The utility model relates to an electronic auto-controlled energy-saving one-way blowing machine, belonging to a blowing machine. The electronic auto-controlled energy-saving one-way blowing machine is the improvement of a one-way blowing machine composed of a casing, a wind wheel, a cage rotor, a main shaft, and a stator winding. Two sets of starting windings are opened. A time relay in an electric control box arranged on the casing of the blowing machine is used for controlling the conducting and the breaking of the starting windings. Each opened starting winding can be respectively connected with an indicating lamp. When the blowing machine is started, the two starting windings in a short-circuit condition, which enables the blowing machine to positively rotate; after the blowing machine is started, the time relay enables the two starting windings to break or be in a loading (the indicating lamp) condition and the two starting windings not to heat, so the utility model has the conspicuous effect that saves power and extends the lifetime of the blowing machine.
