Stator Bracket Frame Stator Insulation is Key > The fabricated steel plate statorframe consists of two or more side plates continuously welded to the wrapper plates and rectangular steel block feet to provide a rigid stator support. The strength of this frame maintains a uniform air gap under all operational stresses. Stator laminations are precision-punched from high-quality low-loss electrical sheet steel which are coated with a thermally stable insulation film (C5 coating) to minimize eddy current losses. The laminations are assem- bled in accurate alignment within the stator frame to...

Series 9000 Large Synchronous Machines - 5

High speed rotors need maximumstrength and stiffness to provide a long life. GE Motors makes its high speed rotor from a solid cylindrical forging and machines out the pole bodies and pole tips. The field wind- ings are edge wound copper strips with dimensionally stable insulation material bonded between the turns. Every turn has mechanically locked and brazed corner joints for maxi- mum strength and every other turn is larger for more efficient cooling. Medium speed machine shafts are manufactured of forged or rolled steel and machined to exact applica- tion specifications. The shaft ends...

For grinding mill applications,GE has developed a drive using two, high efficiency, synchronous motor driven pinions on one bull gear. A Quadramatic load sharing drive uses a special winding in addition to the amortisseur winding to dynami- cally alter the rotor flux. These continuous adjustments maintain the load sharing between the two pinions reducing wear and improving performance. This arrangement is generally used across all segments of industry as it requires minimal maintenance and is well suited for hazardous or contami- nated environments. The solid state components utilized are...
