Brushless motors for portable information equipment that can be simultaneously reflow-soldered to a substrate and efficiently and densely mounted thereon in such a way that the coupled portion between the motor and the substrate has a high impact resistance, thereby providing small and reliable portable information equipment having a high productivity. The brushless motor including a housing having a bottom surface, a side surface, and a top surface, the bottom surface being located adjacent and opposite to a substrate of equipment; a plurality of lands ( ) on the bottom surface that can be mechanically or electrically joined with the substrate of the equipment; a stator ( ), a bearing device ( ), and a rotor ( ) inside said housing, the stator ( ) having a stator core ( ) and a coil ( ) wound around the stator core ( ), the rotor ( ) having a magnet ( ) and being supported by the bearing device ( ) so as to rotatably surround the periphery of the stator ( ), the rotor ( ) further including a circular weight ( ).
