Notes and Changes:
Updated section 2.3 to capture change in production flag geometry from cylindrical to rectangular design.

Note that in section 5.2, it is suggested that the maximum magnet temperature may be only 80C. The max. operating temp for our type is 180C (see link below). This is much higher than the minimum for some NdFeB types (70C on this list): We are using the N35UH.
