DC motor driver design and application using with FPGA based microcomputer architecture

In this study a brushless DC (direct current) motor driver was designed for educational purpose. Controller part of the design was implemented with FPGA based educational purpose microcomputer BZK.SAU.FPGA. Determining the lacks of the BZK.SAU.FPGA in controlling, a communication interface as the form of standard parallel port was designed for controlling peripheral devices. The circuit supplying the necessary electrical power for the motor was designed with the mosfets in the form of three phase bridges. Motor control operations were implemented by writing program code for BZK.SAU.FPGA microcomputer and also, as an alternative, by a hardware controller designed at absolutely logic level. As the result of the study, it was seen that the prepared design can be used as educational purpose and moreover it creates the basis of a microprocessor controlled industrial brushless DC motor driver.
