11.7.6. Heater electric motor
The scheme of turning on of the electric motor of the fan of a heater and the electrowarmed back door window
1 – generator;
2 – rechargeable battery;
3 – heater switch;
4 – additional resistor;
5 – switch of heating of a window of a door of a back;
|6 – heater electric motor;
7 – heating element of a window of a door of a back;
8 – ignition switch;

On cars the electric motor 51.3730 - 10 of a direct current with excitement from permanent magnets bringing the heater fan into rotation is installed.
For change of speed of rotation of the electric motor on a casing of a heater the additional resistor 17.3729 is installed.
The electric circuit of turning on of the electric motor of the fan of a heater is shown in the drawing.
