TP power motors

[ray schrauwen]

Oh, the 56mm TP motors (ones from hobby king) have crappy 3mm loose threads for motor mounting. I drilled & tapped mine to 4mm. I suggest doing this or using all 6 holes to mount those up. Unless you buy or use a cradle type motor mount, then it doesn't matter.

The TP power 2180kv 4082 has windings that stop short of the rear end bell by approx. 1/4" - 3/8". I don't know about a Leo 4082??

This TP motor has no front air vent holes and I may drill them out after I remove the front plate.

TP power motors, at least the 5692's I have also have windings that stop short of the rear end bell, maybe up to 1/2".

The 56mm diameter motors have 16 segment stators vs Leo with 12 steps. TP motors appear to have a much tighter wind of field coils compared to what I have seen inside leo 4074's and Leo 56mm diameter motors.

If the stators are wound tighter and wound better you may not need as much length in stator but, I'm guessing on that.

The magnet wire is of a different source I would say also being darker (maybe because of thicker enamel coating or different enamel colour coating???).

So far until the ice melts, I won't know much more.

Thanks for the Info Ray, let me know how the TP power 4082 2180kv runs

Not quite the same motor but i have a Leopard 4074-2200kv with the end caps removed & the winding is 1/2" short of the end of the can. Ill put up a couple of close up shots of inside the motor in an hour or so time to compare the Leopard with the TP you have. Martin.

Good idea with the photos. That will help me compare which one I should buy.
Thanks

Wow thats interesting, I thought the wires would be soldered on somewhere but not actually part of the motor winding?

That's why you can't shorten them. Castle has theirs soldered on so you can shorten them.

[martin]

Thats why on Leopard & a lot of other motors you shouldnt cut to shorten the wires as their part of the windings as well as the coating that is on the copper wire that prevents soldering conectors on if you shorten the wires. Martin.

Depends if it's a Castle or these other brands. These TP & leo, like Feigao & Neu have wires coming out that shouldn't be cut since they are part of the windings.

That "car" version of a 4074 loses that space for windings because of the wires exiting the side but, the boat version I bet is the same inside.

I have an Arc motor that has windings packed in like crazy from front to back, no wasted space.

So... Why shouldn't the wires be cut? Is the length of the wire leads contributing to the resistance/impedance in some way as to alter it's intended design??
I have cut leopard wires before, removed the coating from the wire and soldered bullets back on. No issues

The Arc motors are some of the best I have seen.

So now I need to see the inside of a TP!

[martin]

This is a car motor as it dosnt have the B in the code on the motor, I have been told by Leopard themselves that the 40 series of motors are not all the same inside. The boat ones have more magnets in them over the other 40 series, I also asked about other series motors 28 through to 56 series if they were also diff if the had the B designation & they said all the other motors apart from the 40 series are all the same motors inside & not diff versions. Martin.

I actually melted the plug where the wires come out of the motor on my 4074 due to a vibrating flex shaft and it over heated, now i know this ill definatly put some silicon to stop water that could enter the can!

I have a 4050 1160Kv in my MC w/240amp and run on 8s=
