Abstract
Изобретение относитс к электромашиностроению . Целью изобретени вл етс снижение аэродинамического шума и повышение КПД, Электровентил тор содержит корпус 1 с фланцем 2 креплени , статор 4, магнитопровод 6 ротора 7 с короткозамкну- той обмоткой 8. Радиальные ребра на торце корпуса расположены несимметрично, а углы между ними выполнены не равными один другому. Это снижает аэродинамическое сопротивление и повышает КПД электровентил тора . 5 ил. The invention relates to electrical engineering. The aim of the invention is to reduce aerodynamic noise and increase efficiency, the electric fan includes a housing 1 with a flange 2 fasteners, a stator 4, a magnetic circuit 6 of the rotor 7 with a short-wound winding 8. The radial ribs at the end of the case are asymmetrical, and the angles between them are not equal one to the other. This reduces aerodynamic drag and increases the efficiency of the electric fan. 5 il.
