Single phase electric motors has a start winding built into them. They can be capacitive or inductive in nature. You reverse the start winding leads with respect to the stator windings. Stator windings are the wires you see when you look into a motor.
Usually motors that can be reversed have the connection diagram on the case or hidden under the cover where the wires are connected.
If the motor has a pulley system on it, it probably will start OK provided it is a speed reducer.
