hello. i have a air conditioning that uses avaporation and a fan to cool down the room. my fan motor is died. i opened it and windings are burned out. its 200 watt motor 4 poles. it was having 280 turns in each pole 0.3 mm wire diameter. so i bought the wire and i made the windings. i tryed to insert the windings and i just could not do it the slots are too small for 280 turns to get in. i could not do it. so i reduce the turns to 230 and it barely fit. anyway another problem comes in. the motor draws about 4.23 Amps from 230 volt line. i pluged it in and the windings start to heat up so quickly after couple of secons smoke come out. the thing is 0.3 mm wire is not rated for 4 amps. its rated for 1.4 max. i measured the total resistance of stator it is 48 ohms. which is normal for the 230 turns winding. in each winding 12 ohms. well 230/48 =4.7 Amps.
my question is how was the original motor winding worked out for so many years ?
well yes i reduced the turns to 230 turns but even with 280 turns total resistance is going to be 59 ohms. its still 3.89 Amps that the wire cannot handle. how is this works out any information and ideas are appreciated. and sorry for my bad english.
