All ot' the bars of this squirrel-cage rotor are being joined simultaneously i-. to one end ring by the 'X'esringhouse high-frequency brazing process. The end ring is heated by high-frequency currents induced by the coil on which it rests, and conduction carries heat to the bars. This process inspects itself . . . the red-hot bars are clear proof of positive joints. A big extra in large motors .. Westinghouse special brazing process f boosts rotor reliability, slashes maintenance High-frequency brazing eliminates rotor joint failure ; ; . proved on over 1500 motors operating up to five years without a single failure I.S'rThis is a large standard type CSF gr: drip-proof motor. It can easily modified to meet any special 'ji; mechanical-drive requirement. & ?:= w: This technique licks the biggest single trouble spot in rotors of large motors. Bars are brazed to the end rings --and connections are tested at the same time. It is the only way to get solid, indestructible joints . . . your positive * assurance of reliable operation under the toughest conditions. * You get many important extras in Westinghouse large motors. Therma- * lastic insulation, for example, gives over 20% increase in dielectric strength, 10-to-l increase io voltage endurance--withstands moisture, dust and -' corrosive atmospheres. ' Both of these features have been extensively proved in service. They give * you a motor far superior in performance and long life . . . the closest you can come to a completely maintenance-free mechanical drive.
