Abstract

Uzwojenie klatkowe wirnika silnika indukcyjnego głębokożłobkowego ma na końcach prętów (1) wycięcia na całym obwodzie o długość osiowej l = l1 + l2, gdzie l1 oznacza długość wycięcia na odcinku obejmującym końcówkę pakietu (3), a l2 fragment wycięcia poza pakietem (3). Długość wycięcia l1 ≥ lp, gdzie lp oznacza odległość pierścienia (2) od pakietu (3), a długość l2 poza pakietem wynosi 3 ÷ 6 mm. Korzystnie wycięta jest zewnętrzna warstwa (1.1) boku każdego pręta (1) o głębokości Δ = 2 ÷ 4 mm bądź wycięta jest warstwa od strony dna żłobka każdego boku pręta (1) o głębokości Δ = 2 ÷ 4 mm lub też wycięte są warstwa zewnętrzna (1.1) i warstwa od strony dna żłobka każdego boku pręta (1) o głębokości 0,5Δ = 1 ÷ 2 mm. Innym wariantem uelastycznienia końców prętów (1) jest n obwodowych wycięć warstw wewnętrznych na każdej końcówce pręta (1) o grubości jednej szczeliny δ, gdzie n jest liczbą naturalną, a sumaryczna szczelina wycięć wynosi nδ = 2 ÷ 4 mm.The cage winding of the rotor of the deep-groove induction motor has cuts at the ends of the bars (1) around the entire circumference with an axial length of l = l1 + l2, where l1 is the length of the cut in the section including the end of the package (3), and l2 is a fragment of the cut outside the package (3). The length of the cut l1 ≥ lp, where lp is the distance of the ring (2) from the bundle (3), and the length l2 outside the bundle is 3 ÷ 6 mm. Preferably, the outer layer (1.1) of the side of each bar (1) with a depth of Δ = 2 ÷ 4 mm is cut out, or a layer from the bottom side of the groove of each side of the bar (1) with a depth of Δ = 2 ÷ 4 mm is cut out, or the outer layer is cut out (1.1) and a layer from the side of the slot bottom of each side of the bar (1) with a depth of 0.5Δ = 1 ÷ 2 mm. Another variant of making the ends of the bars (1) more flexible is n circumferential cuts of the internal layers at each end of the bar (1) with a thickness of one slot δ, where n is a natural number and the total slot of the cuts is nδ = 2 ÷ 4 mm.
