Abstract
A method for monitoring the health of a brake plate having a solenoid with a solenoid air gap includes creating a reference solenoid current profile for the brake plate solenoid air gap, by: calculating a nominal solenoid current profile based on the air gap under nominal conditions, calculating a upper and lower limit of the nominal solenoid current profile, based on an impact of at least one external variation and/or tolerance of the brake plate, and creating the reference solenoid current profile by combining said upper and lower limits into the nominal solenoid current profile. The method also includes generating and measuring a solenoid current curve of the brake plate and determining if said generated curve of the brake plate is between said upper and lower limits to determine that the brake plate is healthy.
