The author has collated the values available in the literature for the inclination of the AM Her systems, the angle between the magnetic axis and the rotation axis, and the azimuth of the magnetic axis from the line of centres of the two stellar components. The azimuths are clustered in a sector ≤90° wide with a mean value of ≅20°. This rules out the possibility of even small amounts of constant asynchronicity of the primary. Episodes of asynchronicity are ot excluded, but the data provide a weak limit on their duration relative to the locked episodes. Because of this, some non-dissipative mechanism is required to force the primary to rotate synchronously. Additional evidence is found for the clustering of the systems in the cos β, cos ι plane.
