PROBLEM TO BE SOLVED: To provide a dynamo-electric motor easy to achieve its small body and low cost and having superior operation characteristics and a simple structure. SOLUTION: The dynamo-electric motor with a brush includes a magnetic pole group made up of permanent magnets of two multiple, which is not less than six, and a winding wire magnetic group made up of wires of three multiple, which is not less than nine. Three winding wires of the winding wire magnetic poles symmetrically positioned to the rotation axis are each connected in serial or in parallel, and the commutator has the electric poles of the same number as the winding wire magnetic poles, and three electrodes positioned symmetrically to the rotation axis are each connected directly. The dynamo-electric motor has one or plural brushes and each brush is so arranged that each brush is put in contact with an appropriate number of adjoining commutator electrodes.
