Mechanical learning device and method for adaptive learning of the expected service life of a power device as well as service life - forecasting device and the motor drive direction comprising the mechanical learning device

摘要

Mechanical learning device (1), which the expected service life of a power device of a motor drive mechanism against the direction (1000) for converting direct current into an alternating current by means of a switching process of the power device for supplying the alternating current motor learns with alternating current, whereby the mechanical learning device comprises:a state, a monitoring unit (11), said one of data with respect to the number of switching operations of the power device, data with respect to the boundary layer temperature of the power device and data in relation to the presence or absence of a failure of the power device existing state variable is observed; anda training unit (12, 15), which the expected service life of the power device according to one of the state variable defined training dataset learns.
