When a motor is rated for 3hp that means it can safely sustain a workload of 3hp without overheating or being physically damaged, not necessarily how much power it will draw.

Actually the 2200 watts is being very conservative and assuming that it is not delivering peak power. Peak consumption of a 3 hp single phase motor would be closer to 4080 volt-amps, or a draw of close to 17 amps at a voltage of 240 volts.
Way more money in electricity than most people including myself would be willing to pay.
