Motor and Electric Apparatus Using the Same Motor
A motor includes a stator formed of an iron core wound with windings, a rotor placed opposing to the stator, a rotary shaft coupled to the rotor, a bearing holder for holding a bearing that supports the rotary shaft, and plural cooling fins placed around the bearing holder.
1 . A motor comprising:
a stator of which iron core is wound with windings;
a rotor disposed opposing to the stator;
a rotary shaft coupled to the rotor;
a bearing holder for holding a bearing that supports the rotary shaft; and
a plurality of cooling fins disposed around the bearing holder.
2 . The motor of claim 1 , wherein the bearing holder is made from resin.
3 . The motor of claim 1 , wherein the stator and the bearing holder are formed into one body by insulation resin.
4 . The motor of claim 1 further comprising a bracket, at which the bearing holder is formed.
5 . The motor of claim 1 further comprising a bracket, at which the bearing holder is formed, and the stator and the bracket are formed into one body by insulation resin.
6 . An electric apparatus comprising:
a motor; and
a housing in which the motor is mounted, wherein the motor includes:
a stator of which iron core is wound with windings;
a rotor disposed opposing to the stator;
a rotary shaft coupled to the rotor;
a bearing holder for holding a bearing that supports the rotary shaft; and
a plurality of cooling fins disposed around the bearing holder.
7 . The electric apparatus of claim 6 , wherein the bearing holder is made from resin.
8 . The electric apparatus of claim 6 , wherein the stator and the bearing holder are formed into one body by insulation resin.
9 . The electric apparatus of claim 6 further comprising a bracket, at which the bearing holder is formed.
10 . The electric apparatus of claim 6 further comprising a bracket, at which the bearing holder is formed, and the stator and the bracket are formed into one body by insulation resin.
