Abstract

The motor (100) according to the present invention comprises: a stator (1) comprising an upper insulator (11), a stator core (12) and a lower insulator (13); a rotor (2) installed opposite to the stator (1) to rotate; a shaft (20) coupled to the rotor (2) to rotate together therewith; and a printed circuit substrate (3) electrically connected to the stator (1), wherein the rotor (2) comprises a rotor main body (21) and a magnet (22) coupled to an outer circumferential surface of the rotor main body (21), and the rotor main body (21) is made of an insulating material.

Description

Technical field [0001] The present invention relates to a motor. More specifically, the present invention relates to a motor having a new type of structure, by eliminating the ground structure of the motor and improving the motor, which can prevent damage caused by the bearing electrodes, and reduce the noise generated in the motor. Background technique [0002] Motors typically include stator and rotor. The magnetic field formed by the stator causes the rotor to rotate. The shaft is coupled to the rotor, rotating with the rotor, and the upper and lower portion of the rotor are supported by rotation of the axis. [0003] The motor is typically controlled by the drive circuit. When the drive circuit is operating, the potential difference between the bearing and the shaft is caused by the axial flow generated by other reasons. When the motor is working, electrical erosion generates noise and vibration, which adversely affects motor performance and motor durability. [0004] In orde...
