Dear all,
I am proposing to use pwm control for a hybrid stepper motor application i am working on. My primary concern is with the soft iron teeth in hybrid designs struggling with the high frequencies. As they are only teeth i feel eddys are likely manageable and would hope the norm are laminated teeth but am not trusting the manufacturers replies.
Anybody done this before in microstepping and can confirm whether it is really that big a concern? All the app notes i can find imply pwm control is fine but none specifically say but do speak of both hybrid and reluctance steppers alongside pwm so it would seem there is little concern. Hybrid stepper manufacturers also imply standard stepper drivers as suitable and most of those are pwm now a days.
Thanks in advance
