1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

fasteners . Wood screw Generally has an unthreaded portion of the shaft below the head. It is designed to attach two pieces of wood together. Particle board screw Similar to a drywall screw except that it has a thinner shaft and provides better resistance to pull-out in particle board‚ while offset against a lower shear strength.

that allows you to talk to and listen to. This device is called the handset. The handset is usually made out of plastic and inside it are two main components: the transmitter and the receiver. THE TRANSMITTER It is the job of the transmitter to turn the air pressure created by your sound waves to electrical signals so they can be sent to the other telephone. The waves hit a thin skin called the diaphragm that is physically connected to a reservoir of carbon granules. When the pressure hits the

Lab: Ionic and Covalent Bonds Objectives • Understand the differences between ionic and covalent bonds. • Connect ionic and covalent bonds with physical properties of matter. Introduction Sugar and salt look so similar that most people cannot tell them apart without tasting them. Chemically‚ white refined table sugar‚ sucrose‚ and salt are very different. An ionic bond between a positive sodium ion and a negative chloride ion creates a molecule of sodiumchloride (NaCl). Covalent bonds between

Elasticity is the ability of an object or substance to return quickly to its original shape and size after being bent‚ stretched‚ or squashed. When an elastic material is deformed due to an external force‚ it experiences internal forces that oppose the deformation and restore it to its original state if the external force is no longer applied. There are various elastic moduli‚ such as Young’s modulus‚ the shear modulus‚ and the bulk modulus‚ all of which are measures of the inherent stiffness of
