supply was dc‚ dc motors were used extensively to draw power direct from the dc source. The motor speed could be varied by adjusting field current by a rheostat. That was an open loop control. Most of the drives were constant speed and the characteristics could not be matched with a job requirement. A vast development in the dc drives system took place when the ward Leonard Control System was introduced in the 1980s. The system was motor-generator system to deliver power to the drive motor.

Speed Control of Dc Motor Using Fuzzy Logic Technique 1 1‚ 2‚ 3 J. N. Rai‚ 2Mayank Singhal‚ 3MayankNandwani Department of Electrical Engineering‚ Delhi Technological University Abstract:This project uses FUZZY LOGIC TECHNIQUE in estimating speed and controlling it for DC motor. The rotor speed of the dc motor can be made to follow an arbitrarily selected trajectory. The purpose is to achieve accurate trajectory control of the speed of DC Motor‚ especially when the motor and load parameters

Describe the main features of a DC electric motor and the role of each feature Part | Description | Role | Magnet(s) | Either permanent or electromagnetic. Induce a magnetic field and fit around the armature. | The magnets supply the magnetic field which interacts with the current in the armature to produce the motor effect. | Armature | The armature consists of a cylinder of laminated iron mounted on an axle. Often there are longitudinal grooves into which the coils are wound. | The armature
