8.22 Fan motor (washer-dryers) 8.22.1 General characteristics The motor which actions the air circulation fan for the drying phase is of the single-phase asynchronous type. The rotor is of the "squirrel cage" type. The velocity of the shaft is approximately 2,800 rpm at a voltage of 220-240V/50Hz. 1. Rotor 2. Stator 3. Cooling fan 4. Pulley 8.22.2 Electrical symbol 8.22.3 Checking for efficiency FAN INOPERATIVE: - Check that the rotor is not jammed. - Check the pulley for slippage. - Measure the resistance of the stator. EXCESSIVE NOISE: - Check for friction of the rotor. - Check the bearings. - Check the drive belt. SOI/DT 2002-05 eb 93 599 35 23-17
