    The Voltage that comes from the wall is actually 240 Volts and wall plugs have 3 Pins NOT 2

    The air is first radiated and then (force) convected away (with the fan), right?

    It doesn't work and it's painful. Should the distance between the two magnets be equal to their distance from the center? Also, how many volts do you use in the battery?

    If i cut the wires going to the heater, would the motor be affected or would it just blow cold air? Or would I have to forcefully bend the bimetallic strip in order to get cold air?

    "So that you can see all the different parts of the motor" and in the end, you cant see shit. Geez, the level of stupidity in that logic instead of just peel the tips on the cover to take the motor out...

    I own an old brushed DC motor that needs overhauling. What happens if I replace the old permanent magnets (from the 60s) with modern and stronger neodym permanent magnets? Will it influence the general function of the motor (like power, RPM etc) or will it just increase torque?
