There are so many accomplished and electrically inclined people here… I have a question. Linux CnC ask for a frequency of driving a stepper motor.
Information on questioned variable to be calculated.
This is my motor.
This is my driver.
I consider the motor to be a power source, resistor and inductor in series. This forums a first order circuit. I then look at the first orders time constant to determine upper limiting driving signal.
time constant= L/R = 3mH/1.4ohm= 0.002143s
The inversion of the time constant is my frequency.
Frequency=1/time constant=1/0.002143s= 466.67Hz
Upper limit of 466.67Hz. Which seems reasonable given the base value in the program. I set the frequency to 300.hz
I have only done the initial calculation. How would you calculate this number?
