and all other motor as receivers, therefore the speed set in the transmitter side of the motor, the same speed will be applied to all the receivers side of the motors [3]. This operation can be possible by using universal asynchronous receiver transmitter (UART) device. Generally the loads applied on the motors is variable, due to that the speed of the motor will affect and satisfactory operation will not achieve. For minimizing that problems, the speed control is necessary. PWM technique is used for controlling the speed of the motors [9]. For PWM generation PIC18F4520 is used. In this method, the regulation of motor’s speed is achieved by changing the voltage of the motor which is adjusted by the duty cycle of PWM. Instead of using transformer and rectifier for giving supply, we used Adapter to give 12V supply to the DC motor. IC7805 is used to convert 12V into 5V supply. 12V DC motor is used for speed control and synchronization purpose. Driver circuit consists of BJT, MOSFET for interfacing between DC motor and PIC, because direct dc motor can’t connect to the PIC. Manpower and time is saved in this arrangement. Satisfactory operation will obtain
Abstract— The main objective of the project is to control the speed and synchronization of DC motors using wireless module with higher efficiency and less maintenance. The speed control and synchronization of motors is an essential part of any industries, therefore it is an at most need to solve this problem. Multiple motors are working on load in an industry with one motor act as master and remaining two motor acting as slave, so synchronization becomes necessary. In this paper, the DC motors are used for synchronization because of their smooth operation, less noise & low torque. PWM technique used in our project to control the speed. Synchronization have been done through USART device using wireless module (WIR-1186v2). Keywords—DCmotor,PIC18F4520, PWM technique, Driver circuit, Wireless module, LCD, etc.
1.1 Speed Control And Synchronization
1.INTRODUCTION
a. Initially, the 220v AC supply is fed to the adapter which converts 220 into 12v supply. After this 12v supply is given to the positive terminal of 12v dc motor. By using regulator IC7805, 12V is converted into fixed 5V DC supply and it is given to the PIC18F4520. b. The required speed is entered using a switches (Sw1, Sw2, and Sw3) which is connect with the PIC. Where switch Sw1 is use to START/STOP the motor, switch Sw2 is use to increase the speed of motor and switch Sw3 is use to decrease the speed of the motor. c. The DC motor is interfaced with the PIC through BJT and a MOSFET together forms a driver circuit and drive the motor.
Traditionally conveyor belts, line shaft, pullers are used in order to synchronize multiple motor for doing particular works. But these techniques have many drawbacks such as the master slave [main motor] will be the hardest to start, stop and maintain smooth motion on the whole process. Maintenance is bit difficult as there are more mechanical parts in the system. This can be come over by using the wireless synchronization of multiple motors [1]. This project is designed to overcome all these problems. In this project, wireless technology is used to synchronize the motors without any differential error speed. Among all the motors one motor acts as transmitter © 2017, IRJET
