RC Tank Warfare community hobby forum

Hi to all,
I’m looking for recommendations for Low RPM (around 10,000 rpm) high torque motors.Reading through the forums I see that the Igarashi N2738-51 & Promax 400/480 motors come up quite often.
Any recommendations would be much appreciated.
Thanks in advance, Cheers Martin

If you Google "mabuchi specs" you'll get all kinds of charts on small electric motors and what kind of torque they have and what kind of RPM they have at what voltage and all the rest.

I studied these little Motors a couple years ago and found that it's quite an education. The worst part is that a lot of times the numbers on paper don't seem to match up with the performance of the tank. When I put the 360 water pump motors in the ztz-99 the paperwork all said it should run slower, but it actually ran faster. Those little Motors are a science unto themselves, so be prepared for an education.

As a simple rule, the greater the number of winds in otherwise same sized motors the higher the torque and the lower the top revs. The less the number of turns the higher the revs and the lower the torque. Things get a little more complex if you start looking at double or triple winds but l doubt you come across them for tank use. Wire guage also has a small impact.

The problem is that manufacturers rarely print the motor spec anywhere until you get into high performance 540 size brushed motors. An alternative is to use a brushless motor that's sensored and programmable as you can then set it up to perform exactly how you want it to. Unfortunately, these are not budget items.

Or otherwise you use an electronic board worthy of the name which will be able to manage idling correctly on an electric motor. The Clark tk40 or an Elmod can do it... If it is not enough, you can change the motors, but I did it few years ago, and it was worst...

Many thanks to all......
