Induction Motors Horizontal and Vertical - 1

Induction Motors Horizontal and Vertical Induction Motors Horizontal and Vertical Electric Machinery (EM) induction motors have been specifically designed and manufactured for the most severe Converteam Electric Machinery (EM) induction motors have been industrial applications, such as heavy duty fans, pumps, refiners, specifically designed and manufactured for the most severe compressors, crushers and grinding mill drives. industrial applications, such as heavy duty fans, pumps, refiners, compressors, crushers and grinding mill drives. • Rotor cage bars • Rotor cage bars The oxygen-free copper alloy cage bars The oxygen-free copper alloy cage bars are silver brazed into special milled are silver brazed into special milled pocket joints in the circular end rings. pocket joints in the circular end rings. The end ring joints provide greater The end ring joints provide greater contact and locking than other methods contact and locking than other methods of attaching end rings. Each joint is of attaching end rings. Each joint is ultrasonically inspected to obtain the ultrasonically inspected to obtain the highest quality. The ultrasonic test for highest quality. The ultrasonic test for thisapplication was developed by EM his application was developed by EM engineers. This permits higher heat engineers. This permits higher heat absorption capacity for starting high absorption capacity for starting high inertia loads. inertia loads. • Rotor laminations • Low loss, non-segmental rotor Rotor laminations laminations are tightly anchored to the Low loss, non-segmental rotor shaft.
