it could overheat and become damaged if it is driving a high torque. Much better to use a gearbox.

Which motor is superior in efficiency and the most extensively used of all types of electric motors?
Motor efficiency depends on the motor size and how much it is loaded. You get the best efficiency above 75% of the rated load for that motor. Note the table below: Horsepower Standard Premium Efficiency Efficiency% Efficiency% 1 --- 78.0 --- 82.5 2 --- 78.5 --- 84.0 5 --- 84.0 --- 89.6 10 --- 84.0 --- 91.1 15 --- 87.5 --- 91.7 25 --- 90.2 --- 93.0 50 --- 91.7 --- 94.1 100 --- 91.7 --- 95.0 250 --- 94.1 --- 95.8
Why does my AC single phase motor run for a while then stop?
Look on thew nameplate of the motor to see if it is thermally protected. This means that there is overload protection on the inside of the motor next to the windings. If the temperature rises in these windings the motor will trip off line and stop. Once the motor cools down the thermal overload device will reset and the motor will start again the next time you try it. As the answer states below reduce the load. <<>> How about over heating. To much load caused by bad bearings. Simply to much load.
