A data storage method includes a first client sending a first lock request for locking a first data range of a first file to a metadata server. The metadata server receives the first lock request from the first client. When the first data range of the first file is not locked, the metadata server locks the first data range of the first file and sends a first lock response to the first client to indicate that the first data range of the first file is locked by the first client.

VR glasses accessories

a stator core, a bobbin fixed on the stator core, and a plurality of windings wound on the bobbin, characterized in that the stator further comprises an elastic member with one end fixed onto the insulating frame, the other end of the elastic member is resisted against and thereby forcing the bobbin to axially position the stator.

Pump and electric motor stator thereof

A liquid pump includes a pump house with an electric motor housed therein, a pump cover connected to the pump house, an impeller housed in the pump cover and driven by the motor, and a sleeve disposed between the pump cover and the pump house. Two of the pump cover, the pump house, and the sleeve are respectively provided with an outer binding segment and an inner binding segment, the outer binding segment is made of polyphenylene sulfide mixed with glass fiber, and permeable to a laser light, the inner binding segment is capable of absorbing the laser light.

Liquid pump

A fluid pump includes a pump casing, a motor connected to the pump casing, and an impeller driven by the motor. The motor includes a housing and a stator arranged in the casing. The housing is made of a non-magnetic material. The stator includes a stator iron core and a plurality of windings wound on the stator iron core. The motor further includes a sleeve having a cylindrical main body and a flange extending radially outwards from one end of the main body and fixed to the housing. An annular space is jointly bounded by the sleeve and the housing to accommodate the stator. A part of inner surface of the housing and a part of bottom surface of the flange facing the annular space are coated with a metal coating for electromagnetic wave shielding.

Fluid pump

An electric power steering assembly includes a motor which includes a brush assembly. The brush assembly includes a brush base, a plurality of brush units and a plurality of fixing units for fixing the brush units to the brush base. The brush unit includes a brush, a guide rail and a spring. The rail includes two guiding arms, a closed end interconnecting the guiding arms and wings extending from free ends of the guiding arms. Grooves in the brush receive the guiding arms. The fixing unit includes a first fixture and a second fixture. The closed end of the guide rail engages the first fixture. The second fixture includes two columns spaced from each other. Each column defines a slot in a top end. Protrusions extend from a side of each slot to lock the wings in the slots.

Brush assembly

A electric motor has a stator and a rotor. The stator comprises a housing and a plurality of magnets fixed to an inner surface of said housing by a frame member. The magnets are embedded in the frame member. A plurality of first grooves are formed in an outside peripheral surface of the frame member, each of said first grooves extending axially from one axial surface of said frame member and having a axial length smaller than the axial height of said frame member. The housing has a plurality of first anchors formed on its inner surface, each of the first anchors engaging with a corresponding one of the first grooves.

Electric motor

An engine cooling system, comprising a fan unit, cooling pipes and a coolant tank, the coolant tank, the cooling pipes and cooling channels of the engine being connected together and forming a cooling cycle, the fan unit being used to cool the cooling pipes and the coolant therein; wherein the fan unit comprises a motor and fan blades driven by the motor, the motor comprising a stator and a rotor rotatable mounted confronting the stator; the rotor comprising a shaft, a commutator fitted to the shaft, a rotor core fitted to the shaft adjacent to the commutator, windings wound about teeth of the rotor core and electrically connected to segments of the commutator; the windings being wound by aluminum cored wire that has a electrical insulation film around its peripheral surface.
