FIELD: manufacture of pumps and fans, namely centrifugal blowers used for transferring liquid and gas from one reservoir to another. SUBSTANCE: centrifugal blower has housing with partition dividing the blower into drive section and flow-through section with inlet and delivery branch pipes. Stator and magnetic circuit are arranged in drive section. Impeller rigidly connected with circular disk rotor of multipole magnetizing and magnetic circuit are arranged in flow-through section. Rotor and stator are located between two magnetic circuits. Rotor and magnetic circuits are made in form of disks. Diameter of disks of rotor and magnetic circuits and diameter of outer boundary of active wire bundles of stator winding which has form of circle are equal to diameter of impeller. Axes of all disks are coaxial relative to axis of impeller. EFFECT: enhanced reliability. 2 cl, 4 dwg
