The performance of a 3-phase, 4-pole, 24000 rpm, axially slitted and radially grooved high-speed ... more The performance of a 3-phase, 4-pole, 24000 rpm, axially slitted and radially grooved high-speed solid rotor induction motor (SRIM) with copper end-rings is studied and analyzed numerically, using a 2D FEM tool. The prototype motor is constructed and tested. The FEM simulation results are compared with the measured ones.

The effect of the radial rotor surface grooves on rotor losses, in the case of a 3-phase, 4-pole,... more The effect of the radial rotor surface grooves on rotor losses, in the case of a 3-phase, 4-pole, 24000 rpm, axially slitted solid rotor induction motor has been studied numerically and experimentally. The study shows that through radial grooving of the rotor outer surface and thereby cutting the path for high frequency rotor harmonic currents results in considerable reduction of

In high-speed applications the mechanical strength of a solid rotor induction motor is recognized... more In high-speed applications the mechanical strength of a solid rotor induction motor is recognized as a significant benefit. The performances of a 4-pole and a 2-pole solid-rotor induction machines for 29100 min-1 are analyzed numerically and compared with the measured performance of a permanent magnet synchronous motor of the same active volume. The 3-phase, 4-pole, axially slitted prototype solid rotor
