A shield sheet comprises a collar magnetic sheet and a center magnetic sheet. The collar magnetic sheet is provided with a hole adapted to the center magnetic sheet. The center magnetic sheet has one end fixed in the hole and the other end protruding out of the collar magnetic sheet. The collar magnetic sheet comprises at least one first magnetic permeable layer, which is a nanocrystal strip, an amorphous strip or a metallic soft magnetic strip. The center magnetic sheet comprises at least two second magnetic permeable layers stacked one on another, which are fragmented nanocrystal strips, fragmented amorphous strips or fragmented metallic soft magnetic strips. Fewer nanocrystal strips are stacked for the collar magnetic sheet in the shield sheet of the invention, facilitating the miniaturization of the shield sheet and increasing charging efficiency.

A brushless motor includes a stator having stator core and winding teeth evenly distributed on the stator core; and a rotor rotatably disposed within the stator with the winding teeth facing the rotor, where the rotor has a rotor core and magnets evenly distributed around the rotor core. A first symmetry axis is defined passing through a center of a one of the magnets to a center of the rotor, and a second symmetry axis is defined passing between adjacent magnets to the center of the rotor. A first distance between the outer surface of the rotor to a surface of a winding tooth when the first axis is aligned with the winding tooth is smaller than a second distance between the outer surface of the rotor to the surface of the winding tooth when the second axis is aligned with the winding tooth.

Combination structure between stator and rotor in a brushless motor

A brushless motor includes a stator core having a plurality of tooth portions; a lower insulating bobbin connected to a lower face of the stator core, the lower insulating bobbin having a plurality of lower slot insulation portions each corresponding to a respective tooth portion; and an upper insulating bobbin connected to an upper face of the stator core, the upper insulating bobbin having a plurality of upper slot insulation portions each corresponding to a respective tooth portions such that the upper slot insulation portions, the tooth portions, and the lower slot insulation portions define a plurality of coil wound portions. The plurality of coil wound portions includes at least one group of coil wound portions with each group having first to sixth coil wound portions. All of the coil wound portions of all groups are wound by a single lead wire.

Stator with insulating bobbin in a brushless motor

A brushless motor includes a stator having a stator core; and an upper insulating bobbin connected to an upper face of the stator core, an upper surface of the upper insulating bobbin having a plurality of terminal fixing blocks and a plurality of wire through blocks, each terminal fixing block having a wire-through notch for positioning a wire and a terminal socket electrically connected with the wire. A first angle between a wire slot of each terminal fixing block and a radial direction of the upper insulating block is 50&#xb0;-130&#xb0;, and a second angle between a terminal socket of each terminal fixing block and a circumference direction of the upper bobbin is 50&#xb0;-130&#xb0;.

Brushless motor having terminal fixing blocks

A brushless motor includes a printed circuit board having a plurality of locating holes therethrough; and an upper insulating bobbin including a plurality of locating bosses distributed along a circumference direction of an upper surface of the upper insulating bobbin. Each locating boss has a locating column projecting from a top surface thereof such that each locating column is inserted into a respective locating hole.
