T p motors - problems

[GRAEME LOUW]

Hi built a RMCK Hydrolift 1100 and powered it with two TP 4060 1600 KV 4200 WATTS Max , two Turnegy 180 ESC , two 6 cells 4000 MAH Nanoteck lipos, 45-90 C . Two 82 mm stingers 3/16 flex drive shafts and two counter rotating Octura 447. I have run the boat about 10 times and have constantly got 110 km/h after getting CG correct as well as stinger angles. BUT I have now blown two of these motors.The magnets have come away from the stator or armature and jammed as a result have blown the esc.
TP REPLACED THE FIRST MOTOR BUT ITS NOW HAPPENED AGAIN. My rpm is way less than their stated 50 000 rpm.The last motor I blew has jammed so badly that I cant get it apart even hitting with a light hammer. Its totally solid. All the binding holding the magnets in place has come away. The bearings seem to still be OK.

Why is this happening! Can someone please help.
Thanking you
Graeme

I'm not too sure as to the ACTUAL reason but it would seem that they may have had a bad run on their quality assurance given that you wouldn't be going over 35520rpm? It would be good to know if they are having quite a few returns of this particular spec motor as it would likely be the whole production run (as with most manufacturing companies) until the fault is corrected?

Just putting some ideas out there... Not good for publicity whatever the reason.

Just my guess/2c.

Oh dear,that's not sounding good!
I have got the exact same motor in my Fightertcat Cheetah running a single 6s set-up with only five runs.
what's TP saying this time.

The production run may be for 1000 units at a time for example, and you may have a motor from the run before/after; or the motors that Graeme is running may have some sort of external factor that none of us are aware of...
I just put forward an example of what MAY be the cause and I hope that no-one else has the same issues.

In any case, you're running a 4092 in your sig so if thats the case, it would be a completely different production run - being a different length etc...

I bought two at the time but sold one im pretty sure that the guy that bought my other one has thrashed his to bits for months on end on a 6s setup without any problems.

The TP 4060 motor is a 40mm x 92mm same motor.

One thing I did notice with this motors was that the wires were not insulated to well going though the housing so I over-covered mine with some silicone tubing just in case they shorted out when they get some heat in them.
Im sure when Ben was at FC he said the same.
just a thought.

[GRAEME LOUW]

I also re insulated the motor wires before running them.
Really dont have any clue why they both blew as RPM no where their max spec of 50000.
For me to send another motor back to China is really not worth it as I am in South Africa and with the rand /dollar exchange it becomes too expensive.

Good to know, was considering a TP motor for my new hydro, think I'll just save for a while longer and go back to the Neu plan.
This forum has helped me so many times trying to decide on the next purchases.

Graeme,

The plain truth is that the TP motors do not have the quality of other motors. Some motor vendors randomly select the max speed of a motor based on what everyone else claims, not by a calculation let alone a burst test. Save you money and invest in a proven name.

I've had two Leopards of the same size with the same T180 ESC's fail on 6s . Both ESC's were blown.
I personally think it's the ESC's that blow first & take the motors out.
When you say in your first post that you were running 2 x 6s 4000mah packs, is that per motor, or is it one pack per motor?

I have run my TP 40-92 1600KV motor on 8S for a while (SAW attempts, it was too slow.) and it is still
holding together nicely. It is presently in a 39" mono hull set up for
oval racing on 6S2P power for next season.
sounds like it might have been a bad batch to me. JMO

I have bashed all my tp motors never had a issue got them in boats and buggies i just love the power and torque they deliver i have had better luck with them than i have leopard motors sounds like they just had a bad run i mean look at castle the problems they have had with esc's latley they had a bad run and had allot of failure it happens to everyone if you do it long enough dont give up hope you get it worked out

I am running one battery 6 cell 4000mah per motor. I now have one motor thats working so it makes sense to buy the same again to get the boat running and try again. A lot cheaper than buying a whole new setup. Its very difficult to deal with TP as they battle with English and I cant speak Chinese. They were good last time and replaced the motor. Race Mechanix is correct and buy quality but in South Africa once you take the rand/dollar exchange rate and transport and it becomes very pricey. !!!
I listened to what he and Fluid and some others said a while back and bought a Castle 2028 motor for my conquest and have been very happy
What a motor. I will send another thread re the conquest later on as I still have a few issues with the setup but it is doing 60 mph
Chat later
Cheers
Graeme

Better buy a pair 4050 from TP.
Probably the shaft wobbles on 4060 and the magnet brokes.
Over 82mm motors must have 8mm shaft.
