Návrh a realizace frekvenčního měniče pro malý třífázový motor.

Abstract

This thesis focuses on realization of the prototype frequency inverter and partly on the problem caused by the supply of asynchronous motors.

In the first part of the thesis analyzed basic information on asynchronous motors, frequency converters and inverters for subsequent selection.

In the second part, the design of individual components, such as the power and control part of the inverter, as well as the design of supporting elements such as power supply and cooling selection are carried out.

The third part of the thesis is the realization of proposals in the program KiCad EDA and 3D models of individual parts are also created.

In the fourth part 3D visualization of mechanical construction is created using SolidWorks software, which is subsequently realized.

The fifth part is to verify the function of the proposed inverter with basic measurements.
