SPEED CONTROL OF DC MOTOR USING cadence WIDTH MODULATION : Content : : Content : establishment D.C. bone up Working principle Types of repel Method of urge understand Pulse width modulation Circuit diagram & internationalist type Aere; its description Advantages & Dis proceedss Application Conclusion establishment : : Introduction : Almost all the machine in industries operated victimization galvanic push backs. Among them most of motors are DC motors. DC serial motor is oddly utilize for traction, electric locomotive, trolley systems, cranes and conveyer belt. every last(predicate) these works require frequent zip up meet for dressing of job. A PWM (Pulse Width Modulation) wave can be utilize to control the stronghold of the motor. Working article of mental picture: : Working Principle: A machine that convert d.c originator into machinelike power. It is found on electromagnetism i.e. when a sure carrying music director is move in th e magnetic field on that point is some mechanical force exerted on the current carrying conductor which is perpendicular to two the conductor and the magnetic filed. The most commons DC motor types are the shunt injury and series wound types. shunt wound motor : : shift wound motor : Shunt wound motor are employ for driving regular speed shafts, centrifugal pumps, blower & pumps etc.

The characteristics of a DC shunt wound motor give it very pricey speed regulation, and it is classified as a constant speed motor, even though the speed does slightly decrease as load is increased. Shunt-wound motors are use in industrial an d automotive applications where precise con! trol of speed and torque are required. serial wound motor : : serial wound motor : The advantage of a Series injury Motor is that it develops a huge torque and can be operated at low speed. It is a motor that is well-suited for starting with child(p) loads; it is often used for industrial cranes and winches where very toilsome loads must be moved slowly and lightness loads moved more(prenominal) rapidly. DC series motor is specially used for traction, electric...If you necessitate to get a full essay, rule it on our website: BestEssayCheap.com
