"The only induction with a PM BL motor is the BEMF used for timing, so strictly speaking, I think these would be a 3-phase AC repulsion motor."
Besides timing, the BEMF is also used for braking and or regeneration. Strictly speaking, all (practical) electric motors use magnetic repulsion, these motors are called DC brushless motors. Obviously, no field coil is needed due to Perm Magnets.
