High torque servo motor for heavy duty leather sewing machine

Also.. pretty deceiving in the advertisement Vid. . I would have liked to see it punching thew some material that they actually could brag about with using that 750 watt servo drive . That stack of Poly Webbing is Not high density weave like they say . It actually really loose weave strap webbing, and super easy to punch .
.

1ply webbing is easy easy to punch,but not easy to stitch 30mm thick webbing.....We tested with 15mm vegetable tanned leather, but will show in next video

Looks kinda' like the brushless motors I've already had on a couple machines, for a couple years, now...............Yawn......

But no good quality brushless motor for heavy duty industrial sewing machine.....

will this motor available though your German suppliers too.

If not feel free to send me one for testing

HM-750T Super powerful, quiet and reliable servo motor for extra heavy duty leather sewing machine (Energy saving servo motor, easily control the speed)

How many coils does this motor have?

Excellent question directly related to the torque claim.

The reason I asked is that the Sailrite Workhorse ($225 US) and the Reliable SewQuiet ($199 US) even though they are only 550 watts are 12 coil construction versus the typical 6 and 9 coils of lesser cost brushless motors. As a side note a inexpensive and maybe questionable quality Chinese 12 coil 750 watt off aliexpress is about $190 US. My thought is the more coils should help provide a smoother low speed torque range.

Does the Amperage draw, have a play in the low end torque ?  I would think it does.  how many Amp's does this drive use ? . I know the Servo Drives don't use but small amount of Amp draw to run . it varies ( like about 3 to 6 amp ) depending on the make/models Spec's .

The first stitch will need about 160 amp

 other motor listed at 800 watt is false.   The Kinedyne motor is a true 750W motor, much more powerful than other manufacturers 800 watt motors. See how it stitch 15mm stiff leather,

9 coils

The motor and arm linkage look pretty generic, the major difference that I can see is their control unit has more buttons on the front, which presumably means not having to access the menu to make basic changes (like speed control). Other than that my guess is it won't be much different to most of the other 750w servos out there.

You can see the difference in  this video,

A couple of important points from the video

- the sound level doesn't increase when you turn on the motor. Of course it doesn't because the motor isn't running! It only runs when you feed electricity to it.

- it uses less power at idle than a clutch motor. Of course it does, see above answer. A clutch motor runs continuously once switched on, a servo doesn't.

It may very well be a nice motor, and I like that the speed can be varied without having to delve into the menus, but this sort of advertising does you no favours.

What?  You must be a decimal off.  No way that tiny motor draws 160 amps at 110 volts.
