So I finally had a chance to run all the motors. I could not get accurate data logs on them, as my Data logger was being maxed out. I saw bursts over 120 with all motors, but as I said, it's not really accurate, so I'm not sure just how high they went. I tried to log 1 battery in a parallel setup, and saw 91 amps, that would put the sytem at 182 amps, quite possible, but not confirmable. But also had trouble with the batteries not draining equal, so didn't feel safe doing it for all the motors.
Ran in my E-revo, geared 24/68 with Masher's 3.2, MMM, SPC 8000mah 4s. I have a hole in the windshield , for added air flow, and a dual motor mount, which gives more area for the mount to work like a heatsink, especially with the air blowing right over it. I ran each motor for around 20 minutes, of hard bashing off road. Radar was used for speeds, except with the Tacon, as I was by myself, I used a GPS. Ambient was between 70-72 for all the runs. I take multible temp readings, and don't just use the highest, but try to find the range it's going to run in. Generally by the time you're 10 minutes in, temps should level off.
Xerun 4168, 2250 kv.
Speed was 51mph
motor temp was varying between 120-125
The extra kv rating of this motor shows. It was the fastest, and felt like it. 5 minutes into it's run, the pinion came loose, so it got around a 5 minute break, it's temps might have inched a little higher otherwise.
Castle 2200. While my earlier pics showed the Castle version, I used the Tork version for testing. It has a little smaller overall can, but also has funky nubs, I guess you could say they act as cooling.
Speed was 49mph
Temp was between 115-120
I think the added strength of the magnetic field can be felt with this motor. It spools up a little smoother, and has more drag brake effect.
Tacon 2150
Speed was 48mph
Temp was 125-130
Spools up quicker then the Castle, but I saw no difference with torque.
So what can I say, all the motors perform very good at this speed. While they all have a slightly different feel to them, you'd have to run them back to back to distinguish them IMO. Though the other motors really need slightly higher gearing, to match the XErun.
My next test will be a higher load, I'll use some Big Joes, and see how the bigger tires and increased speed effects them.
Sorry I could not get more technical data, ;)
