The cheapest of the cheap servo motor

[NovaScotia]

Hello again Zac, I've just seen the REX servo above listed on Amazon.com.au for $195 AU.  With exchange and delivery from the US, I paid $203Can for mine.

$280 delivered - and it comes from the US! Not bad, I guess, but I'm happy with my $99 one, does the job and I'm $180 richer.

As a new member I would to add a note about servo motors.  After realizing that my Chinese shoe patch would not sew well enough to sew the holsters I make I decided to make it an automatic awl machine.  So I got a servo motor from Amazon.  750w I hp. $125.   Digital  control.  Mounted it on my shoe patch table and replaced the 4 inch pulley with a 1 1/2 inch pulley driving a 10 inch pulley  on the shoe patch machine.  Set the motor to the slowest spi and all works fine. very slow and plenty of power.   For a similar motor on Amazon see Mophorn.      Now since I read some of the post about sewing machines and people were having trouble finding belts the right size.  Actually  you can make your own belt by cutting one that is too long and using  industrial adhesive to glue the sharp angle cut and also wiring or sewing the joint together.  Please note: this will not work on your power mower.  

If this info. is in the wrong place. Would someone please let me know where to put it.

Back in the early days of cyanoacrylate adhesives the ads for them usually showed them being used to glue the two ends of a cut rubber composite drive belt together, and then the belt being stressed..because that is one of the things that they work best upon. :)

I sill use leather belts on some (most) of my machines and if it's a short belt I sew them with heavy thread.

Yep, rubber and skin, super glue works exceptionally well on them.

Thanks everyone I am going to give the $99 servo a go. Hopefully it does the job, I will let you know how it turns out.

On the pricing between Aus and the US, there is obviously larger quantities meaning less cost but i think there is a lot of people also know they can get away with charging higher prices in Australia. At my previous job was working for a larger Australian company which sold here and also and in America and the acceptable profit margins in America was much less than what they expected here. The reasoning being that America was more competitive. The internet and online shopping is definitely making it harder for companies to do this so hopefully it will improve over time!

I haven't enjoyed the brushless style servo very much.  They can be a little jumpy when first starting out.  Beyond that I really dislike the two button system to adjust speed and other features.  I much prefer the simple variable speed servos with a dial to set the max speed.  They are quite inexpensive in the states.  Not sure what the availability and shipping is in Australia.   

I swap the pulley for an extra small 45mm pulley, and they work great.  

Good luck with it.  

Hi Pinto, do you know If your motor is slower than 500 R.P.M  ???  Do you know how slow can work your motor???

Would like to know wether your servomotor type is slower than the brushless chinese servomotors...¿¿???

I can find this kind of motor in UK , I am Actually buying servos, in Spain, that goes to 500 R.P.M. I need to add a reducer pulley system for go slower.

Hope your kind of servo save me to use the pulley system.

Hi Miguel,

I usually don't go by the numbers on the dial.  If you turn the variable speed knob down too far, you'll lose all power.  

I usually set the dial to 1200-1500 max speed.  It seems to start at 0 rpm, and ramp up in a slow and predictable way.

If you need crawling slow, stitch by stitch, then you'll need to add a speed reducer.

Hi Pinto, thanks for your reply. So, you think that your motor can go slower than 500 R.P.M ??? Maybe the slower is around 200??? Or even less than 200???
