  • Patent number: 8330407
    Abstract: An electronic protection system for motors is provided that includes electric current (SC1-n) sensor elements, more specifically Hall positioning sensors, and electronic circuits for electric tension reading. The signals are processed by a central processor (2) that executes a set of rules (A, B, C) and makes inferences based on the collected data in order to protect the motor (M, M?) against possible failure. Furthermore, a method to protect motors (M, M?) is provided, based on a set of rules (A, B, C) in order to characterize failures and trends of possible failures, so that the motor does not operate out of its specification for the system to deactivate it.
