Miniature heat-dissipating fan with improved hall element and circuit board arrangement

A miniature heat-dissipating fan, comprising:

• a stator seat comprising a winding wound therearound, an axle tube disposed in a center portion of said stator seat, said axle tube for rotatably receiving a rotor shaft, and an upper polar plate and a lower polar plate respectively mounted on said axle tube on upper and lower surfaces of said winding, said lower polar plate having an outer portion which extends radially past said winding;
• a circuit board mounted around said axle tube and below said lower polar plate, said circuit board having a straight edge and a plurality of leads, each of said leads having an edge leading to the straight edge;
• and
• a Hall element having a main body and a plurality of pins, each of said pins being connected to a respective lead of said plurality of leads of said circuit board, wherein:
• said plurality of pins of said Hall element are oriented along and in contact with the straight edge of said circuit board, and
• the main body of said Hall element is disposed in a space beside the outer portion of said lower polar plate.
