    Hello, I have such a problem. I have a standing fan at home and it worked beautifully until it suddenly stopped spinning, so I took it apart and when I turn it on low speed it buzzes as if it wanted to spin and the same at medium and high speed. So what could it be?? there is something about the engine Standing Fan Not Spinning: Buzzing Sound and Burnt Smell - Possible Engine Issue? and there are two cables coming out of it and I don't know what it is, but before the engine stopped working, when I was carrying it, I smelled something burning. help. Thanks in advance for your help. Greetings

    Read the points: 11, 11.1 of the regulations - and correct the title.

    Hello, this is a capacitor, perhaps it served as a starting one. Show pics of the whole engine.

    Try to turn the axis of the rotor (without the propeller) it should rotate very easily, if you feel any resistance, lubricate the bearings with e.g. WD-40 liquid.
    If the rotor rotates slightly, there may be a short circuit in the winding or a power outage (one of the wires likes to break.)
    This motor has two windings, one powered directly from 230V, the other through a capacitor, check if any of them are open.

    the rotor is light, this fan has 3 speed levels: small, medium and large, I checked the winding and it has a transition. How can I check the capacitor?

    You can't check a capacitor without a capacitance meter.
    The burnt winding will also have a transition, so do not suggest.
    As in all 3 gears, it's not 99% a blown capacitor.
    If you have a household appliances service somewhere close, you will get such a capacitor there, probably in a different housing, because this one is non-standard, it does not change anything.

    If the capacitor is blown, pull it out and connect it without. If the motor is in good working order, it should start after giving it the right direction of rotation.

    Should I connect the wires going to the capacitor?

    In no case , just turn it on and push your finger for momentum.

    Hello, I have the same problem, one of the capacitor leads broke off during the integration, the fan runs but you have to replace the capacitor, in my case it is 1.2 uf _+5%c459v-ac and looking on the Internet I found a slightly larger one, 1.5 uf, can it be or must be 1.2 uf

    Added after 1 [minute]:

    Capacitor labeled CBB61B, with specifications 1.2uF ±5% C 450V AC, held in hand. .

Topic summary

A user reported that their standing fan stopped spinning and emitted a buzzing sound along with a burnt smell. Responses suggested that the issue may be related to the capacitor or motor windings. It was recommended to check the rotor for resistance and lubricate the bearings if necessary. The capacitor, which may be faulty, can be tested with a capacitance meter, and if blown, it should be replaced. One user mentioned a specific capacitor rating of 1.2 µF, indicating that a slightly higher rating (1.5 µF) could be used as a replacement. Caution was advised against connecting wires directly to the capacitor without proper checks.
