Caframo Ultimate 747/757 Fan Parts

In case you need a new fan motor for your Caframo Ultimate... you can search for part #RS-555SH-20120

There are a few models of 555SH and you need the one that has the drive shaft sticking out the front of the motor by about an inch.

There is a ptc resettable fuse f rx110f 48aj and two resistors (Blue, Brown, Gold, Gold).

The switch is:

5x On-Off-On Rocker Switch 3P 16A 125V RLEIL RL3-1 RL3-1-13-H-6-BK/BK-P5 21x15mm | eBay

The total cost of parts is about $7.

Also, there is a little rubber gasket between the engine and the housing to keep it from rattling. Mine fell out.

Re: Caframo Ultimate 747/757 Fan Parts

Zboss,
I'm having a problem locating the replacement motor 555SH-20120 for the 757 Caframo fan.
Where were you able to purchase them?
Didn't find them on ebay
Thanks

Re: Caframo Ultimate 747/757 Fan Parts

Ive just been researching this motor.

It is a Mabuchi RS-555SH-20120. Link to page decoding Mabuchi motor codes:

https://www.mabuchi-motor.com/produc...ignations.html

The first 2 nodes of the code give you all the physical characteristics, except shaft characteristics...which oddly are not included anywhere in the coding, but there are in fact a number of variations.

The last node is winding specifications. I have not been able to find the 20120 version, not even on Mabuchi's site (may be a custom winding for Caframo), but Im searching for other winding versions which would result in a similar speed.

You can find variations on the this motor on ebay.

https://www.ebay.com/itm/Mabuchi-RS-...edirect=mobile

This listing has the correct shaft lenth (19mm), but is a D type shaft, not a round shaft. Winding specs are not given.
