MMM 2200KV sounding like a Electric Drill ??

[sabongi]

Just got my MMM, took it out of the box, installed EC5 plugs and ran it.
Motor is making a electric drill sound, something like a really bad bearing or something.

What can i do?

I'm in Brazil, so it would take 1 month to send it back, and probably 2 months to receive it back from you.

Can't afford waiting all this time. Is there something i can do?
Bearing oil maybe?

[nvtuning]

if your rotor isn't damaged and you are willing to drive again soon buy a new bearing others you wil need to contact tech support

Both are/have electric motors and may sound alike.
Did you run the 2200 installed in a Rc or just holding it in your hand?
Does your electric drill run okay or does it get hot and smoke?
You can take the 2200 apart pretty easy to take a look around inside. Take the front end bell off and install a pinion(for grip and to hold bushing on shaft) then slowly and strongly pull the rotor out. Note the number of bushing on the shaft on both sides of magnets. It should have some clay on the end of the rotor where it was balancing.

I have a CC 1512 1.5Y that has a distinct "click" over one spot in the rotation of the rotor. Took it apart bearings fine rotor looks ok to me. Any ideas?

It was in my hand!
Runs ok, no heat or smoke!
Took it apart, only one bushing on the front and another on the back. Bearings look ok.
Anything else?
Maybe too much axial play?
Maybe the brass bushing size is wrong?

Are you reffering to the noise that a cordless drill w/a clutch sounds like?

I thought you weren't supposed to run them with out having them installed in a vehicle!!

Uh dude, I hate to tell you this but you NEVER want to run a brushless motor without any kind of a load on it. I think you just blew the bearings

[sabongi]

i never got to full throttle, just below middle...

Actually running the motor with no pinion at WOT is required for the new motor/kv test.

Personally
I think he blew a diff.

[sabongi]

The motor was in my hand... out of the car...

[bryan]

Please attatch pix of what you are doing.These motors are very "notchy" with no power applied.Or FREEZE may be right and you did f up a bearing?

In the castle link software when you do the KV motor test it tells you to either pull the motor away from the spur so there is no load on the motor or just take the pinion off the motor.
