Abstract

The invention relates to a motor interconnect device. 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.

Description

technical field [0001] The described embodiments generally relate to components within electronic devices. In particular, embodiments herein relate to an electronic device having an electric motor with a reduced height, which may allow for a reduction in size of the electronic device. Background technique [0002] Centrifugal fans are often used in computing systems and other electronic devices to provide cooling for central processing units (CPUs), graphics processing units (GPUs), and / or other modules. Newer generations of products typically introduce new features and / or faster processors, which provide improved computing performance. Furthermore, in the field of portable electronic devices, a reduction in the overall thickness of the computer, especially the housing, is a common goal of improving portability and customer appeal. To compensate for the smaller housing, cooling fans may include fans with reduced motor height, which may compromise motor performance. [000...
