Motor

A motor comprising:

• a shaft;
• a rotor coupled to the shaft;
• and
• a stator disposed outside the rotor,
• wherein the rotor includes:
• a bearing holder including a cylinder portion and a flange portion;
• a first bearing disposed on one side of the cylinder portion;
• a second bearing disposed on the-an other side of the cylinder portion;
• a rotor core including a hole coupled to the cylinder portion;
• a magnet coupled to the rotor core;
• and
• a plate disposed below the rotor core,
• wherein the rotor core includes a pocket portion in which the magnet is disposed,
• the flange portion is disposed on the rotor core, and
• the plate is coupled to the other side of the cylinder portion.

A motor comprising:

• a shaft;
• a rotor coupled to the shaft;
• a stator disposed outside the rotor;
• and
• a first cover having a cylindrical shape and disposed outside the stator,
• wherein the stator includes a stator core and an insulator is disposed on the stator core,
• wherein the insulator includes an upper insulator and a lower insulator,
• wherein an outer circumferential surface of the stator core includes a first region and a second region,
• wherein the first region is disposed to be in contact with an inner circumferential surface of the first cover, and
• the second region is disposed above the first cover,.
• wherein the lower insulator is disposed inside the first cover, and
• wherein an inner circumferential surface the upper insulator is in contact with the second region.
