is anybody tried this brand and quality stepper motors/drivers kit

[Nilesh]

hello,
i found something on Ebay. which looks heavy duty for my usage
more over in future i want to transfer this kit to conventional milling machine
for more metal works.

4 Axis Nema 34 stepper motor 1232 oz.in 4leads,5.6A &Driver CNC KIT | eBay

is anyone used this brand and quality " Longs motor"
i am also thinking on " Automation Technology inc"

Thanks in advance ...help appriciated

I'm using the longs stepper drives and they work great, motors noise is virtually nonexistant.

When using stepper motors, for best performance, the motors, drives, and power supply must be matched along with the drive system.
In most cases those motors are 2-3x larger than needed. When using large motors not properly matched to the system, performance is usually far less than expected. IN most cases, motors 1/3 the size of those will outperform them.

Do some research and make sure you know what you're buying before you spend your money. I've seen several people buy similar kits, only to replace them with smaller motors that offer much better performance.

hi,
thanks for help and advice,
their driver board are enough capable work high amprage/load
bcoz right now my plan is to use this with DIY router but in future my plan is i want to transfer kit it on conventional milling which is heavy compare to Router,
more over i am planning to use squre machine thread screw
so i am choosing this sort of heavy duty motor.

my steper motor knowledge is limited i am paying attention on torque/OZ value... so i guess this is 1236OZ means enough for my projects.

can you please tell me am i thinking right side ??

help appriciated...thanks in advance

thanks a lot for advice..
currently i am doing same thing before i buy...
more over i want to know .. stepper moter with encoder give very precision position control ? is it correct ..i don't know much but thninkg on that design too.

thanks again

FWIW: A higher voltage power supply would be better suited for those steppers. The phase inductance is 5.5 mH. The higher the inductance, the less work will be done for a given voltage. If you want the best performance out of the steppers you will need into use a higher voltage. I would recommend going with a 55VDC to 60VDC PS. Unfortunately, SMPS with voltages above 48 VDC are hard to come by since there are few manufacturers producing them.

thanks for help me to understand about PSU...much much appriciated
