Abstract
A fan motor includes a printed circuit board (200), an IC (100) and an insulating frame (50) mounted on the printed circuit board. The insulating frame includes an annular main body (44) with a number of arms (11) extending radially from an outer-periphery thereof, and a retaining member (14) formed thereon corresponding to the IC. The retaining member includes a pressing portion (12) pressing the IC to prevent slant thereof.
Claims13
A fan motor comprising:
- a printed circuit board;
- an IC mounted on the printed circuit board;
- and
- an insulating frame mounted on the printed circuit board, the insulating frame comprising:
- a main body comprising a plurality of arms radially extending therefrom for windings wound therearound, and
- a retaining member extending radially and outwardly from the main body corresponding to the IC, the retaining member being located between two neighboring ones of the arms and comprising a pressing portion pressing the IC to prevent slant of the IC.

A fan motor comprising:
- a printed circuit board defines a plurality of mounting holes therein;
- an IC mounted on the printed circuit board;
- and
- a stator assembly comprising an insulating frame having a main body with a plurality of mounting flanges extending toward the printed circuit board, and a retaining member engaging with the IC to prevent slant of the IC with respect to the printed circuit board, a plurality of mounting pins being formed on the stator assembly;
- wherein
- the retaining member forms at least one of the mounting pins engaging into the mounting holes to secure the insulating frame to the printed circuit board, and wherein the retaining member extends from the main body and is located between two neighboring ones of the mounting flanges.
3 more elements
A fan motor comprising:
- an electronic component located in said fan motor, one side of said electronic component having an electrical connection;
- and
- a frame located in said fan motor next to said electronic component, and having at least one portion protruding radially and outwardly from said frame and reachable to another side of the electronic component other than said one side having said electrical connection so as to retain said electronic component in a predetermined position of said fan motor;
- wherein said electronic component is mounted on a printed circuit board to establish said electrical connection and said printed circuit board is engagable with said frame;
- and
- wherein said at least one portion of said frame forms a plurality of mounting pins, and the printed circuit board defines a plurality of mounting holes receiving the mounting pins therein to secure the frame thereon.
