236 ALTERNATING-CURRENT MACHINERY 225 field sets up induced currents in the short-circuited frames or bars ofthe damper, and these currents react on the magnetic field so as tooppose the shifting of the flux and thereby dampen the hunting oscil-lations. The electrical effect of the dampers is… … Fig. 200. Rotor of a Synchronous Motor Provided with Squirrel-Cage Form of Damper Torque and Power Output. A given synchronous motor operat-ing with given applied voltage is capable of developing a definitemaximum torque, or of delivering a definite maximum amount ofpower. An attempt to take more…
