Presentation Transcript

  1. Eddy Currents and Eddy Current Losses • Solid Iron Core • Laminated Core ECE 441

  2. Eddy currents in a solid core • Eddy currents circulate within concentric shells, or loops • Voltages generated proportional to flux ECE 441

  3. Smaller paths reduce the eddy currents and voltages Eddy current loss is expressed as power Eddy currents in a laminated core ECE 441
