Abstract
A flat collectorless motor is described whose rotor has been provided with an axially magnetized annular magnet which cooperates with axial bounding surfaces of the stator poles outside the stator coil ends, which enables the axial height of the stator iron to be reduced without reducing the effective surface area of the stator teeth. This construction enables Hall elements to be mounted on a p.c. board, which Hall elements are arranged in the main field of the rotor magnet.
