Applications of the Motor Effect

Electromagnetism >

Inquiry question: How has knowledge about the Motor Effect been applied to technological advances?

Students:
● investigate the operation of a simple DC motor to analyse:
– the functions of its components
– production of a torque 𝜏 = 𝑛𝐼𝐴⊥𝐵 = 𝑛𝐼𝐴𝐵sin𝜃
– effects of back emf (ACSPH108)
● analyse the operation of simple DC and AC generators and AC induction motors (ACSPH110)
● relate Lenz’s Law to the law of conservation of energy and apply the law of conservation of energy to:
– DC motors and
– magnetic braking
