Abstract
The purpose of a digital direct current (DC) motor control is to use a digital signal representing the demanded average voltage supply to DC motor. Operating and driving speed concept of a DC motor need to be study. Therefore, this project has to take a part to design and develop a computer-based DC motor speed drive interface card system. The project has divided to two parts which are DC motor drive circuit design and Personal Computer (PC) to microprocessor serial communication interface. On the first part, PIC 16F873 microcontroller and A3953SB Integrated Circuit (IC) Full-Bridge driver motor is used. PIC 16F873 microcontroller is used to generate Pulse Width Modulation (PWM) signal. The PWM signal is important in order to use the A3953SB Full-Bridge driver for driving the DC motor. PWM signal is calculated by determine the frequency limit and duty cycle limit. The frequency limit is about 29100kHzfkHz≤≤ and duty cycle limit is about10%. Then, the PIC 16F873 microcontroller is interfaced using coding which is developed using Programmable BASIC language. The A3953SB Full-Bridge driver has 4 main pins which are ENABLE, MODE, PHASE, and BRAKE pins. These 4 pins need to be connected to PIC 16F873 microcontroller in order to drive and control the speed of the DC motor. On the PC interfacing part, the system is interfaced to the PC using serial cable (DB9). The platform software, MPLAB is used to communicate with the interface card system. This software acts like HyperTerminal for data communication. As a conclusion, the expected result of this project is the speed of a DC motor can be control and communicate serially to the PC for computer-based control purpose. 90%D≤≤
