  • Method for monitoring a blocking member, and electromechanical actuator
    Patent number: 9574633
    Abstract: A method for monitoring a blocking member (12) of an electromechanical actuator (1). The monitoring method comprising the steps of: determining a value representative of a power supply current of a motor (11) during an off-load operating phase of the electromechanical actuator (1); comparing the value representative of the power supply current with a predetermined current threshold defined from nominal off-load operating characteristics of the electromechanical actuator (1); and detecting an accidental locking of the blocking member (12) when the value representative of the power supply current is above or equal to the predetermined current threshold. There also is an electromechanical actuator (1) comprising a blocking member (12) monitored by such a method.
