description: graduation theme qualification work: "Development of an electric drive for a crane with a lifting capacity of 1000 kg". This work is devoted to development of a frequency-controlled electric drive based on an asynchronous motor for a crane with a lifting capacity of up to 1000 kg. Tasks that were solved in the course of the study: 1. Research of lifting mechanisms of cranes, determination of the optimal type of drive. 2. Calculation of the kinematic scheme of the lifting mechanism of the crane, the specified load capacity. 3. Determination of engine requirements and engine selection. 4. Calculation of equivalent circuit parameters to create a model in the Matlab Simulink environment. 5. Development of an electric drive model based on the selected engine. 6. Setting up the drive control system. 7. Analysis of the results of simulation of the drive operation in various modes: Overclocking, Work under load, Braking. In the course of this work, the possibility of using an asynchronous motor powered by a frequency converter in the lifting mechanisms of cranes with a lifting capacity of up to 1000 kg was evaluated. The calculation of the kinematic scheme of the lifting mechanism, the specified load capacity, was made, on the basis of the calculations, the engine was selected. The electrical equivalent circuit of the selected engine is calculated. A mathematical model of a frequency-controlled electric drive has been developed, its adjustment has been made. The analysis of the results of simulation of the drive operation is carried out.
