Publication number: 20160010649Abstract: A fan assembly having a reduced dimension formed by several modifications is described. The fan assembly includes a stator having stator coils positioned within a recessed portion of a pillow that receives the motor. The stator may include wire connections positioned between adjacent stator coils and designed to terminate wires of the stator coils. The wire terminations may be on a protrusion or a post positioned between adjacent stator coils, or alternatively, the wire terminations may be disposed on protruding features of a bushing. The protrusion may be formed from an electrically conductive material and electrically connected to a motor control circuit via a flexible printed circuit. In some embodiments, the protrusion is part of an electrically neutral stator bushing having several pins. Also, a gap region between the bushing and a flange feature is designed to improve an adhesive joint.Type: ApplicationFiled: July 9, 2015Publication date: January 14, 2016Inventor: Anthony Joseph Aiello

Publication number: 20150152883Abstract: The described embodiments relate to improving efficiency of a low-profile cooling fan. In one embodiment, an impeller of the cooling fan includes a shroud which covers a central portion of the impeller, thereby allowing a central inlet portion of the blades to have an increased fan blade height when compared to a cooling fan constrained by minimum part tolerances between the fan blades and a portion of the fan housing. In some embodiments, the impeller includes splitter blades that can improve performance of the low-profile cooling fan.Type: ApplicationFiled: December 3, 2014Publication date: June 4, 2015Inventors: Jesse T.

Publication number: 20140301828Abstract: The described embodiments relate generally to improving performance characteristics of a low profile fan. More specifically configurations having sloped fan blade edges are disclosed. By applying a gradual slope to each of the fan blades, performance of the fan can be increased without risking contact or rubbing between the fan blades and a fan housing. In some embodiments, the sloped fan blades can be configured to prevent contact when bearings of the fan include a certain amount of tilt play.Type: ApplicationFiled: May 3, 2013Publication date: October 9, 2014Applicant: Apple Inc.Inventors: Anthony Joseph Aiello, Jesse T. Dybenko, Richard A. Herms

Publication number: 20140265963Abstract: A method to reduce acoustic noise in a cooling fan motor is disclosed. The method includes reducing the slew rate of a PWM (pulse width modulation) voltage waveform applied to energize a coil of the fan motor. This slew rate reduction results in lower mechanical vibrations and acoustic noise in the fan motor. In one embodiment, the slew rate reduction is performed during startup of the fan motor, when the motor is spinning slowly and there is little air flow noise. In another embodiment, the slew rate reduction is not performed during high speed operation of the fan motor, when the fan motor is spinning very fast and air flow noise masks the motor noise. In one embodiment, there is variable slew rate control depending on the speed of the fan motor.Type: ApplicationFiled: March 11, 2014Publication date: September 18, 2014Applicant: Apple Inc.Inventors: Brad Lee Patton, Anthony Joseph Aiello, Jesse T.

Publication number: 20140139948Abstract: A fluid dynamic bearing motor and method are provided for use with various disc drive memory device products differently rated by operational rotational speed. The operational speeds are those speeds measured during reading and writing memory operations to the memory device. In an aspect, the present invention meets full operating requirements, including stiffness and power requirements, at multiple rated speeds for use with either standard or high-end performance disc drive products. Costs associated with a dedicated manufacturing line for high-end products are substantially reduced. A single manufacturing line can serve both standard and high-end disc drive memory device products. The present invention is especially useful in reducing costs of 2.5 inch notebook products that are typically marketed in two levels of performance, namely, 5400 RPM standard performance products and 7200 RPM high performance products.Type: ApplicationFiled: April 12, 2013Publication date: May 22, 2014Applicant: SEAGATE TECHNOLOGY LLCInventors: PohLye Lim, PowMing Yap, ChunHong D.

Patent number: 8699182Abstract: An apparatus includes a hub, a first disk, a second disk, and a spacer. The hub is supported for relative rotation about a stationary component. The first disk is mounted to the hub with a first dynamic resonance mode associated therewith. The second disk is mounted to the hub with a second dynamic resonance mode associated therewith. The spacer is positioned between the first disk and the second disk, wherein the spacer is operable to cause the first dynamic resonance mode to be different from the second dynamic resonance mode.Type: GrantFiled: September 17, 2012Date of Patent: April 15, 2014Assignee: Seagate Technology LLCInventors: Anthony Joseph Aiello, Xiong Liu, Hans Leuthold, Chuen Buan Lee, Choon Kiat Lim, Chris Michael Woldemar

Publication number: 20140049906Abstract: A fan assembly for a computing device is disclosed. The device can include an impeller having a number of blades and a motor for turning the blades. The motor can turn the blades via a magnetic interaction between the impeller and the motor. A fluid dynamic thrust bearing can be used to control a position of the impeller relative to the motor. In particular, the impeller can be configured to rotate around an axis and the thrust bearing can be used to control movement of the impeller in a direction aligned with the rotational axis. In one embodiment, the thrust bearing can be configured to stabilize the impeller when vibratory forces act upon the fan assembly. More particularly, parameters associated with the thrust bearing can be selected to counteract vibratory forces emitted by a speaker system.Type: ApplicationFiled: October 23, 2013Publication date: February 20, 2014Applicant: Apple Inc.Inventors: Anthony Joseph Aiello, Jesse T.

Publication number: 20110064342Abstract: A typical dynamic bearing design comprises a ring shaped or circular thrust plate mounted at or near the end of a shaft, the shaft defining together with a surrounding sleeve a journal bearing by providing grooves on only one of the two surfaces facing the gap between the shaft and sleeve. On the ring shaped thrust plate supported by the shaft, the traditional upward thrust bearing defined between the lower face of the thrust plate and the facing surface of the sleeve is maintained; but no grooves are on the surface of the thrust plate distant from the shaft and a facing counterplate surface. Further, the journal bearing is defined to have an asymmetry so that a bias force pressure along the surface of the shaft toward the thrust plate is established.Type: ApplicationFiled: November 19, 2010Publication date: March 17, 2011Applicant: SEAGATE TECHNOLOGY LLCInventor: Anthony Joseph Aiello
