Hello All

I have a Electro-Mechanical Brake on a motion stage that is emitting a
lot of noise when it's coil is opened. I understand how a commutating or
snubber diode works, but what criteria must the diode meet? And what
should I consider in designing a circuit to make this coil quiet. It
operates at 24V .46A.=20

I guess it would just have to have a reverse bias brake down voltage
grater than 24V and be able to handle about half an amp of current. Will
the coil have enough internal resistance to dissipate the power or
should I have a resistor in series with the diode? I am very green at
this and unsure of myself so don't thrash me too hard and thanks in
advance.=20

Chuck
