Abstract

The article is concerned with the engine combined design of the electric separator consisting of an electric motor stator and solid rotor that performs the function of the working body of the electric separator drum. An electric drive is an electromechanical system consisting, in general, of interacting electric power converters, electromechanical and mechanical converters, control and information devices. The electric drive of the separator with the motor of the combined design contains the control device and the motor of the combined design. The article presents a mathematical model of the engine combined design of the electric separator based on differential equations describing electromagnetic and Electromechanical processes in the engine combined design of the drive cage, making it possible to obtain a functional relationship between dynamic characteristics and parameters developed by the engine combined design of the electric separator. The article considers the derivation of the expressions of the moment of resistance and the moment of inertia of the electric drive of the separator, which is an integral part of the combined design motor. In the expression of the resistance moment and the moment of inertia of the electric separator combined with the engine design variables are introduced taking into account the geometric features of the mobile elements of the combined design engine of the electric separator and changes in the composition of the multiphase separated piece of the product. The mathematical model is implemented in the software package MatLab Simulink and makes it possible to consider the influence of the parameters of voltage (the supply voltage and frequency supply voltage, the degree of distortion of the sinusoidal waveform of the supply voltage, the highest voltage harmonics, for example, the fifth or seventh); change the torque and moment of inertia generated by the separated piece product, the electromagnetic torque of the motor combined design of the drive cage and the speed of rotation of the working body of the electric separator combined with the engine design.
