Introduction • Electrical energy is utilized in many forms. Driving load by electric motor is one such application. • Electric drives are quick to start, have high efficiency and the speed can be easily controlled. • Different motors have different characteristics and depending upon load characteristics, the motor with suitable characteristics can be chosen for a particular applications. • Hence electric drives are widely preferred ...
7. CLOSED LOOP MOTION CONTROL IN ELECTRIC DRIVES 7.1. INTRODUCTION By motion control we mean torque, speed or position control. Motion control systems are characterized by precision, response quickness and immunity to parameter detuning, torque and inertia perturbations and energy conversion rates. Motion control through electric motors and power electronic converters (P.E.Cs) may be approached by the theory and practice of linear ...

Why should we care? For the environment For the bottom line Why should we care? For the environment Replacing a worn-out drive belt can drive big environmental gains. Why should we care? For the bottom line Installing variable speed drives can result in energy savings of 40 to 60 percent. Fans and Pumps Fans provide the motive force to move air against the resistance of ...
Synchronous Machines • Synchronous generators or alternators are used to convert mechanical power derived from steam, gas, or hydraulic-turbine to ac electric power • Synchronous generators are the primary source of electrical energy we consume today • Large ac power networks rely almost exclusively on synchronous generators • Synchronous motors are built in large units compare to induction motors (Induction motors are cheaper for smaller ...
