Polarization

Type of polarization

Table 1. Polarization design area


1 Two coordinate systems are available:
  • A “Global” polarization coordinate system: The origin is positioned at the rotor center.
  • A “Local” polarization coordinate system that is specific to each considered magnet topology.
Note: The reference axis (X-axis for Cartesian coordinate system) has a red color.
2 Five strategies of polarization are proposed:
  • Direction
  • Radial +, Radial –
  • Orthoradial +, Orthoradial –
3 Definition of the polarization angle with a Direction as a strategy of polarization.

Table 2. Legend of pictures to illustrate the magnet polarization orientation


1 Global coordinate system. The origin is positioned at the rotor center. The reference axis is the X-axis. Its color is red.
2 Local coordinate system. Its location is defined for each magnet topology.

See the “Part Factory” application for more information. The reference axis is the X-axis. Its color is red.
3 Borders of the part sector in which magnet topology is defined.
4 Magnet in which point P is considered to illustrate the polarization orientation.
5 Polarization of the magnet considered at any point P.
