Welcome to Module 16, which is about the basics of motors and motor control. An electric motor is a machine that converts electrical energy to mechanical energy. There are two main groups of electrical motors: DC and AC motors. This module will discuss both types of motors, and how to control them. FIGURE 1. TYPICAL ELECTRIC MOTOR
To build a simple motor, and analyze the relationship between current flow in a conductor in the form of a coil, the permanent and induced magnetic fields, and the resulting torque that turns the motor.
motor is a device that converts electrical energy into mechanical energy. Its basic parts are a rotang current-carrying coil of wire, a fixed magnet, and a commutator. The commutator switches the electrical leads to the coil as it rotates, so that the force always acts in the same direcon.
DC Motor Learning Objectives. Explain the role of a snubber diode. Describe how PWM controls DC motor speed. Implement a transistor circuit and Arduino program for PWM control of the DC motor. Use a potentiometer as input to a program that controls fan speed. LWTL: DC Motor.
Simple Electric Motor What makes the coil spin? Why doesn’t it stop like the single loop in the magnetic field?
An electric motor uses the attracting and repelling properties of magnets to create motion. An electric motor contains two magnets; in this science project, you will use a permanent magnet (also called a fixed or static magnet) and a temporary magnet. The temporary magnet is also called an electromagnet.
To build a simple motor, and analyze the relationship between current flow in a conductor in the form of a coil, the permanent and induced magnetic fields, and the resulting torque that turns the motor.
Simple Electric Motor. 3” long wooden dowels of 1” diameter and 1/4” diameter. Make the rotor by winding the 24 gauge insulated wire about 8 turns around the 1” wood dowel. Wrap the ends of the wire a couple of times around the 8 turns to hold them securely and leave about 1.5” of the wire on each end (see Figure 1).
The Electric Motor . 27.39 Schematic diagram of a simple dc motor. The rotor is a wire loop that is free to rotate about an axis; the rotor ends are attached to the two curved conductors that form the commutator. (The rotor halves are colored red and blue for clarity.) The commutator segments are insulated from one another.
Circuit Diagram Of Simple Electric Motor. > HERE<<< An electric circuit needs three basic things to work: 1. the circuit. This could be in the form of a light bulb, a resistor, a motor or other electrical components. Draw a circuit diagram to show how you connected the components in your circuit.
Basic DC Motors. The most simplest DC motor has a stationary set of magnetic poles. This is called the stator. The stator can use permanent magnets or electro-magnets which creates a stationary magnetic field. The stator can have multiple magnetic fields.
Purpose: to know how to make simple motors and know the basic principles upon which motors work. Procedure 1. Cut about two feet of magnet wire. 2. Form a loop with the wire (this can be done by wrapping the wire around the battery) 3. Pull back about an inch of wire from the loop to make leads (whiskers) to
Fundamentals of Electric Motors •Overview/Objectives: o Basic motor function o Basic motor components o Basic motor application and performance
Activity 1: Building the simplest electric motor. Steps to building the motor. -Use the two rubber band to attach the bare copper wires to the plastic cup. -Clamp an alligator clip to one end of each of the bare copper wires.
a simple handmade electric motor. Constructing and analysing a simple motor provides students with a fun and interesting hands-on experience that helps make concrete complex abstract ideas like the magnetic field due to loops and coils, the magnetic field due to a permanent magnet, flux, torque, back EMF and so forth [1–5].
build a simple electric motor and describe how it works; list some of the ways motors are used at home; explain the role generators play in producing electricity; describe the energy conversions that take place in a motor and generator; and. identify the similarities between motors and generators.
A student has made a simple electric motor. The diagram shows the electric motor. (a) Complete the following sentence by drawing a ring around the correct line in the box. the cell Once the coil is spinning, one side of the coil is pushed by the coil and a force the other side is pulled, so the coil continues to spin.

W e describe the construction and the conceptual and introductory level mathematical analysis of a simple handmade electric motor . Constructing
Chapter 3. Material taken from Chapter 3 of Electric Motor Controls, G. Rockis, 2001. One-Line Diagrams. One-line diagram – a diagram that uses single lines and graphic symbols to indicate the path and components of an electrical circuit.
(c) The G-machine is rotated by an electric motor. The diagram shows a simple electric motor. The following statements explain how the motor creates a turning force. The statements are in the wrong order. M – The magnetic field interacts with the magnetic field of the permanent magnets. N – A magnetic field is created around the coil.
