Embedded Project on Speed Synchronization of Multiple Motors in Industries

By | June 22, 2018

ABSTRACT:

The goal of this project is synchronization of multiple motors utilizing wireless technology. This project utilizes radio frequency to synchronize motor speeds. This is appropriate for numerous industries like textile mills, steel plants, paper plants wherein all motors utilized on the conveyor are desired to be synchronized.

For an example, in textile mills where multiple motor work all the while on a conveyor line to draw clothes, it is essential that all the motor there should keep running at same speed, with the goal that adjusted strain is accomplished to stay away from garments getting harmed.

In this project, motors are wirelessly synchronized to make the differential speed error among multiple motors to zero. One motor goes about as transmitter and all the rest as receivers. Consequently, if a specific speed is set in the transmitter then all other motor speed would be coordinated to a similar speed of the primary engine. The method of correspondence is the radio frequency.

BLDC motors utilized operate based on PWM control. Each motor has a closed loop feedback system giving RPM reference by a shaft mounted IR sensor course of action whose output is sustained to the controller in the circuit. A display unit displays the full speed and one can enter the desired sped range with help of a keypad to acquire the required speed for all the motors.

The pulse width output from the microcontroller would be automatically adjusted to maintain up the DC capacity to the motor with the end goal that the entered speed percentage coordinates the running RPM. The above operation is carried out by utilizing one optoisolator and a MOSFET for driving the BLDC motor duly interfaced from the microcontroller.

In various stages of operation, motor needs to rotate at a different speed, so if the change the speed in transmitting motor at that point rest of the engines are balanced as needs be. The entire operation is made basic by utilizing this technology. Manpower and time are additionally saved in this system.

The future works including giving knowledge to the entire system as if any of the motors senses any fault, the entire system will shut down.
