Development of best servo motor for leather sewing machine

[dikman]

A google search for Kinedyne was interesting, the company specialises in manufacturing cargo handling/securing products. They do not make motors they source them from Hightex, who I believe manufacture Cowboy sewing machines. So, who is Cowboy Outlaw working for? The posting makes it sound like Kinedyne, but that can't be the case because they don't manufacture motors but the OP is talking about seeking information for the next motor they're making.  If it's Hightex then I doubt they would be very interested in what we say because by his own admission they make motors for large manufacturers who want features we don't. 

And you didn't answer my question - does it have a built-in gearbox, which you said it does in reply to GerryR?

This is becoming confusing.

I wouldn't get too wrapped up about price. Lots of people splurge on expensive stuff for their hobbies. Lots of people here drop thousands on a machine anyway, what's a couple hundred more for a cool motor? And bragging rights?

I've never found easy availability of the HM-750 in the couple of years I've known about it. I don't even know what they retail for, so will we even be able to point and click the new wonder motor you guys are designing?

Al, I understand what you're saying, I've spent $1000's since getting into shooting (primers and powder are ridiculously expensive now ) and once I got interested in leatherworking I sort of lost track of the expenditure BUT I also do my homework and there's nothing I've read to indicate replacing my existing motor/reducer setup with this "supermotor" is economically viable, nor do I think it will do anything better. Goods in Australia are more expensive than in the US so unfortunately I tend to get "wrapped up" in pricing (particularly since that Chinese Cough has stuffed up shipping costs!).

I'm just genuinely confused about this motor and this thread, I think Cumberland Highpower probably picked it, the motor is already made, with the features in the first post, and this is essentially a publicity blitz.

I totally agree. However, it is a good discussion about what is used / needed by the average leather hobbyist or small commercial user which is often completely different then what would be needed in a large manufacturing environment.

My opinion is the hobbyist sews for pleasure while the commercial user sews for profit. 

I am still a bit confused about whether this new motor has a build in gear reduction which would be just another take on what Landis had done back in 1998 by putting a 52 to 1 helper geared motor on the Singer 29-71 patcher. I figure if they were doing it today they would have used a brushless servo motor with a gear box attached. I did a video of the one I owned and the geared helper motor can be seen at 4:18 in the video ( https://odysee.com/@SingerSewing:0/singer:a  ).

That was my point Gerry, I don't think the OP understood what he was agreeing to so no, no gearbox. A bit more searching confirms that Kinedyne is a brand of Hightex, so these are merely Hightex 12-coil servos, not something radically different and super-special. This merely confirms that it's a publicity exercise as anyone who thinks a company like Hightex is going to take notice of discussions about their motors on a forum and make changes to suit their wants is kidding themselves. The OP said it himself (herself?) they are made for the wider commercial market.

Well, according to the way the OP responded to my post above, he claimed he achieved all the points I mentioned, which included a 5:1 gear reducer.  Must be the language barrier, as I mentioned possibly using an AC servo control, and I doubt he has done that.

I´m pretty sure there is a market depending on the price and the features of this motor. So asking potential customers for their needs is a good thing in general. Maybe there will be a line of motors with different features and therefore different prices. The range of leather workers is wide. Some have a deeper wallet than others and some have tools for installing motors and DIY building speed reducers that others don´t have (f.i. due to income or the space they have). So a slow start high torque and affordable plug and play motor is not a bad idea I think. Let them do their research and work at the end we will se what they are coming up with and we can decide if we need it or not.

My 2 cents.

Exactly. And people will spend long money for the latest and greatest. Thousand dollar cell phones when a $40 phone does the same thing, handgun optics that cost more than the handgun they're attached to, the list goes on.

I believe what OP was saying is that they already have a 50 RPM start speed, so no need for a 5:1 gear reduction. I also think there's a language barrier involved. I don't know any more than the rest of you how sincere he is, but it's a worthwhile discussion. Definitely got me rethinking some of my choices. Wiz's comments above have made me wish I hand't turned my nose up at those outdated brushed servos!

EDIT: Let's not forget leather stamps. Look how many people buy $50 big name stamps when a $7 Hobby Lobby stamp is pretty close.

Yep, me too. I got all excited about all the features on my new wiz-bang first servo and Wiz's comments on analog/brush servos with only a speed control knob had me thinking he needs to move with the times. It's only as I've gained more experience that I've realiised he was right all along. If I could get hold of one of those it would be no big deal to modify it to move the knob away from the motor and near the head unit. That would be an ideal setup.

Meanwhile I'll stick with my el-cheapo servos and home-made speed reducers as the Kinedyne motor is not going to do anything better, in fact I suspect my setup is better for my needs as I will get more low-end torque with the reducer. Plus it gives me the ability to tweak the operation by changing the pulley sizes to give me even slower speeds with even more torque if needed.

Our motor do not use buit-in gear box. No need of it
