| + | [title] The guts |
|---|---|
| + | [* black] The primary assembly has a metal tube which directed the hot air out of the nozzle. The tube enclosed a heating element spiraled around a framework insulated by a heat resistant paper. The heating element is essentially a resistor wound around a synthetic thread that resisted burning. |
| + | [* black] The other element of the assembly was a brushless DC motor. The input AC voltage is put through a 4-diode full bridge rectifier with a smoothing capacitor before the DC voltage is fed into the motor and the resistor. The DC motor is attached to a plastic fan which drives the air through vent holesand down the metal tube across the heating elements |
