Presentation Transcript

  1. ELCT 553 Electromechanical Energy Conversion Magnetic Circuits Power Transformers Actuators DC and AC Machines (motors and generators) ELCT 553

  2. Electromechanical Energy Conversion • Conversion of electrical energy to mechanical energy (a motor, for example) • Conversion of mechanical energy to electrical energy (a generator, for example) • Also transformers convert electrical energy from one voltage to another or couple two circuits together ELCT 553

  3. Coupling Field • All electromechanical energy conversion devices use a coupling field to perform the conversion • Electric fields are used but not often • Magnetic fields are used often • Energy density favors magnetic devices • Micro and nano sized devices may use E field ELCT 553

  4. Transformer • Electrical energy to electrical energy, but also uses a coupling field (magnetic field almost always) • Consider an iron core having two coils ELCT 553

  5. Magnetic circuit: Iron core with one or more coils I H N turns V ELCT 553

  6. fc F = NI Rc Magnetic circuit ELCT 553

  7. I fc N turns V ELCT 553

  8. Magnetic circuit: Iron core with one or more coils I1 I2 fc V1 V2 N1 turns N2 turns ELCT 553

  9. fc Rc F2 F1 Magnetic circuit ELCT 553

  10. Magnetic circuit: Iron core with one or more coils I1 fc V1 Air gap length = g Average iron core length = lc N turns ELCT 553
