There is provided a spindle motor including: a sleeve fixedly installed on the base member and having a circulation hole formed therein; a shaft rotatably inserted into a shaft hole of the sleeve; a rotor hub fixedly installed on an upper end portion of the shaft; and a thrust member installed in an installation groove of the sleeve and forming a connection part while being installed in the installation groove, the connection part being connected to the circulation hole, wherein the connection part is formed by the sleeve and the rotor hub and connects a sealing part in which a liquid-vapor interface is disposed and the circulation hole to each other, and an upper and lower radial dynamic grooves allowing a lubricating fluid to move from a lower end portion of the shaft toward the upper end portion thereof during rotation of the shaft.

Spindle motor and recording disk driving device including the same

The vibration motorof the present invention comprises a housing, a rotating shaftbeing rotatably installed in the housingand having a recessformed on an outer periphery thereof, a commutatorbeing fixedly combined with the shaft, and a blocking bodywith a small thickness being forcibly inserted into the recessand fixedly combined with the commutator, wherein the commutatorand the blocking bodyare fixedly combined with each other by an predetermined adhesive.

Vibration motor provided with a thin blocking body of a communtator's breakaway

A bar-type vibration motor has a stator unit including a body and a magnet attached in the body; a rotor unit including a rotary shaft having one end fixed to an eccentric weight and the other end fixed to a stationary member, a portion of the rotary shall adjacent to the eccentric weight being rotatably supported by the body like a cantilever, a commutator having several segments attached on one side of the stationary member, and an armature fixed to the stationary member spaced apart from the magnet, and electrically connected with the commutator; and a power supply unit including a fixing cap faxed to the body and a brush mounted on the fixing cap to supply voltage to the armature.

Bar-type vibration motor

A bar type vibration motor includes a stator unit including a body having a bearing insert groove formed at one end thereof and exposed to the outside, and a magnet attached to the body; a rotor unit including a rotary shaft having one end fixed to an eccentric weight, both ends of the rotary shaft being rotatably supported in the body, and an armature fixed to the rotary shaft at a space from the magnet; and a power supply unit including a fixing cap fixed to the body and brushes mounted on the fixing cap to supply voltage to the armature.
