Claims

[Claims for Utility Model Registration] The stator is composed of permanent magnets with a number of poles of 2p that form a field on the inner peripheral surface of a cylindrical magnetic frame, and adjacent permanent magnets with different magnetic polarities are separated from the rotor through a slight air gap. The rotors are arranged so as to face each other, and the rotors are odd numbers m = 2n, where n is a natural number of 1 or more.
+1, and the number of poles p is prime with respect to an odd number m. A laminated core having m equally spaced rotor core teeth faces the inner circumferential surface of the permanent magnet of the stator, and their rotation The circumferential width of the child core teeth is smaller than the pole pitch of the permanent magnet, and each rotor core tooth has a concentrated winding armature coil, and these armature coils have m coils arranged in phase order. connected in a ring shape, and the connection points are sequentially connected to the commutator pieces, and a total of m and p of these commutator pieces are provided,
A DC motor with a concentrated winding armature and a multi-pole field, characterized in that each p segment is interconnected to have the same potential.
