Need Help!- Nema 23 Strength - N.cm Min in Oz? Not familiar

[guerd87]

Hi everyone,

Im looking to order some motors and drivers through a company I found via the Mechmate website. The company is called Deitech - Driver Motor

They have a large range of motors available but Im not quite sure on the way they are rated. Im looking for a JGRO setup, around 300oz motors (equivalent to the the HobbyCNC ones)

Are any of the motors here around that strength? How do I work it out?

The Driver I am looking at handles 50v, so I would like to get a motor to suit about a 48VDC power supply.

Im also looking at their drivers:

4.2A Max 50VDC - Is this the right driver or should I be looking at another one of their models? They are based off the Leadshine models.

Thanks for all your help,
John

Both have many unit to unit converters.

I found to be a good source for servos, power supplies, controllers, etc. I'm sure there are many others.

I had been playing with steppers for a while before using servos to build our machine. The servos have been very good compared to steppers. A bit more $$ but worth it.
