5KW generator fan?

the fan is there to cool the motor,, no fan very soon no motor!!

the fan is probably pressed on so you would need a puller,,, if indeed it is welded to the rotor,, you need to get a rotor,,,,if it can be epoxied back,, use JB WELD are similar!! stuff is great and even works on plastic....

Is the frame of the fan broken or the fins? Is the fan of the removable type or is it epoxied to the rotor therefore making it part of the rotor?

Check this completed item on eBay. Is this the fan which you've broken?

The fan pulls air from the electrical panel end, through the windings and exhausts on the engine side of the rotor. If you could mount an external fan to the end of the enclosure to force air through it should keep the windings cooled.

sounds like you are as cheap as I am. Try epoxy, then buy a cheap fan plug it into the generator recpt and aim it at the space where the old one was. You will still be moving heat away from the windings and that is all you want, anyway.

i'm no longer particular if an epoxy may carry yet honestly properly worth a attempt, i'm no longer particular at the same time as to purchase it yet i recognize of an epoxy that could likely do the trick. that is a 2 area epoxy pronounced as (2-area TRA-BOND 2170T). Like I already pronounced, no longer particular the position to purchase it yet in case you'll get some i imagine you may get sturdy consequences. sturdy success...

there is always a way to fix something.... you could thread the end of the shaft and install a fan with a threaded center hole....

you could runt he generator without the fan

monitor temperature. it should stay below 200F. but check with the manufacturer

yes. avoid it at all costs. it is a danger and a major safety hazard. i suggest you just hold off on the fan until you have proper equipment.
