Sizing: Load to rotor inertia matching
We’re continuing our discussion about stepper motor ringing and inertia matching. We had established the following load-to-rotor inertia ratios: Figure 1: Inertia Matching in stepper Motors 1:1 load-to-rotor inertia as an ideal ratio. Greater than 1:1 …
Sizing: Ringing and inertia mismatch
I’m sorry if you Googled “ringing” because of a hearing issue and end up on this blog. You should Google “tinnitus” instead or search the WebMD site. Now where were we? Oh yea, in our last posting we were talking about load-to-rotor inertia matching. W …
Sizing: Load to rotor inertia matching ratios
We started our stepper motor sizing discussion with the last posting and introduced the NEMA rating for motors. The stepper sizes that we talked about ranged from the smallest NEMA 14 up to the largest the NEMA 34. Other manufacturers might have smalle …
Sizing: stepper motor physical size
Our last posting talked about applications that had marginal torque and that caused our “Hybrid” motor to correct its position. These applications were essential “path critical” and the correcting moves the “Hybrid” control did cause the path or the mo …
hMTechnology and Position Make-up II
In our last posting we raised some questions about how the “position make up” made up for the steps that were removed. Position make-up will compensate for position errors due to a disturbance during a move by reinserting missed steps into a motion pro …
hMTechnology and Position Make-up
Our last few postings talked about the “torque mode” operational theory that we added to our “Hybrid” drive. Prior to that we added “variable current mode” and “position makeup” If you haven’t read about those drive enhancements, I suggest that you go …
Industrial Connectivity and IEC61076-2-101: M12 Liberty MDrive Introduced
Since the early 1990s, the Fieldbus protocols have become the preferred industrial network system for distributed control. Machines designed around these standardized networks have evolved to become more robust and environmentally resilient to meet dem …

Four Quadrant Drives: Torque Mode with Hybrid Drives Part II
In our last posting we discussed how we made our “Hybrid Drive” act like a torque motor. One issue that you do have be aware of is the fact that at some point in the stepper’s speed-torque curve the torque is going to begin to fall off as a function of …

Four Quadrant Drives: Torque Mode with Hybrid Drives
In our last posting we discussed an application where we used our “Hybrid” drive in the “Torque Mode” to apply tension to a web.And we asked how does the “Hybrid” drive know what speed to operate at when the web velocity changes? It’s looking at its ow …
