The paper describes the concept of improving the efficiency of the process of diagnostics and monitoring of the technical condition of the electric drive on the basis of brushless direct current (BLDC) motors of robots and vehicles on the basis of analysing diagnostic information of different physical nature, taking into account different types of diagnostic signals formed by individual elements of the drive and measured by electric current and rotor speed sensors. The project realisation provides increase of efficiency of control of technical condition of motors of robots and electric transport, allows to pass from planned maintenance of motors to maintenance on actual condition, to increase safety of movement, and also to introduce systems of automatic monitoring. Functional purpose of the system: monitoring of technical condition of actuator due to the use of digital twin and analysis of signals of mismatch between it and the real actuator. The imitation model of actuator diagnostics is developed.
