Abstract
Electric motors play an important role as the primary power for conveyor and drop lifts in manufacturing systems especially in automobile manufacturing factories.Many electric motors equipped with brake systems have sensors that determine where they should stop. This brake system needs to be maintained to keep proper brake gap consistent. Measuring the brake gap of electric motors is one of the main jobs of maintenance department, but this is a difficult task because most of the motors are located in unsafe spaces, like the upper end or under the lift pit. This paper proposes a new approach to measure the brake gap of motors to reducemaintenance risks, thus saving costs. The method suggests using vibration acceleration to measure the motor gap in running production system based on mechanical model.The effectiveness of this research is indicative by experience results.
