Abstract

Permanent magnet synchronous motors (PMSM) are a type of motors that have permanent magnets mounted on the rotors instead of the rotor windings. This particular design gives the motor a few advantages over ordinary induction synchronous motors. The magnets attached to the rotor do not require excitation, which reduces the power consumption in PMSM. This gives the motor high operational efficiency and reduces the motor active diameter. PMSM are therefore associated with applications that require high torque but have limited operation space. The permanent magnets suffer from flux leakage and are therefore aligned in a pattern that minimizes flux ...

Introduction:

In a typical hydroelectric power generation system, a dam (water reservoir) is built near water body such as a river to create head (height) that enables water to flow at high pressure via a pipe (penstock) to the turbines that drive the power generators. The fast moving water turns the turbine blades at high velocity, and in turn, the turbine turns the electricity generator’s rotor. The wire coils in the generator’s rotor sweep past the stationary coil (stator) in the generator thus producing electricity. This concept was first demonstrated in 1831 by Michael Faraday, who discovered that ...

At first glance one would think that Philippe Starck’s iconic juicer was a spider-inspired piece of artwork due to the three long legs that supports what seems to be a rocket ship-shaped body. Surprisingly, the designer actually thought of the similar inspiration. The juicer is now considered as an icon of contemporary industrial design; it even earned its place in New York’s Museum of Modern Art. However, the juicer itself according to Starck was intended to be a conversation piece rather than a juicer. In 1989, Alessi originally approached the Italian designer to design a stainless steel tray, but after a trip to a ...
