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 On 8/26/2022 at 6:48 PM, trash treasure said: 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..... Quote

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. kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver

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 . . Quote

The Kinedyne motor is a true 750W motor, much more powerful than other manufacturers 800 watt motors.

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, Quote
Members dikman Posted October 6, 2022 Members Report Posted October 6, 2022 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.
