ABSTRACT:
A disk-type brushless motor comprises a 2p-pole magnet rotor (p represents an integer of 2 or more) having alternating N and S poles and a single position sensor element. A stator armature having an armature coil is formed on two conductors which contribute to the generation of torques and extend with an opening angle substantially equal to the width of each magnetic pole of the magnet rotor. A projection such as a screw for generating cogging to enable the self-start of the magnet rotor is disposed at a place somewhere short substantially by a width
