I build and fly R/C planes Bertie, and use this brand of motor (EMP) a lot -- they have the shaft out the back so you can reverse the mount (sometimes necessary to fit in a cowl, etc.) On outrunners generally the bell is spinning (the part the has the magnets. |

ahh so that's how they work.. was rather confusing when I opened the box up and found the bolt on shaft! have never had one of these in my hands before. good to know who actually makes these motors, might make finding another one easier. I assume they are a reasonable make if you use them a lot? matthew, did you order the 6364 or 6354? iv just checke mine and I actually orderd the 54 version, glad I did as the 64 would be too long for the shaft! |
| mattinker:
Hi Bertie, I have ordered the 6354, I just checked my spindle, it's 100mm long, the 6354 is according to the specifications 55.8mm long, so I would have a little over 45mm to fit the bearings in. Thanks for the heads up! Thought full!! Best wishes, Matthew |
| bertie_bassett:
that's good, didn't want you to have the wrong one! you can get away with 51mm of shaft for the motor as the grubs screws are set back a little, that give a little more for the bearings. my original plan was to have the collet end of my shaft sticking out a bit further so you could actually get a spanner on the flats, however iv had to sink the head into the body and rest it right up against the front bearing. sinking the motor mount into the back plate gained a couple more mm too! |
| mattinker:
Bertie, So my two separate angular contact bearing may be an easier solution. I'd like to keep the flats accessible. Just a thought, the chuck is not hardened, you could drill holes for a "c" spanner a little closer to the thread. Post some pics so that we can see the progress! Regards, Matthew |
