High Voltage Motor - 2

In conjunction with a world renown consultant company, WEG developed its three phase induction motors which allow easy maintenance and high performance level. Divided in two different lines, H Line (High Performance) motors have been designed in such a way to withstand the most demanding applications and are regarded as both a reliable and low maintenance cost solution under such conditions. M Line (Master) motors can be applied on a wide variety of applications with different operational requirements. In addition the M Line can be easily modified to match existing motors. M Line and H Line...

Frame Manufactured either with welded steel plates or cast iron, the frame is motor structural component that accommodates, supports and protects the active magnetic part of the motor. Its rugged construction offers excellent mechanical strengthen to the motor along with low vibration levels. Stator Regarded as the static magnetic part of the motor, the stator consists of a steel laminated core. The coils forming the stator winding are fitted into the lamination core slots. The stator core is mounted directly on the motor frame. Winding The winding process supplied by WEG is specially...
