Hi Group,
I have a case were my fuse is just above the stall current of a locked rotor.
I also know that as the locked motor heats up the resistance increase so the
current will start going down.
I have seen a case where if the motor was lightly loaded and it was quickly
stalled, it would blow this fuse. I have an free wheeling diode across the
terminals.
Is there any case where a lightly loaded motor which is more inductive could
discharge a large about of current back down the AC line in it was suddently
stalled, causing a fuse to blow? The Model the inductance as 0.5 henry and
resistance as 20 ohm. The voltage is120V AC full-wave recified.
Any suggestions?
Paul
