)記載の小型モータ。[Claims for Utility Model Registration] (1) A motor with a two-pole iron core, which creates a magnetic difference between the N-pole magnet and the S-pole magnet, draws the rotor core to one side, and connects the shaft and bearing. A small motor characterized by a structure that eliminates rattling between the parts and reduces noise. (2) The difference in magnetism between the N-pole magnet and the S-pole magnet can be determined by a grade difference based on the strength of magnetic flux, a gap difference between the magnet and the rotor core, or by providing holes, notches, depressions, etc. in the magnet. Claim (1)
) small motors.
