Abstract: A current vector controlled synchronous reluctance motor and control method thereof, wherein the motor has a coil on each of the teeth. The coils form a U-phase winding, a V-phase winding and a W-phase winding. The phase windings receive a balanced three-phase current vector to induce closed magnetic field lines, such that the coils induce same magnetic poles adjacent to the rotor unit. Two short magnetic routes are formed along three adjacent teeth and the rotor unit. The efficiency of the reluctance motor is high.

Abstract: A fan includes a fan frame having an upright barrel, a fan blade unit having a fan hub with radial blades, and a driving module formed of a stator, an axle bearing, a core shaft and a rotor for causing rotation of the fan hub with the blades relative to the stator. The stator has a collar affixed to the barrel of the fan frame, radial ribs extending from and spaced around the periphery of the collar, and three-dimensional wings respectively connected to the free ends of the radial ribs each three-dimensional wings having a smoothly arched and radially and axially extending outer surface.
