View into a Neewr/Rocket Motor, TP Power

[florianz]

Hi there

during the past 10 years I had different brushless motors, like two-pole toasters of death, and good ones like the losi xcelorin or Medusa Afterburner.

Last autumn I probably have roasted my small TP Power 3670mm motor, as it killed the cheap sky rc ESC. I also have a 80mm TP Power Motor, which is too big and heavy for my light Tekno Truggy.

So in the following, I wil post pics of the (probably) dead TP and the new chinese motor, pics of the MBP will follow.
The chinese motor is a D-wound, same is the TP, the MBP are all Y-/star-wound.

So lately I have got myself a replacement for the small TP Power Motor, the motor is named after a shop in Germany "MBP 3645 1800kv". The MBP looks a bit like the TP, but has a longer rotor magnet, I think almost 50 mm.

But actually, I wanted to get an other motor, 4276 Motor, which you can get as a Rocket, Neewer, TeamMagic motor, but is not available in Germany.

Here I have read about that motor

But as you can get that motor in Germany at CS Elektronik, I now have two new brushless motors..., which I will compare against each other.

According to that old tradition of mine, I will post some detailled pics.
So like that we have a comparison of a TP and a noname-motor.
What I loved about the small TP is the massive torque, even that it is a 2000kv motor, so in the next weeks I wil find out if the chinese motor can hold up with the TP or the MBP. In that case, Size does not necessarily matter.

Pics of the neewer/rocket/bison:









TP Motor (Format 3670 mm,36407d 2000kv), packed with copper

there u can see a dark burned spot




comparison of the magnets, both have about 18mm diameter; the TP is heavier. The MBP Rotor (no pics yet) has almost 19mm in diameter.


As you can see the tp rotor is longer, the other measures 40mm.

The MBP-magnet is even longer, pics of that motor I will post later.

During the next months I will be able to compare these two motors; I had a short run with the new MBP-motor, looking good I think. I run these motors with 5s, the Bison has 1700kv.

I will probably sell my 80mm TP motor, too big an d heavy for my quite light Tekno truggy.

Overall-quality of the chinese-motor is pretty ok, probably a bit better then a Leopard, especially the magnet.

Looking forward to your replies!
regards,
