Allan Bowker Posted February 25, 2010 Share Posted February 25, 2010 I bought this motor from a swapmeet and the seller had no specifications for it. So for £4 I thought I would give it a go in a depron plane. Can you help identify it please? I need to find out what voltage, prop size, kv, etc I'm dealing with. Identifying this could save me a burnt out motor.

Allan Bowker Posted February 25, 2010 Author Share Posted February 25, 2010 Some dimensions might help! Edited By Allan Bowker on 25/02/2010 01:42:28 Quote Link to comment Share on other sites More sharing options...
Bert Posted February 25, 2010 Share Posted February 25, 2010 Allan The only sure way of doing it (without a lot of bench testing) is to use This Otherwise I would start with a 2S Lipo and a very small prop and give it a short run checking the temperature with my finger (be careful) and up the size of the prop in stages checking the temperature every time. and then go to 3S and do the same until I found the largest prop at a reasonable motor temperature.

Andy Gates Posted February 25, 2010 Share Posted February 25, 2010 22-15 does not sound right. The diameter length ratio is not right, although I stand to be corrected. Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted February 25, 2010 Share Posted February 25, 2010 I found an A2217 motor which fits the dimentions. Can you give us the shaft diameter please? Please however, do not assume the specs are correct just because the size matches since motors can have different windings, in wire thickness and length inside the same size casing Quote Link to comment Share on other sites More sharing options...
Allan Bowker Posted February 25, 2010 Author Share Posted February 25, 2010 Good point Andy, it did occur to me that might be the case, so I will be monitoring it very carefully. Just tested this on a 3S battery driving theGWS HD-8060 8x6 Hyperdrive prop and it was running at 175watts @ 15amps peak. Quote Link to comment Share on other sites More sharing options...
Allan Bowker Posted February 25, 2010 Author Share Posted February 25, 2010 Just measured the shaft and it is 3mm in diameter.Edited By Allan Bowker on 25/02/2010 19:34:44 Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted February 25, 2010 Share Posted February 25, 2010 That does not quite fit the motor I was looking at which is good for 200w input. 175w may be a little close to the limit allowing that it is on a thinner shaft. I think I would aim for the 150 / 160w as a guide. Quote Link to comment Share on other sites More sharing options...
Allan Bowker Posted February 25, 2010 Author Share Posted February 25, 2010 Just ran a 10x5 APC-E on it for a good 10 mins varied mid to full throttle (3S Li-Po) I got an average 200watts and 20amps, glad to report the motor was luke warm. Happy bunny so far Quote Link to comment Share on other sites More sharing options...
