International Classification:

H02K 7/18

US Classification:

290 1R, 290 54, 290 40 C

Abstract:

A power source that is powered by a user to generate electrical energy includes a generator assembly and a fluid source. The generator assembly includes a rotor, a stator, and a fluid driven motor that is coupled to the rotor. Movement of the rotor relative to the stator results in the generation of electrical energy. The fluid source is manually powered by the user to direct pressurized fluid to the fluid driven motor to move the rotor relative to the stator. The fluid source can include a first fluid pump that is powered by the user to generate the pressurized fluid and a second fluid pump that is powered by the user to generate the pressurized fluid. One or both of the fluid pumps can include a fluid bellows that is powered by the user to generate the pressurized fluid. Alternatively, one or both of the fluid pumps can include a cylinder and a piston that is moved within the cylinder by the user to generate the pressurized fluid.

Abstract:

In a disk drive including a conventional head and disk assembly containing a spindle motor for rotating a disk hub at a constant angular velocity and at least one rotating disk mounted to the hub, apparatus comprising a base having a peripheral sidewall surrounding the base. The base supports the head and disk assembly within an interior space defined by the peripheral sidewalls in combination with the base. To reduce the power consumption as well as the operating temperature of the disk drive by controlling and confining the air mass proximate the disk, a shroud is positioned within the interior space and proximate the disk such that the shroud substantially circumscribes the circumference of the disk for an arc of approximately 320 degrees.
