Title:

MAGNET ROTOR TYPE MOTOR AND PUMP INCLUDING THE SAME

Document Type and Number:

Japanese Patent JP2015220910

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a motor which has a simple configuration, is excellent in assemblability, water-resistance, and water proofness, and exhibits a long term stability in lubrication property of a rotation member.SOLUTION: A magnet rotor type motor includes a resin-molded stator assembly and a rotor assembly holding a cylindrical shaped magnet rotor which is magneto-electrically driven by the stator assembly. The stator assembly includes a stator core member formed by stacking, a resin molded body formed by resin molding the stator core member, and a center shaft attached to the resin molded body. The rotor assembly includes a rotor center body which penetrates and holds the magnet rotor. The rotor center body includes a bottomed center shaft hole, and bears the center shaft via a bearing arranged in the center shaft hole so as to rotatably support the rotor assembly. In this type of a magnet rotor type motor, lubrication oil oozing out when operating a device does not flow out to the outside.
