![]() ![]() ![]() Four Quadrant DC Motor Contr o l without Microcontroller : This project deals with the implementation of four quadrant motor controller using 555 timer along with H-bridge driver.This project also includes the current limiting as well as speed limiting protection circuits. PIC microcontroller is used in this project to control the speed as well as direction of the motor. Four-Quadrant Adjustable Speed Drive for Series Wound DC Motors : In this project, a four quadrant adjustable speed drive is implemented for series wound DC motors which are mainly employed in electrical traction systems.It study about, a coupled heat, flow (CFD) and electromagnetic (EMAG) model of the permanent magnet brushless electric motor with electronic commutation was formulated and then validated A Numerical Analysis of Coupled Electromagnetic and Heat Transfer Phenomena in PM BLDC Electric Motor:This paper focuses on thermal management of electrical motors.When there is any deviation in these two parameters, an SMS is sent using GSM. The present project shows the hardware setup for monitoring the phases and temperature of the motors. Hence it is necessary to protect the motor from single phasing and overheating. Protecting Induction Motor From Phase & Temperature:Over heating of a motor can decrease the life time of the motor, causes insulation failure etc.This information will be sent to the remote PC using Zigbee communication module. Microcontroller compares all these sensor data with respective set limits and accordingly the switches the relay. Various sensors employed in this design continuously monitors the parameters of the motor. ![]() Microcontroller Based Protection for Low Voltage Motors using Zigbee Technology : The main aim of this project is to protect and control low voltage motors from low voltage, ground fault, thermal overload and unbalance conditions. ![]()
