I'm about to buy a stepper kit from http://kelinginc.net but have some issues deciding on witch motors to get. The motors will be used for a fixed gantry design and be driven by a g540.
For the Z-axis I'm thinking one :KL23H284-35-4B but for the fixed x and y I'm undecided.
Trying to keep to NEMA 23 sized motors I'm looking for the type with the most torque once they go up in speed a bit. Naturally I thought bipolar parallel but the biggest at kelinginc.net are hybrids. I get the hunch that hybrids are not as good when it comes to torque at higher speeds as true(?) bipolars.
F.x. the KL23H2100-50-4B is 570 oz-in has four leads and I see no torque curve.
The KL23H286-20-8B is 425 oz-in but has eight leads and still no torque curve. Seems like this one is the strongest with eight leads?
So will the possibility to run the later in parallel result in higher torque once you go up in RPM?
