Can the speed of a 110volt motor , be changed without the use of a gear box?

the motor came from a floof buffer it has a 3 gear planetary for tourq. I want to slow the moter down so I can bend rodiron


There is two ways of changing the speed of an AC motor. The first is a gear box, which you stated you don't want to deal with. The other, and also expensive, is a frequency drive. This actually changes the incoming AC into DC then back to a AC that can be changed in frequency. This set up is used a lot in commercial AC applications.

Hi sorry but a lot more engineering is involved here the gearbox would not be the issue or slowing down the motor as a floor polisher has such a low powered motor. to bend metal requires a lot of torque especially cold and what sort of thickness is involved. hence why two things are usually done when bending metal a heat it up till it's cherry read hot makes it easier to shape and the second is done by hand as a blacksmith would do it. in industrial processes a hydraulic ram is used so it can control the amount of bend and increase in pressure can be done with a lager Ram. the reduction in motor speed with electric motors also tends to decrease the power in the torque of the motor. the most common method used with Ac motors is phase control which reduces speed and power and reduces power consumed as well.
