I have some basic understanding of MOSFETS. I was wondering if I could use MOSFETS to cycle this motor on/off for an engineering test.
Motor (inductive load)
- 15A continuous current
- 120 A inrush current on start up
I read through a “AN-7517.pdf” which I found at the www.onsemi.com site. They have some good resources. This is attached. I see in the 3rd guiding equation it asks for an inductance. Is the static motor inductance? Is there a way to estimate this or easily measure this?
Couple of questions:
- How do I determine the Gate resistor Value
- Is there a single MOSFET that will do the job, or will I need to put some in parallel?
-How does parallel MOSFETS work if i need to do this?
3)I found this MOSFET - http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/FQP30N06/?qs=FOlmdCx%2bAA3GtR96ES2I6g==
It’s a 60V 32A rated MOSFET. THe data Sheet is attached as well. Would this one work?
Any other general comments/suggestions/advice would be helpful!
