HobbyKing® TURNIGY® PropDrive brushless motor manufacturing

See the steps taken to ensure quality and performance in every PropDrive (NTM) motor produced by HobbyKing.
From magnet placement, wire turning (performed by engineers) through to dynamically balancing and final Dyno test on every single TURNIGY® PropDrive Motor.

Definitely have to make more behind-the-scenes videos. These are just as entertaining as the reviews and flight videos.

Cool to see some 'behind the scenes' of production footage. Thanks!

Wow I really like this! It would be really nice to see more videos like this, showing how things are made at Turnigy.

Great job hobbyking - very interesting to see!

Hello "rapz0r". I buy 6 "NTM3548-900KV" for a Hexacopter and really impressed me the power of these engines may not be highly efficient for its low price but I prefer them. I think it is the best engine that produces Hobbyking. congratulations

The only detail is that in a short time are oxidized by the letters (where the laser removes the paint to write on the casing).

Hobbyking should correct this problem because you can lose balanced to grow oxide layers.

Nice of them to share this video.. thanks!

[AdamPotts]

Probably one of my favourite ones out there, especially 0:39!

So, would it be possible to get printout of the curves for that ONE motor(and not some other) I receive if I order one?

[HobbyKingOfficial]

@rapz0r NTM's "PropDrive" are totally in house, HobbyKing is able to monitor all materials. QC begins from stock/material arrival, right through to final Dyno and balance.

Hello, I have been a major fan and customer of bldc motorsWhile going through some of the turnigy outrunner I have I realised the external case of the motors are non magnetic, acting as a magnetic shield from the neodymium magnet inside. Please can you help me understand the principle behind the case shielding the magnetic force or is the magnet single direction biased? Thanks for your prompt response. It will help in my school research. Thanks.

I use ntm on everything i can. My favorite of any motors.

[HobbyKingOfficial]

@rapz0r NTM's are priced lower because we produce them completely in-house.
NTM's are the best motors we retail at the moment.

[HobbyKingOfficial]

@Shinyapplz 30% of motor cost is attributed to salary. These arent sweat shop motors which would be around 10%

[HobbyKingOfficial]

@poerik not at all. The power curve on this is great.
The Dyno continues to load the motor until it stops.

Ok, so these are NTM motors, I am interested in seeing a production line for Turnigy XP/SK motors. Because so far out of 4 motors I ordered only one was without bearing and/or magnet problems. The price of these NTMs is pretty cheap, even cheaper than a lot of TGYs so I wonder how the TGYs are made and why not like NTMs?

Regards

As you can see from the video, the motors are built in teams by engineers, not on a production line.

[BashMonkeyRC]

Remember, there's always a lemon in the bunch. There's always bound to be one motor with a bad magnet or unbalanced that for some reason happened to speak past testing. Be glad they QC test each motor.

@itchyliabdo Those conditions were much better than I expected to see. Cool video though. Shows us the engineering behind the Turnigy Batteries lol

[rszgeyb]

@quadlawnguy, all my ntm motors have blue epoxi balanced

[skogpekka]

I had 3 out of 4 NTM 28-size 1000Kv with shot bearings and poor balancing...
-I find that rather odd, considering the care taken under production as shown here. :/
I might try my luck on a new set though, could have been a poor batch.
