Motor Current Signature Analysis (MCA) is a predictive maintenance method that analyses the electrical content of motors to help determine mechanical and electrical problems. Changes in the flow of current can be used to identify faults related to rotor bar defects, bearing failures, misalignments, and air gaps by technicians. The ability to be performed without equipment shutdown is one of the biggest benefits of MCSA, and this aspect makes it suitable for those processes that operate continuously. The method offers insight even without invasive inspections, which in the end increases motor life and decreases downtime.
