Starting cage in the rotor of the double squirrel-cage induction motor and method for manufacturing it

摘要

a rozruchowa in wirniku engine induction dwuklatkowego is characterized by the fact that tulejki (3) are made of a material same as the rods (1), whereby the inner diameter dr tulejek (3) is equal to the diameter of the rods (1) of dp tolerance negative dr = (dp -?) and their length is equal to or less than the distance of the ring zwieraju0105cego (2) from a package (4) of the impeller.way of implementing the start-up is that after inserting the rods (1) to (5), tulejki nurseries (3) heats up to the temperature at which the inner diameter is greater than the diameter of the rod tulejki dr. dr. dp and hot tulejki (3) imposed on the rods (1),then on the rods (1) implies (2) containing rings and connects them with the rods lutem hard or that doesn't concern or weld.
