This work describes the process of modeling an escalator electric drive based on Mathlab in the Simulink environment. General concepts and classification of escalators are given. A comparative analysis of existing escalator models is made. The escalator 4 whose engine power is suitable for the task is selected. Based on the parameters of the escalator, its main loads, the gearbox is calculated and the electric motor is selected and its passport parameters are given, including the passport mechanical characteristics. The parameters of the escalator electric motor replacement scheme are calculated. The definition of frequency regulation is given. The calculation and adjustment of the brake module in the DC link is carried out. The technology of modeling electric motor control systems is studied. A properly functioning model of the escalator electric drive has been developed, including a three-phase AC voltage source, a rectifier, a DC link with a brake module, an inverter, a 160 kW electric motor and an inverter control system. A detailed description of how the model works was also compiled. The tests necessary for debugging the model and searching for possible errors were performed. The results of the model operation are presented in the form of oscillograms of the motor operation.
