Electric Motors
EXERCISE NO. 1
ELECTRIC MOTORS
I. Introduction
Electric motors are considered to be important mechanical devices. They usually convert the electrical energy coming from the mechanical device into its kinetic energy to make it work (Petingco and Resurreccion, 2011). In this exercise, the students were tasked to use an example of an electric motor, identify its parts, and make it work.
All electrical motors are equipped with stator and rotor. Stator is known as the stationary part of an electric motor while rotor as the term implies, refers to the rotational part of the electric motor. Furthermore, it can be classified into two types of motor enclosure namely: (1) open-type enclosure; and (2) closed-type enclosure.
To easily distinguish the two motor enclosures, closed-type motor enclosure is the one who has an existing fan in its unit. This fan serves to lessen the excess heat that was brought to the electric motor. With electric motors, it is also important to check for the existence of a name plate. A name plate contains all the necessary information that a buyer should know before buying the actual product. And lastly the students were tasked to come up with the necessary wiring combinations that will allow them to make a certain electric motor to work. navigate
II. Objectives
The measurement made also aided in further
A. To become familiar with the external construction and parts of electric motors;
B. To become familiar with electric motor specifications;
C. To perform proper wiring of the electric motor;
D. To perform simple measurements; and
E. To modify selected motor specifications
III. Materials
Electric motors Circuit breaker Vernier caliper
Clamp-on ammeter Push button switch Steel tape
Tachometer Hand tools Weighing scale
IV. Methodology
The exercise was divided into two parts. The first involved the observation of the electric motor. The students were shown the assigned electric motor for each group and were
