Cage rotor for low output async machines - has short-circuit rod with ends bent to lie inside sleeve on short-circuit plate or plate packet

摘要

The rotor has short-circuit rods (3) arranged in passages of the plate packet. A short-circuit plate (2) is provided at the two ends of the plate packet. The ends of the short circuit rods (3) extending out from the plate packet (1) are electrically short circuited and are mechanically connected. . The extending ends (5) of the short circuit rods (3) are bent into a hook shape such that they lie inside a sleeve on the short circuit plates (2) and/or on the plate packet (1). The sleeve extends axially from the circumference of the plate packet (1). The outer diameter of the short circuit plates (2) preferably, at most, correspond to the inner edge distance of diametrically opposing short circuit rods (3). The ends (5) of the rods (3) are preferably bent over the edge of the short circuit plates (2).
