hi there. anyone with specialised cnc machining services from india. some parts are unproducible locally with local manpower.in other words,my machinists suck....
I have some small servo motors with 500cpr encoders on them. The motor name plate lists 48VDC and 500CPR. The encoders are HP units which run on 5 volts so I...
Using several G210 and G340 without any problem... on a lpt-1 Few months ago i bought 3 G201 's ,till now not used them yet. So wired/connected one this...
Last week I replaced a 212 drive with a 202 on my plasma table. The 202 won't spin up like the 212 and it has a "hammering feel" to it. If I run it at 2000...
The G210 comes with the daughter board set for common signal ground. This is pin 10 on the gecko drive. The g201 requires +5 for signal return to be connected...
... is ... The math looks suspect. The 500 line encoder puts out 2000 pulses per rev. At 4000 RPM that is 8000000 per minute or 133,000 per second. The pulse...
are most servo motors just basicly dc motors... if so can any dc motor be used as a servo moter with encoder. Looking for some good info, and advice for my...
... Servo motors are optimized for low inertia, low torque ripple and low velocity ripple. Will any motor work? Yes pretty much any permanent magnet motor can...
For hobby DIY on a budget steppers are an awful lot cheaper. Whilst I personally don't always like them if your budget is limited I would really look at...
absolutely true. i used 425 oz in steppers on 24 v ,with 1.5 amps. inox screws,no one could stop them at half the rated power.too slow though at 5- 7 rps.what...
I was looking at http://homeshopcnc.com/page4.html For Nema 34 850 oz/in Peak Torque I like to get some opinions on the specs for this unit, I dont have torque...
That motor looks well matched to a Gecko drive. With 2 on the Y axis you should have pretty high acceleration and top speed. I would aim for a rapid speed of...
I think that steppers are much easier to use on a light (such as a router) machine. Servos are always more complicated. Servo's require greater reduction, are...
I am wiring up a gecko 203v system with 900 oz in. steppers and am looking for a good source for flexible 6 conductor 16 or 18 gauge shielded cable. Mike...
im planning on 20 tooth, but was told to use 30 by some member at cnczone to keep closer to 1000rpm... I read someplace to keep inertial low....this unit has a...
... With good sheilding and good grouding practices ie no ground loops and having all cable with shields, noise is not a problem. I have a over 10 years...
... looking ... cable. ... Start Here: <http://www.belden.com/> or here: <http://www.alphawire.com/> Both of these industry leaders have distributor info on...
I user 4 conductor (18 gage) with a foil shield and a drain wire for my stepper motors. I buy mine from Mouser. The wire came from Alpha Wire. Robert Colin...
... Yes, Mouser and Digikey are great sources, especially if you are in an area without any large supply houses. This question got me looking in the Alpha...
Theorectically a servo should be near constant torque throughout it's speed range. However many modern servos, manufacturers have discovered you can push them ...
Whilst it's not ideal the screen is quite wide most tend to use or YY cable, but I see many commercial stepper machines small lathes and plasma cutters just...
The servo inertia looks to be quite low. What pitch is the pinion? You need to work out the pinion pitch circle diameter so you calculate the gear ratio you...
... as per my other post ... im planning on 20 tooth 20 dp(1 inch dia), but was told to use 30(1.5 inch dia) by some members at cnczone to keep closer to...
... looking ... cable. ... You only need to bring back 4 wires to the gecko making your series or parallel connections at the motor. Belden makes a good...
