wonder if we could get someone else to give a third opinion see if we can't get some consistancy.

Guys,
I just verified that the Motor Master is working properly based on some other motors I have saved data for. No changes on those and the data is right inline with published specs and other tests I've seen.
I am wondering is the Motor Master is simply having problems with this particular motor spec. Perhaps it is at the very limit of its ability to read accurately???
I can send a motor to someone for them to test and see if it matches my test results. If someone has a Motor Master I'd be really interested because it would be great to see if the results are the same or different on another tester of the same type. At least that would indicate if my machine is off.
BTW my Platinum Motor Master has V3.2 firmware in it. Maybe an update is in order??
Thanks again,
Greg

I have a Much More Motor Master Surikarn (sp?) edition. I tested my 70t and these were the results
4.8v
23,750 RPM
0.46 Amps
If you are pulling anything significantly higher than that then your motor is damaged in some way. 3 amps is pretty gnarly, my really hot handwounds (less than 20 turns) pull less than that. I would ask Philip about it, maybe an exchange or something is in order. You also may have a bit too much comm fluid on there, I have seen that do some strange things to my motors before.
I didn't do the step testing, I just used the motor test function at a steady voltage. I would retest, but I had to send the motor back (for another issue).

1st motor tested,ive done this one staight out of the packet for comparason against break in and most people just whack them in
tested on much more surikan v3 motor master with regulated 3A power supply,
23520rpm @4.8v
max amp draw .45
average amp draw .36
overall first impressions,
exactly what i expected from a top manufacturer like PN.
good build quality(no loose endbell,brushes centred)
bushes are fitted squarely,motor shaft moves free with about 1mm end play.
well balanced arm,no nasty vibrations or exessive noise or heat.
nice neat winds,fat comm and trued well
2nd set of results
motor 1
50min break in @1v with wd40 on bushes and comm
23910rpm @4.8v
.45 and .22 draw
motor 2,
same break in as above
23640rpm
.45 and .37a draw

Thanks for the ideas.
Well, it was not just one but all 5 of the motors I tested so I think the Motor Master is not reading properly for some reason.
As far as comm fluid that is not the problem. The readings were virtually the same before and after and I use very little.
So, I am getting another Motor Master and I'll report when I get that.
Greg

I posted this over at the HFAY Season 6 thread too but wanted to leave the info here as well.
Guys,
I got a new Much More Motor Master the other day and sure enough, I am getting much similar results to the rest of you on my HFAY Season 6 motors. Sorry for the initial misinformation!
I was able to re-test 3 out of my original 5 motors.
If you'll remember the old Motor Master was showing a 3A draw!
Retested HFAY 70-Turn Motors
#4
22,800
Peak Amp .42
4-step Ave .20
#1
23,330
Peak Amp .63
4-step Ave .37
#3
23,400
Peak Amp .67
4-step Ave .35
I also noticed the RPM on each motor was about 700RPM less. Curious!
Now, to find out what is wrong with my original Motor Master. It is going in for a check up.

FYI
I have 2 of the motor from early last summer.
Both have had the comm wear down before 1 set of brushes is worn out. The com is wearing a grooove down from a fat comm to a small comm
One has completely died, The dead one looks to have lost ~1/16 inch from the comm.
I have never seen a comm due this before. and I have 2. Keep an eye on your comm for wear.

I just finally changed mine out from the original one I got. I've ran it for almost a year, including all HFAY Events, all our club races and two 1 hour endurance races. Not to bad for a motor that only cost $8.50

After all kinds of race abuse, mine are still going ok. I've been spraying them out after every race though. I do see some comm wear, but the brushes on one of the motors are pretty much gone! I will have to order new motors very soon.

the comm wear though me for a loop. I alway kept an eye on the brushes. for the comm wear you need to look through a diifferent hole in the endbell
