Now that would be the best way to tech a sealed motor ...  just add a degree wheel (indexing flywheel) to check the timing..

 

Nice Item, congrats on your innovations !!!

This would have made a great tool in my slot arsenal. But since I will no longer be allowed to take these measurements on my Puppy Dog arms the tool is useless to me now. Sad :frown:

Why can't you take any measurements on your PD's? I'm pretty sure you can use this on an assembled motor. You might have to connect some wires to the little pads but that shouldn't be too hard. Tracy, can you take readings through the brushes or is that a bad idea? Is there any way to re-calibrate this in-application or does it need to be connected directly to the commutator?

I was thinking of a way to take the measurements through the hoods. Would need to rig up probes.

Rules will never stop racers from trying to get an edge.They just make us work harder.

 

I've got lots of work to do on chassis and driving skills first. The motor is only a piece of the winning puzzle. Putting the puzzle together is the fun part.

Note to get good repeatable readings ... first you need to check all the same type and winds together. Put all the arms you are going to check in the same area for a couple hrs. so they all come to the same temp. Very important! If you read a arm and it's 75 deg. and your friend comes over with the same type arm that has been in his car all day and hot his arm will read much higher!

 

Trying to meter thru the hoods or brushes will give crazy results. I sold Front Line Products meters years ago. Trying that did not work with solid repeatable results at all. When we developed my meters they would read the heat resistance gain even if you held the arm for 30 sec.-1 minute in your hand.

 

I sold a wire wound calibration resister that was used to set 0 at any temp. You put the resister with the arms in the same room long enough to all come to the same temp before you read them.

Tracy does pressure on the comm change readings?

Ok I am going to tell you how to use my New Arm Meter on a PD Motor after reading the rules and talking to a few people. Here is how you do it,Buy you some new arms check them with the arm meter find the best one and then send that arm with a seal motor to rebuild and tell them to put the new arm in the sealed motor and that's how the fast guys get fast.You guys ask how to use the Arm meter on a PD Motor and this way will work.                                                        

(PS -I am going to take a beating for this one ) :D

What readings would tell me the differance between a 75W and An 80W puppy

I don't know what the reading would be but the 75w will have the lowest reading of the two

That would be a good question for ProSlot. 

 

Matter of fact, it would be great if all arms are metered from the factory as a QC check.  If they don't make the grade, they are taken apart, and fixed until the numbers read right.  It would eliminate the dogs out there...

Tracy,

 That is exactly what I planned on doing. It will leave some arms in limbo but it solves the entire quagmire.

 

 Thanks for the great products.

Would not the 80W since it draws more current and should show better resistance readings I believe.....??

75W and 80W were referring to winds, not watts.

DUH..... Half asleep...  75t will read lower....

This is just one tool to see what your arms may be capable of but resistance is not everything....

 

My electronics geek built me a machine years ago that energized the field on our arms and used a hall effect probe to read the field each coil produced..... no, it did not "heat up" the coil since he used AC to do it ...somehow... never understood how that worked ......

 

It worked very good and you could see that each coils field.  This showed how efficient each coil was .... That explained why some arms that read low resistance still never performed.  He was a R&D guy for Beckman Instruments ..... wish I had that test machine now but he passed away and had the test circuit and his wife never got hold of me before she got rid of all his stuff...
