A fan apparatus includes a casing and a fan unit. The casing is a hollow member having an inlet and an outlet. The fan unit has an inlet and an outlet, and includes a plurality of axial fans. The fan unit is disposed on the inside of the casing, and the inlet of the fan unit is disposed in the vicinity of the inlet of the casing. The position of the fan unit within the casing can be varied in order to alter the air flow and static pressure of the air discharged by the fan apparatus.

Fan apparatus

A fan apparatus includes a fan section having a hollow housing with an inlet and an outlet, and a hollow duct section disposed on the outlet side of the fan section. The housing and the duct section are coupled by a coupling member.

A method to hook a magnet wire extracted from a coil A stator coreincludes a core backof a substantially annular shape. At a radially outer end portion of the core backfour teethare arranged radially. At the teeth, a coilis formed by winding a magnet wirevia an insulator. A first insulatorconfiguring a lower half of the insulatorincludes a first core back insulating portion, 1 first teeth insulating portion, and a first cylindrical portion. A hook portionis formed at the first core back insulating portionat radially outer side, and between the teeth. The magnet wireextracted from the coilis hooked on the hook portion. The magnet wirehooked on the hook portionis lead the magnet wirearound the hook portionas a base, and is soldered to a landformed above a circuit board
