Speed Control Of Dc Motor Using Thyristor Ppt
For this we are using at89c51 ic and by using this we are setting the speed of motor.
Speed control of dc motor using thyristor ppt. Motor was to generate it with a d c. Until the 1960s the only really satisfactory way of obtaining the variable voltage d c. Supply needed for speed control of an industrial d c. Thyristor can used for control high dc currents and loads.
The controlled thyristor rectifier provides a low impedance adjustable d c voltage for the motor armature thereby providing speed control. 5v dc supply 5. For dc motor control controlled dc power from a constant voltage ac supply is obtained by means of controlled rectifiers or converters employing thyristors and diodes. 220 v 50hz ac supply2.
Connect the gate terminal of the thyristor to the resistor and push button as shown in the circuit diagram. To test the circuit connect the battery and close the switch s1. The firing angle a of t is adjusted by r 1 thereby controlling the motor speed. In this project we are going to show you how to control a load or dc motor using a thyristor.
Place the thyristor on the breadboard and connect the cathode terminal to gnd. Connect one terminal of the dc motor to the anode terminal of thyristor and the other terminal to the switch. You can replace the dc motor with any other dc load and control the any dc circuit.
