PROBLEM TO BE SOLVED: To provide a structure of a motor that secures efficiency, when of the turning of the rotor, maintains stability at the start of the rotor, and further can keep balance in rotation. SOLUTION: At least one set of coil winding and a plurality of magnetic pole faces are formed in a set of stators provided at a fixing section, and a magnetic pole gap is formed between two adjacent pole faces each. An annular magnet provided in the rotor is formed, while the annular magnet corresponds to the magnetic pole surface of the set of stators. At least two magnetic conduction surfaces are provided in a magnetic conduction balancing piece provided at the fixing section. The magnetic conduction surface is positioned at a position between the magnetic pole gaps of the set of stators, and is formed, while the magnetic conduction surface faces the annular magnet of the rotor. When the rotor is turned, the annular magnet of the rotor induces the alternating magnetic field of the magnetic pole surface and performs magnetic attraction corresponding to the magnetic conducting surface.
