Presentation on theme: "The Direct Current (DC) Electric Motor"— Presentation transcript:
1 The Direct Current (DC) Electric Motor What you need to know:Electromagnetismmain parts of the motorFlow of electricity through the motorinteraction of opposing magnetic fields
2 Starting Motor Fundamentals An automobile uses many DC motors in various systems. The main application of a DC motor is the engines starter motor.What the starter motor does:Converts electrical energy from the battery to mechanical energy to crank the engineProduces a turning force through the interaction of magnetic fields inside the motor
3 Magnetic Field Action Made up of invisible lines of force Since like charges (fields) repel each other and unlike charges (fields) attract each other, magnetic fields can produce motion
12 Know this diagram and be able to label these parts This is a cutaway view of a starter motor.
13 The Starter Motor Circuit A short video on the automobiles starter motor circuit.
14 The DC Motor PrincipleA Short video explaining the interaction of magnetic fields between the armature and field coils.
15 What to Know for the Exam For the exam you will need to know:1. basic components: armature, pole shoes/field coils, commutator, brushes, solenoid2. Be able to explain the basic dc motor principle….how magnetism is formed, and how opposing magnetic poles create rotation in the motor.
