Application of dc drives

We provide drive applications for both DC and AC motors. We use drives manufactured by Emerson Industrial Automation (Control Techniques). For simple applications , we offer AMD drives.

Designs based on dc drives excel in an array of industries.

No attempt will be made to have this summary exhaustive but rather it will cover some common applications.

Description and Applications ).

Brushed (Field Energised) Motors (Motors using wound rotors).

The traditional DC motor needs two current supplies, one through the stator windings to provide the magnetic field and the other through the rotor windings to interact with the magnetic field to generate . Drives - Information on drives and drive systems including different types of electrical AC and DC drives and their applications. DC drive technology is efficient, reliable, cost effective, operator friendly and relatively easy to implement. DC drive provides many advantages over AC drives , especially for regenerative and high power applications.

DC drives have been widely used in industrial drive applications in order to offer very . DC motors and thyristor drives remain common in many industries. Control Techniques offers modern DC drives and field controllers that enhance performance, reliability and system integration options.

The primary reasons include the ruggedness of the electric machine, the drive and the ability to provide large horsepower speed control. The ability of the DC machine to operate in each of the Four Torque Quadrants . AC slip ring motors with speed control. The DC motors, because, of their inherent characteristics, are best . AC Drive Advantages, DC Drive Advantages.

Use conventional, low cost, 3- phase AC induction motors for most applications. Less complicated due to single- power conversion (AC to DC only). AC motors require very little maintenance and are preferred for applications where the motor is mounted in an area not easily . The paper deals with the applications of artificial neural networks in the control of the DC drive.

In the paper three control structures are discussed. The speed and torque of induction motors can be controlled by – Stator voltage control . Consider regenerative power in this case . Since the series-wound DC motor develops its highest torque at low spee it is often used in traction applications such as electric locomotives, and trams. Conventional AC operated crane drives use slip ring induction motor whose .
