Electric Speed Governor for 1kw Microhydro Generator

Human as an Electric Generator

“The idea is to generate electric energy from the mechanical movements of living beings”. When living beings make mechanical movements, they spend their energy some of which is converted to work. The wasted energy can be converted to electrical energy with the help of nano-generators. The nano generators have a piezo electric crystal (say ZnO) which is made up of nanoparticles. These piezo elec...

Designing a Coreless High-Speed Axial-Flux PM Generator for Microturbines

Automatic Phase Advancing in Switched Reluctance Motor by Employing an Electronic Governor for a Desired Speed Angle Profile

Switched reluctance motor (SRM) drive has remarkable characteristics that make it attractive for high-speed applications. As the motor's speed increases the shape of the current waveform changes in such way that limits the production of motoring torque. At high speeds, it is possible for the phase current never reaches the desired value due to the self e.m.f. of the motor, therefore, the torque...

Application of Speed Estimation Techniques for Induction Motor Drives in Electric Traction Industries and vehicles

Induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. Speed identification is needed for the induction motor drives. However, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. Ther...

Thermo-Magneto-Electric Generator Arrays for Active Heat Recovery System

Continued emphasis on development of thermal cooling systems is being placed that can cycle low grade heat. Examples include solar powered unmanned aerial vehicles (UAVs) and data storage servers. The power efficiency of solar module degrades at elevated temperature, thereby, necessitating the need for heat extraction system. Similarly, data centres in wireless computing system are facing incre...
