Claw pole type motor
View Patent ↗A claw pole type motor is provided and includes: a rotor which includes a magnet and a rotation shaft around which the magnet is attached; and a stator which includes a bobbin, a winding wound around the bobbin, and a yoke which includes a plurality of pole teeth disposed to oppose the magnet and which is located outside the winding, wherein a vibration suppressing means is provided which makes contact with a distal end portion of the pole tooth and by which the pole tooth is pressure-supported on an inner circumferential surface of the bobbin, whereby the pole tooth is suppressed from vibrating.
1. A claw pole type motor comprising:
a rotor which includes a magnet and a rotation shaft around which the magnet is attached;
a stator which includes a bobbin, a winding wound around the bobbin, and a yoke which includes a plurality of pole teeth disposed to oppose the magnet and which is located outside the winding; and
a vibration suppressing means which makes contact with a distal end portion of the pole tooth, and by which the pole tooth is pressure-supported on an inner circumferential surface of the bobbin, whereby the pole tooth is suppressed from vibrating.
2. The claw pole type motor according to claim 1 , wherein the vibration suppressing means is formed integrally with the bobbin when the bobbin is produced.
3. The claw pole type motor according to claim 1 , wherein the vibration suppressing means is formed at a ring-shaped member which is inserted at the inner circumferential surface of the bobbin.
4. A claw pole type motor comprising:
a rotor which includes a magnet and a rotation shaft around which the magnet is attached;
a stator which includes a bobbin, a winding wound around the bobbin, and a yoke which includes a plurality of pole teeth disposed to oppose the magnet, and which is located outside the winding; and
either a protruding portion or a bent portion which is disposed at a distal end portion of the pole tooth, and which makes contact with an inner circumferential surface of the bobbin thereby working as a vibration suppressing means, whereby the distal end portion of the pole tooth is pressure-supported on the inner circumferential surface of the bobbin.
5. A claw pole type motor comprising:
a rotor which includes a magnet and a rotation shaft around which the magnet is attached;
a stator which includes a bobbin, a winding wound around the bobbin, and a yoke which includes a plurality of pole teeth disposed to oppose the magnet and which is located outside the winding; and
a vibration suppressing part which makes contact with a distal end portion of the pole tooth, and by which the pole tooth is pressure-supported on an inner circumferential surface of the bobbin, whereby the pole tooth is suppressed from vibrating.
