ppt of simulation of four quadrant speed control of bldc motor
ABSTRACT
Brushless DC (BLDC) motor drives are becoming more popular in industrial, traction applications. This makes the control of BLDC motor in all the four quadrants very vital- The motor is operated in four steady state operating modes of torque-speed plane. To control a BLDC machine it is generally required to measure the speed and position of rotor by using the sensor because the inverter phases, acting at any time, must be commutated depending on the rotor position. Simulat ....etc

Four Quadrant Operation
Motor is driving a hoist consisting of a cage with or without load, a rope wound on to a drum to hoist the cage and a balance weight of magnitude greater than that of the empty cage but less than that of the loaded cage.
The arrow in the figure indicates the actual directions of the motor torque, load torque and motion in four quadrants.
The load torque of the hoisting mechanism is of active type and assumed to be constant due to negligible friction and windage for low speed hoist.
Speed torque curve of the hoist is r ....etc

The project is designed to develop a four quadrant control system for a DC motor. The motor is operated in four quadrants i.e. clockwise; counter clock-wise, forward brake and reverse brake. The four quadrant operation of the dc motor is best suited for industries where motors are used and as per requirement as they can rotate in clockwise, counter-clockwise and also apply brakes immediately in both the directions.
In case of a specific operation in industrial environment, the motor needs to be stopped immediately. In such scenario, this pro ....etc

INTRODUCTION
The fully controlled converter can produce a reversible direct output voltage with output current in one direction, and in terms of a conventional voltage/ current diagram(Fig.1:) is said to be capable of operation in two quadrants, the first and fourth. Such a range of operation is useful for certain purposes, examples being the control of a dc torque motor, i.e. a motor used to provide unidirectional torque with reversible rotation (Fig.2), and a DC transmission page link between two AC systems in which power can be transmitted ....etc
