Investigation of relationships of adjustable speed drive (ASD) and type of voltage source on harmonic characteristics
(Universiti Malaysia Perlis (UniMAP), 2012-10-16)
This paper discussed about relationship of ASD and
types of voltage source on harmonic characteristics.
Usually, the voltage source is sinusoidal. But in
actually, the condition of the load is it has voltage
sources ...
Effect of different size of rotor bars on induction motor efficiency
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Efficiency is the main consideration in designing of any equipment. In an induction motor, there are many parameters that could affect the motor efficiency. One of them is the size of rotor bar, that contribute to the rotor ...
