Definition of homopolar in US English:



  • 1Having equal or constant electrical polarity.

    • ‘In order for the homopolar motor to fully exploit the advantages of reduced size and weight, the field coils must be superconducting.’
    • ‘When I was trying to understand homopolar machines recently, it was wonderful to find your ‘balancing D-cell’ homopolar motor at the end of this page.’
    • ‘The magnetizing flux of a hybrid motor flows along the rotor axis, while the mechanism for rotor suspension is the same as that of the homopolar magnetic bearing.’
    • ‘Here is about as simple a motor as you can get - the old homopolar motor.’
    • ‘Here, I survey the results of our investigation of the atomic structure of dislocation cores in homopolar semiconductors.’
    1. 1.1 (of an electric generator) producing direct current without the use of commutators.
      • ‘I currently have measured results from a simple homopolar design I am using to experiment with.’
      • ‘Figure 1 is a sectioned isometric view showing a homopolar generator.’
      • ‘Each roller magnet in the Searl device is a small homopolar generator and the entire set of rollers create a radial Lorentz force too.’
      • ‘Since then, brush gear has been designed, manufactured and installed, and large-scale tests have been made with this gear in the homopolar generator.’
