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

A mechanical learning device 1, which the expected service life of a power device of a motor drive mechanism against the direction of the converting of a direct current in alternation - current through a switching operation of the power device for supplying an alternating current motor with alternating current 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; and a training unit 12, which the expected service life of the power device according to one of the state variables defined training dataset learns.
