Carbonbird 3100kv 2203 brushless Motor 180w 17g CW/CCW

Product Description

125w 17g motor with wide 22mm stator 2203 - This new 2016 motor and much thicker CNC shell case on the bell - to resist impact from FPV

Question - Whats the difference between this 125w Red, the Tmotor 1806 175w 1806 and 225w RaceSpecR on a Scarab Knife - which is best? It's a good question - the kv is speed - NOT the power - This 3100/2203 is optimised for 4S and 4" props on Scarab Knife 200 - it is best to use the recommended prop - adding a larger prop or a BS-Nose prop will likely cause overheating - the correct prop is the HQ4x4.5 tapered prop

Motor care and set-up

apply 1 small drop of Oil to bearings every 3 hrs with a syringe & dulled-down-needle ; use 20W50 new clean motor oil
DO NOT pull on the lead wires - not ever
Do NOT bend lead wires back and forth - risk breaking
Use short M2*5mm screws (excluded) - long screws will go in too far and CUT the windings !!! - risk - cutting insulation
Avoid hard impacts / Striking the motors - sudden impact can damage a motor if dropped / impacted /crashed - the magnets may be damaged / loosened

My motor suddenly stutters - was ok before? - Cut throttle - don't fly - Motors/ESC won't just stop by magic unless they are damaged/wiring compromised by mis-use

Motors are wound Delta - so each GBC has a pair of 2 small inner wires ; most likely one thread has been broken-pulled-bent internally if the wrong (too long) screws did not cut the windings
use a DMM https://www.carbonbird.com/products/uni-t-pen-sized-dmm
check the internal resistance Ω between all 3 input wires - 2 at a time - 3 readings should be identical 0.150Ω - what do you get Ω?
check to see if a lead wire has been broken - pulled - snapped off inside - visually look in
Noobs often mistake a motor problem for what is actually a broken ESC - physical damage to the ESC from man-force/crashing - make sure you have not broken your ESC

In some instances people have damaged their motors by letting FOD enter, something ferrous/magnetic get sucked inside by magnetic attraction force, from their work bench - then when they spin it up with the FOD spinning around inside :( (foreign object - damage) thereby cut the windings - be very careful with FOD

QUESTION - One of my motors stops before the others on shut down? How can i adjust it?

the shaft depth can be set any time in a few secs - this controls the friction setting - by varying the distance slightly between the circlip end and the grub screws (2)

a slight difference in friction has no real effect on flying - but can be set any time if needed

leave the motor connected to the copter - prop and all
- use a 0.05" hex tool - undo the 2 black grubs 1 turn CCW -
loosen the axial play of the bell by 1/1000" (freeplay) - pull the bell slightly out toward the prop
re-tighten the 2 grub screws.

Excludes

Excludes Props - Study the trust data above - 2203/3100kv is Designed for 4" props - recommended props are the HQProp 4x4.5 ; or - if you set your ESCs to MULTISHOT 14.4 (motors runs much cooler under MultiShot) you can also run the HQProp Durable triple 4x4.5x3 triples here - choice of props depends on Total weight. If you want this motor to perform best keep your Quad under the weights in the Quad column for 50% throttle. Remove weight. Be careful not to over prop or exceed amp limits above.
Excludes bolts - normally use the shortest bolts to sure the bolts dont penetrate the windings M2*5 Here
Excludes tools - a 9mm socket wrench/spanner is recommended to tighten the red nyloc nut ; grub screw 1mm hex (only required for full dis-assembly)
Excludes training - if you don't understand brushless motors - pls read the above

Warranty

Do not operate in dirt/dust - 1 year return to Carbonbird factory - Warranty specifically excludes damage caused by exceeding max amps limits or crashing, incorrect use of tools, incorrect pulling/breaking of lead-in wires, mis-use or poor lubrication of bearings* - claims for factory warranty require return of the product to us - at buyers shipping expense, for inspection - the decision of returns inspector is final.
