Sadly, while you do have the right idea, the inverter you can buy for $40 will certainly not have the required ampacity to handle the necessary current.
Therefore, you could build your own conversion circuit: http://engknowledge.com/power_supply_design.aspx
or go out and buy a DC motor.

Need more info, such as current or power rating of the motor. The inverter has to be sized for the motor power, but about x3 as the startup current of the motor is much higher than the operating current. I think you will find that the inverter gets expensive, and heavy. When you add it the problem of controlling the motor speed, and the increased shock hazard, you will be better off getting the proper DC motor. .

a dc starter motor off a small plane would be better . or try using the dc starter off a car .
