@tlfong01 I have decided to measure the torque, however, the motor that I have is quite large so I am implementing a configuration to use a magnetic clutch. placidindustries.com/document-login?h=dfa8e46&src=https://…
@tlfong01 That comes from one of your earlier messages. 1.41 = sqrt(2)

@Amirmkr Yes, your step motor is too large. I usually start testing with current less than 1A, and my max was only 3A (yes, Micky Mouse toy projects).
@Amirmkr Yes, 1.41 = sqrt(2), but I expected you to go deeper, say, it is "peak" value of "rms" I which is chopper bipolar, ...

@Amirmkr I found your comments in "Holding Torque" a bit confusing. I think we need to agree on the definitions of "Holding", "Stalling", "Detention", "Stationary", "Moving", before we move on.
