What company makes HobbyKing outrunner motors?

Specifically the 63mm sk3 series... (59mm actual can diameter)

I need to have them add hall effect sensors to the motor's. It is way to labor intensive to add sensors to lots of motors, like a few hundred. I have done around 10 so far, and it just takes forever!!

I guess everyone is interested in this. Mainly because hobbyking sells them like 5x more expensive.

I'd suggest talking to Marco or Hal (Greyborg), as I have a feeling they have connections to the manufacturer, at least for the 80 100 motors. The "7kW" Colossus motor is a custom wound and finished Turnigy 80 100, from the look of it, it certainly shares some of the same dimensions and probably motor core.

So no one knows...??

 

[Dauntless]

This surprises you? I could almost see the factory itself not knowing the motor was one of theirs.

Google says here....

your best bet for contact through alibaba:

Million power group limited prolly contracts several factories to complete their catolog.

I think you will find that there are about 10 manufacturers in China, but they are likely all resellers. I would contact a few on alibaba. Here's one guys email:
eric@xingyaohua.com. He says he's the manufacturer, but I doubt that. He might be able to get you in touch with someone that is.

the company behind Hobbyking is hextronik.com.

You can contact them for order above 2000$ or for custom work (always above 2000$ of value).
They don't accept order lower than that value.

Just out of curiosity, are you putting Hall sensors on these motors for use as servos, or for improved starting from zero rpm, or for some other reason?

I'm adding them to have the ability to start smoothly, and while rolling backwards. Sensorless just fails at both those requirements.

I have seen (by chance) your comments about: "What company makes HobbyKing outrunner motors? -Specifically the SK3 series" ...

see: http://www.rcuniverse.com/forum/m_11426913/tm.htm

IT IS THE COMPANY CALLED: SUNRAY TECHNOLOGY, IN CHINA -that manufactures these motors.

They also make: Hacker motors, Z-series Hyperion motors, and some other well known motor brands.

The Turnigy SK3 motors are very similar, in many respects, to Hacker and Hyperion-Z motors.

Also see: http://www.rcuniverse.com/forum/m_11428138/tm.htm

Hope this helps, Dr Motor

Following the various forum threads, there seemed to be no real link to this company, apart from some spec shets claiming to be from the company, from new members on the forums. Which could just be some company that makes very similar motors.

How do you know this company is the actual manufacturer for the other brands, apart from comparing spec sheets?

I sent them an inquiry for custom motor, but no response yet.

Hello Adrian, the website for the SunRay Technology company is: http://sunraytechnology.com
1. There is no information at all, about what they make on their website, as they are an OEM company, and they seem to prefer to operate with some secrecy.
2. I am sure that Hacker, Torque and Hyperion companies etc do not really want people to know that their motors are manufactured at this particular factory. -They prefer to keep their "trade secrets".
3. The "spec sheets" that you mentioned, actually all came from me -indeed, they were sent to me directly by the SunRay Technology factory.
4. I can tell you that without any doubt, this SunRay factory makes Hacker, Torque, and Z-series Hyperion outrunner motors.
They also make: Pelikan Foxy, LiPolice, Shulman Aviation Fury, OK Hobby Infinite, Gens Ace, Viper VA, Apache, Nova-Line, outrunner motors.
and of course also: Turnigy SK3 motors.
5. Several "industry experts" and people "in the know" have confirmed this to me.
6. The fact that: Hacker, Torque, and Z-Hyperion motors (and OK Hobby Infinite motors) were all made in the same factory, has actually been known for a few years at least; judging by some comments that people have made on various forums.

Hope this helps. Good luck to circuit with hearing from them; they sell in large numbers, rather than one-off motors, seems to me ...

Here are links to the various motor "spec sheets" that were posted. -This information came directly from the SunRay Technology factory. It shows at least some of ther outrunner motors that they produce.

Still not sure how can you "tell without any doubt".

Motors you have referred to as identical in the thread you linked to, in fact have obvious different external geometry, even if basic spec sheet specs are similar. Which only proves that the stator size, windings, and magnet strengths are similar. But doesn't really confirm they are identical in all important respects.

So what is the proof?

Sorry I am just a bit skeptical of new forum members claims. When it appears to promote a single company.

Hello Adrian: Thanks for comments. No need to apologise.
1. I only joined this forum, to respond in this particular thread. That is why I am a new member here.
I have been a member of RCGroups, RCUniverse, WattFlyer, for at least 9 years ... My main interest is planes and helicopters.

2. I have no interest in "promoting" SunRay Technology. I just noticed that the specs of some brand motors were identical, like Hacker, Z-Hyperion, OK Hobby Infinite, and took it from there ... -The final answers were quite dramatic, involving far more motor brands than I realised.

3. It actually took 2 or 3 years, of digging a little bit here and there, to find that the company that made these motors was actually SunRay Technology.

4. The fact that some of the motors have different external cases and colours is of little importance. The outside appearance of the motor, and the particular shape of the end housings, is just cosmetic. It has no effect on motor performance. see: http://www.rcgroups.com/forums/showpost.php?p=21396796&postcount=206

5. Allow me to say: It does not matter to me, if people accept this account or not. The objective evidence all seems to fit well with this account. It all seems to make sense. And it has been quite fascinating, to slowly discover these bits of the story, over 2 or 3 years.

Sent them a reminder (second email) and got a response from Hacker (my emails were forwarded). They do have some promising products coming up soon. But no car-capable motors, unfortunately.

I also got no response to the email I sent...

Have you tried GSModels?

Can you please give me some insight on how to hook up hall sensors to the Sk3 motors? or a link to a thread about it?and a hookup guide for a complete newbie
Thanks a heap!
