I got it and noticed that it doesn't spin freely like the other cheap motors. Why is that? It turns a lot harder, you can really feel the magnets when you turn it.

torque from the 4 poles...

have you installed it in your truck yet?

once you do you will see why.

these things are amazing.

Mine was like that, but once installed it is sweeeet!

I think it's mostly to do with it having a slotted stator.

^ +1. Motors with slotted stators have a greater magnetic attraction since the magentic field is being concentrated via a metal core. But, since the field is concentrated, the rotor range where this attraction is strongest is smaller.

I could have explained it like that if I wanted to.

Of course, I just thought I would expand on your initial statement...

Is this a Neu 1500? My Neu 1900 also cogs heavily and have been curious to know if the 1500s are the same.

I think my Hacker C40 is the only free spinning motor that I've seen before...

I haven't had any cogging with my 1515 1y.

I don't mean cogging with power. I mean free spinning, with no current flowing through the motor...

I have not ran it yet, waiting for my esc to get repaired, I blew both my quark and MGM :(. I think my quark will get here next week.

How have you blown your MGM

4 other guys at racing have been running MGM's, 3 of them have burnt out MGM's.

My emaxx is too heavy, 12 lbs. I run 5S in the sand, and race. One day it stopped, the issue was that the motor was cooked. I didn't know this, and kept trying things with the ESC. Once I figured out it was the motor, I put a new one on, 10xl. That one ran great, until it started to smoke one day, and when I put the temp gun on it, it was 300 degrees.

I put an 8xl in, but ran a low gear, and set my radio EPA to 65%. That setup ran fine for a while. While I was running in the sand racing it stopped. From that point on, the ESC would not turn any motor. To test that, I got a motor that another ESC could turn, but the MGM would not, and no beeping. So I'm not sure if it was my killing the motors or what.
