High-speed, 8 MW, solid-rotor induction motor for gas compression

The suitability of solid rotor technology in a high power output hermetic natural gas compression application was studied. Two new solid-rotor designs for an 8 MW, 6.6 kV, 12000 min
^-1
and a 10 MW machine were done and the motors successfully tested. The former carries a purely solid, slitted rotor and the latter has a copper cage manufactured of copper bars inserted in solid rotor core drill bores.
