WebMay 2, 2024 · Reverse rotation doesn't make sense. A generator doesn't spin backwards due to it being loaded. However, there is reverse torque due to current. The generator makes a voltage proportional to its rotation speed. The load the generator is connected to then draws current. You can't separate the generator and the motor inside the unit. WebJan 4, 2005 · This motor is used in small appliances, portable electric tools, etc. When you run your drill motor in reverse, you reverse the polarity of the field or the armature winding. This is not quite the same thing as reversing the polarity of the start windings on a split phase. There is also a permanent magnet DC motor which has no field winding.
