This master’s thesis discusses the design and testing of an integrated drive for a brushless AC motor. The motor controller is based on the MCF8329A integrated module, which includes all the key functional units required for sensorless control of a brushless motor.
In the introductory part, we briefly present different types of brushless motors, their characteristics, and typical applications. We also define the requirements that the developed drive must meet. Furthermore, we present and describe the most common motor control algorithms and compare them.
The core of the thesis is dedicated to the design of the device, broken down into functional blocks, and a detailed explanation of the printed circuit board components. During initial testing, we encountered certain issues, which are described and successfully resolved.
In the conclusion, we present the results of various measurements and tests that were used to systematically evaluate the drive’s functionality, reliability, and compliance with technical requirements. Based on the analysis of the results, we assess whether the drive meets the defined design goals.
