To a first approximation, the motor draws as much electrical power as it is doing mechanical work.

If there's no load, the power consumption will be low.

In practice, there are electrical and mechanical losses involved in keeping a motor energised and spinning. The motor might also have a fan for cooling itself. These will require some power.

Finally, the motor efficiency will be less than 100%, so it will require slightly more electrical power than it produces mechanical work.
