Hi,

I'm new to your forum. My application is not a CNC machine (its actually a robotic arm), but you guys seems to be the stepper motor experts.

Our application needs a DC Motor (can be stepper or servo - does not matter to me). The output side needs to deliver at least 50Nm (preferably closer to 95Nm) at a maximum of 90rpm.

I typed these numbers into the calculator on the link provided (Stepper Motors), it just said - out of stepper range, look into servos.

Can a gear box be added? My reasoning is that with a 25:1 gearbox, I only need 4nM of torque since at the motor end I'll then get 4nM x 25 = 100nM) At 4nM the calculator suggested that "my system could be supported by a: Linistepper".

I also don't have a clue where to buy this locally - I just get Chinese suppliers when I google it.

Some guidance will be much appreciated.

Thanks in advance.

Ollie.

If you can get shipping to S.A. there is a whole lot of Bayside Planetary G.B. on ebay.

Thanks for your reply. Please excuse my ignorance - how do I know the gearbox will work on the stepper? Are they all standard to fit?

With Bayside, the input side usually conforms to the NEMA mounting and shaft dimensions.
