Harmonics Reports Samples For Students

PURPOSE

This experiment is about the isolation of the three harmonics that is included in a non-sinusoidal waveform. The non-sinusoidal waveform here is a square wave, and the harmonics being isolated are the fundamental, third, and fifth harmonics. The experimental amplitudes and frequencies will be compared to the theoretical computations.

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 ...

Lab Report

Objective: To explore the characteristics of three single-phase transformers in a three-phase configuration.

- Star- Star (Y-Y) Connection
In star- star or Y-Y connection, each phase is 120° out of period with the extra two periods. In the same way, each secondary winding is 120° out of phase with the other two phases. Every primary winding is magnetically connected with secondary winding using the common leg. When talking about primary to secondary phases we will see that there is no phase difference in primary-secondary connections. It simplifies that both, primary and derived ...

Introduction

Signals that are periodic can be represented in time and frequency. In any analysis there are major signals which are used; these signals include sine, triangle and square. Additional signals can be derived from the three main signals. There is an important component in signal technology, the low pass filter. This is an electronic gadget that used in the filtering process of the signals. The filtering process is undertaken by allowing all the frequency components that come below the cut-off frequency to go through the circuit while all other frequencies that are above cut-off frequency will be bypassed. Noise ...
