Because of the timing of the magnetic field with respect to the brush orientation it is not recommended to just reverse the polarity of the electric motor to run it backwards. This will cause the motor to run hotter than normal, it will be less efficient and its life will be shortened. To safely run the electric motor in reverse you would have to adjust its timing, which is only possible on certain motors. If the electric motor you have does not provide instruction to do so, then do not attempt to reverse the direction of the motor. Purchase a reverse direction electric motor for your installation instead, or consider a different gearing combination to provide you the right end result.
