Abstract: An electric fuel pump includes a housing having an oil inlet and an oil outlet, an impeller, a stator unit mounted in the housing and including a stator and a starter terminal set connected to the stator, a packaging adhesive encapsulating the stator and the starter terminal set to create an oil guide passage in communication between the oil inlet and the oil outlet, and a rotor unit mounted in the housing and including a rotor rotatably mounted in the stator and a rotating shaft mounted in the rotor and connected with the impeller. When the stator unit is electrically conducted, the rotor unit drives the impeller to draw a fuel oil into the oil guide passage. When the fuel oil goes through the oil guide passage, the stator and the starter terminal set are well protected by the packaging adhesive and prohibited from contacting the fuel oil.

Abstract: A speed reducer used in a server is disclosed to include a first planetary gear set, a planet gear carrier, an internal gear surrounding the first planetary gear set, and an output gear. The first planet gear includes a first sun gear mounted on the motor output shaft, at least one first planet gear pivotally coupled at the first planet gear carrier and meshed with the first sun gear and the internal gear for driving the first planet gear carrier and the output gear to rotate. Thus, the first planetary gear set reduces the revolving speed of the rotary driving force outputted by the motor output shaft, and effectively transfer the rotary driving force to the output gear, achieving the advantages of low backlash and long service life, reducing power transfer loss, increasing server output torque, and providing high speed ratio, high design flexibility and high assembly yields.

Abstract: A modularized servo case includes a hollow first barrel and a hollow second barrel, each of which has a lower opening at a bottom end thereof. The first barrel and the second barrel have a first connecting portion and a second connecting portion disposed on outer surfaces thereof, respectively.
