Tiivistelmä
With the increasing demand of using electric power and unpleasant of using brush motor; the usage of Three-phase Brushless Motor has been significantly developed in industry. However, with market-standard motor driver, there are many inconveniences for small institutions or companies in either application developments or education purposes. For instance, the size and the price of driver. Therefore, the object of this thesis was design modular sections (Software program, PCB driver and PCB connectors) to drive a brushless DC motor. The entire works are divided into four steps. 1) Pre-study, is for designing a circuit schematic and according to that to select the relevant components. 2) PCB design is for the hardware driver PCB design. This makes a flexible for size of hardware driver board. 3) Software programming, in this case, is based on M16C62P microcontroller in embedded C programming. The software control could also be done by FPGA or other types of microcontrollers as long as the minimum requirements are fulfilled. This makes a software control function flexible. 4) System testing tests system functionality and stability as well as PCB board and Software programming functionalities. With all work, the motor could finally be driven by microcontroller and hardware drivers with high level currents. The various possibilities can also be chosen to drive the Three-phase Brushless DC Motor with users demand and cheap price.
