Latest Patents

Wada's latest patents include a spindle motor with a bearing system that features fluid sealing and leakage prevention. This invention involves a spindle motor that includes a rotor hub bearing a rotational load, lubricant-containing bearing systems that are rotatably supported by the rotor hub, and stator windings wound on a stationary member. The design ensures that at least a portion of the rotor hub is in a clean environment, with the motor being substantially sealed by a sealing unit. The spindle motor is equipped with a leakage prevention unit that stops lubricant from leaking out of the bearing systems and the motor, even when high centrifugal forces are exerted on the lubricant.

Another significant patent is the connector-equipped spindle motor. This design features a stationary shaft and a rotor hub that is rotatably supported by the stationary shaft via a bearing. A loop-like rotor magnet is attached to the internal surface of the rotor hub, with a stator positioned to face the rotor magnet. The stationary shaft has an opening at its base end where a connector is fitted. This connector allows for electrical connection to an external unit, enabling power supply to the coil from the external source.
