A brushless motor includes a stator as an armature where a plurality of coils is housed and a rotor as a magnetic exciter having a permanent magnet, wherein an end portion of the coil housed in a slot of a stator stack is inserted into a wire binding board having a wire binding pattern of the coil, the end portion of the coil is soldered to a land of the wire binding board, and the wire binding board and a circuit board are electrically conducted to each other through an connecting terminal.

Brushless motor

Provided is a brushless motor insulator capable of improving workability relating to the winding of electric wires by a simple configuration. An insulatorincludes a main body portionand a mooring portion. The main body portionincludes plural wiring portionsradially provided so that electric wiresare held while being wound on the wiring portions. The mooring portionis disposed in the inner periphery or the outer periphery of the main body portionand moors ends of winding start portions or winding end portions of the electric wiresof the wiring portions

Brushless motor insulator, brushless motor stator, brushless motor, and method of manufacturing brushless motor

Four tapered portions are formed on an end portion of an inner wall surface of an air channel at four locations corresponding to four corners of the profile of a surface of a housing where a suction port is formed. The four tapered portions are each inclined outwardly in a radial direction of a rotary shaft from a discharge port side toward the suction port side and extending in a rotational direction of an impeller. The tapered portions each include a main portion which is shaped such that an angle formed between the main portion and an axis of the rotary shaft gradually becomes smaller from one end of the main portion located rearward as viewed in the rotational direction of the impeller toward the other end of the main portion located forward as viewed in the rotational direction of the impeller.

Fan with reduced noise

A fan system with enhanced air flow-static pressure characteristics and reduced fan noise compared to the related art is provided. The number of duct blades of a duct is the same as the number of stationary blades of an axial flow fan located in front of the duct, and the duct blades correspond to the stationary blades respectively. An end surface of a rear end portion of each stationary blade and an end surface of a front portion of a duct blade corresponding to the stationary blade have the same shape, and they align together and contact each other to form one composite stationary blade, with a discharge port of each axial flow fan communicating with an inlet port of a duct housing located behind the axial flow fan.
