I have a 6-months old Fantasia ceiling fan (mains powered, with 6-speed reversible dc motor) which is causing a lot of interference on MW.FM

you can try and put a AC line filter as close to the device as you can , 3 wire AC feeding is better ....
DC motor may need bypass caps , which might be a problem for the 6-speed driver....
The clamp on fairrite or a core should be on everything in a ham home, and all overhead AC drop lines IMO.
the type 75 cores are only about $1 and go after all the noise below 1mhz ( that's is where most of it comes from )
you may be able to use the AC line filters on DC if amp rating is enough ( leave a little margin here... )
tips from a solar-powered ham radio operator.
