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 ? = ???⊥? = ????sin?

– 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
