While a transformer can step down volts, it can not change the Frequency. So there will be some kind of humming noise when you use it with a transformer.

Transformers are prone to humming on their own (even without load) due to magnetostriction and other reasons. I am puzzled: how does frequency difference cause hum ?!

Frequency difference can, of course, affect clock and motor speeds and such. The 60 Hz appliance the OP is planning to use, would run slower at 50 Hz if it has a motor. Whether that would still be within acceptable limits, only he can decide.

The transformer will work fine. It is the device that might be affected. The capacitive and inductive resistance (or reactance) are related to the frequency.

Capacitive resistance = 1/ C*2*Pi*f, Inductive resistance = L*2*Pi*f (f is frequency)

So if this device (of which i am not aware fully) runs on AC then the internal device resistances are affected. The increased hum will be from the device.

Any recommendation for a good BLDC ceiling fan? Had seen some earlier posts on issues with Atomberg. Is it still good? anything to watch out for?

We have 11 Atomberg ceiling / wall fans with a mix of IoT and remote controlled ones, and they are pretty reliable and classy too. Only thing to note is that the 1200mm blades don’t have a great throw. The 1400s are better.

Still, well done you for even thinking of composting. If that is what you're doing, composting food waste?

Food only but ditched the plan now.

You should be able to source one easily in Bangalore

I suggest that you get the second type. Just be sure that there are two coils and not the run of the mill auto transformer type.

Chickened out of the plan for now. Many many thanks to all of you for the tremendous input though!

Was gonna say, if it's food waste only you want to deal with and want minimal hassle there might be a solution.

Do you have access to an outdoor garden? We've gone for a low effort solar solution. A green cone:https://greatgreensystems.com/produc...5s-y49FpJbMS9R. Bit of a pain needing to dig a deep enough pit to get the basket bit sufficiently low enough that it becomes harder for vermin to get at it. It's great in that it can pretty much take all food waste, including fish and meat bones. I'm sure there must be similar solutions available in India. If not, it's really simple as a contraption. ABS plastic basket that uses some washers to connect to the above ground plastic cone, it too made of plastic, and then that's it. Got a little twist locking latch for the lid.
