Abstract

Provided is a fan motor apparatus. The fan motor apparatus includes a rotor and a stator. The rotor includes a blade. The stator includes a rotor supporting mechanism, a supporting member, and a vibration insulation member. The rotor supporting mechanism rotatably supports the rotor. The supporting member supports the rotor supporting mechanism. The vibration insulation member is provided between the rotor supporting mechanism and the supporting member. The stator is capable of regulating relative movement of the rotor supporting mechanism and the supporting member.

Claims

1. A fan motor apparatus, comprising:

a rotor including a blade; and

a stator including a rotor supporting mechanism rotatably supporting the rotor, a supporting member supporting the rotor supporting mechanism, and a vibration insulation member provided between the rotor supporting mechanism and the supporting member, the stator being capable of regulating relative movement of the rotor supporting mechanism and the supporting member.

2. The fan motor apparatus as set forth in claim 1, wherein the stator includes a first rib provided to the rotor supporting mechanism and having an end portion being a first tapered surface, and a second rib provided to the supporting member and having an end portion being a second tapered surface which is provided such that the second tapered surface opposes the first tapered surface, and

wherein the vibration insulation member is a tube-shaped member connecting the end portion of the first rib and the end portion of the second rib.

3. The fan motor apparatus as set forth in claim 2,

wherein the first rib is elastically provided to the rotor supporting mechanism.

4. The fan motor apparatus as set forth in claim 2,

wherein the second rib is elastically provided to the supporting member.

5. The fan motor apparatus as set forth in claim 1,

wherein the stator includes a first rib provided to the rotor supporting mechanism and including a first engagement portion, and a second rib provided to the supporting member and including a second engagement portion engaged with the first engagement portion.

6. The fan motor apparatus as set force in claim 5,

wherein the vibration insulation member is a tube-shaped member connecting the first rib and the second rib such that the first engagement portion and the second engagement portion are covered.

7. The fan motor apparatus as set force in claim 1,

wherein the stator includes a first rib provided to the rotor supporting mechanism and having an end portion, and a second rib provided to the supporting member and having an end portion connected to the end portion of the first rib through the vibration insulation member, and

wherein the vibration insulation member is provided such that a gap formed between the end portion of the first rib and the end portion of the second rib is sealed.

8. An electronic apparatus, comprising:

a heat generator;

a fan motor including a rotor including a blade, and a stator including a rotor supporting mechanism rotatably supporting the rotor, a supporting member supporting the rotor supporting mechanism, and a vibration insulation member provided between the rotor supporting mechanism and the supporting member, the stator being capable of regulating relative movement of the rotor supporting mechanism and the supporting member; and

a case accommodating therein the heat generator and the fan motor.
