The article presents a dynamic model of a drive system of cutting heads of a boom-type roadheader equipped with an inverter system. Such roadheaders are used in underground mining for the mechanised drilling of roadways and for tunnelling in civil engineering. If the created mathematical model takes into account the electromagnetic effects accompanying the work of an asynchronous motor and an adjustable source of the motor power supply (inverter), dynamic effects can be simulated in the drive system working at different, angular velocities of cutting heads with stepless adjustment. The created mathematical model was implemented in Matlab/Simulink environment. The so established simulation model allows to perform numerical investigations, in...
