1,10 machines, and especially tqlthe structure and method of forming a squirrel cage rotor.
The mainobjects of the invention are to provide a squirrel cage member of improved form adapted for high electrical elliciency, thorough ventilation, good starting characteristics and convenience in manufacture; and to provide an improved method. of forming such a devic .A n illustrative embodiment 'of this invention is shown in the accompanying draw? ings, in which- Fig. l is an end view of a squirrel cage rotor.
Fig. 2 is a section on the line 2-2 of Fig. n
Fig. 3 is an enlarged cross section through one of the Squirrel cage hars.
Fig. a is a sectionsimilar to Fig. 3 before platine.
In the construction shown in the drawings, the laminated core l is clamped rigidly together by any approved means, for. instance as indicated at 2, and mounted on a shaft, as usual for such devices.- On said 8i core is a ventilated squirrel cage Wi ding 3 comprising end rings 4 and connecting hars 5, said bars being disposed in the openings ti of the slotted core 1. Said Winding 3 is in the `form of an electrodeposit of -copper applied to an intermediate coating of zinc indicated at?.
By this means a compound squirreleage structure is provided in which a metal having substantial resistance is disposed against 45 the core and a. good conductor of much greater thicknessA is secured thereto and spaced from the core by the higher resistance metal. These metals, it is to be understood, are not necessarily limited to 'Zinc and copper. The hot metal dip prepares the core for ready deposit of the plating.
The double walled lhars 5 are hollow throughout their length and are thereby adapted tornei... lient ventilation. The com,
