In the paper, the kinematic structure of the transmission shaft between the driving motor and the working mechanism is studied. The analysis is based on electrical and mechanical similarities. The equivalent circuits, typical for electrical systems, are defined for the transmission shaft concerned. Modelling of the transmission shaft based on a formal analogy between the transmission shaft and the electric transmission line is also proposed. The results of a computer simulation and experimental test are presented. The results confirm the high conformity of the proposed mathematical model with the physical object.

The article proposes the optimization of BLDC motor control by using the load-dependent leading phase with respect to the rotor angular position, which determines the waveform of the sinusoidal voltage supplying the motor. Such strategy results in faster motor’s time responses compared to the motor without control optimization. In addition, by using a sinusoidal voltage source to energize the BLDC motor, the distortions of both the phase currents and the motor torque, visible in the form of ripples, were reduced.
The article presents the optimal configuration of the artificial neural network to estimate the rotational speed of the BLDC motor. The results of computer simulations of an electromechanical system containing a voltage converter, a BLDC motor and an artificial neural network block are presented. The simulation model used was designed in MATLAB/Simulink. The results of computer simulations for three different configurations of the artificial neural network are presented
The paper proposes a strategy for controlling a brushless DC motor excited by permanent magnets. The results of investigations are presented. The investigations were carried out to determine the impact of the proposed control optimization on the dynamics of the drive system during starting the motor and during the steady operation of the system with the motor loaded. The cases of an open-loop system with the use of a voltage reference adjuster and a cascade structure with the use of closed loops for controlling the electromagnetic torque and angular velocity of the motor were considered.
