Time Delay on Loss of Power
Time Delay on Loss of Power
(OP)
I am currently working on a project were I have a primary and secondary brake and the secondary brake needs to have a 1-3 second time delay after the 1st break sets. For this application we need to use two electromechanical brakes and the brakes selected use a solenoid. My thought was to place a capacity parallel to the brake solenoid sized based on the drop out voltage and resistance of the solenoid similar to the attached drawing. My questions are am I missing anything and would this also work with an actuator brake. Thanks.

Do the solenoids hold the brakes off, or apply them?

A capacitor is probably the only electrical method of holding off the brakes for that length of time. How much current do the solenoids draw?
