Hi,

Yes you can parallel up L298's even if current chopping is used. A pair of L298's is good for about 3.5A/phase.

You can use one L298 per winding as per Fig. 7 or just connect every pin on...

You should be able to go faster than this but you will have to provide an acceleration ramp rather than clocking at a fixed rate which is what I assume you are doing?

You should use twisted triples with a 6-wire motor. One of the wires will have zero current making it in effect a twisted pair.

We usually incorporate a power save feature into our stepper drives to make the motors run cool. We reduce the current to a percentage of the full current. If you don't need a high hold torque at...

Hi Alan,

I think there is more to these dampers than just an attached mass. An additional mass would only change the system inertia and lower the primary resonance frequency. This may or may not...

Hi Eric,

This will only work if the motor does not have a hardened shaft, very often motors do.

Hi,

I have made simple vibration dampers for small size 42 stepper motors.

An annular steel ring is connected to the 5mm shaft of the motor by a small piece of neoprene rubber tubing 5mm ID,...
