I am controlling a stepper motor (M42SP-5P) with BUZ11 MOSFETs. The winding resistances are \$22\Omega\$ and each winding is 18 mH as I measured. I am driving it with 24V, so let's say the drive ...
The 500W inductive load question got me thinking. Cars have large radiator fans that often draw more than 15A and are pretty inductive. Do automotive relays have any sort of protection from ...
