ROTOR SLOT PERMEANCE HARMONICS UNDER DISTORTED AIR-GAP ... ROTOR SLOT PERMEANCE HARMONICS UNDER DISTORTED AIR-GAP FLUX WAVEFORM FOR CAGE INDUCTION MOTOR Prepared by S.P. Liou, J.S. Hsu, W.F. Weldon Presented at The IEEE Power Engineering Society 1991 Summer Meeting San Diego, CA July 28-August 1, 1991 Publication PR-143 Center for Electromechanics The University of Texas at Austin Advantage of Skewed Stator Slots in the Rotor of Induction ... Advantage of Skewed Stator Slots in the Rotor of Induction Motors? In the Induction motor design, the rotor slots are purposely made with a slight skew arrangement. Construction of squirrel cage ... The Impact of the Rotor Slot Number on the Behaviour of ... The impact of the rotor slot number selection on the induction motors is investigated. Firstly, analytical equations will reveal the spatial harmonic index of the air gap magnetic flux density, connected to the geometrical features and the saturation of the induction motor. Then, six motors with different rotor slot numbers are simulated and studied with FEM.

INFLUENCE OF STATOR SLOT-SHAPE ON THE ENERGY CONSERVATION ASSOCIATED WITH THE SUBMERSIBLE INDUCTION MOTORS 3.1 INTRODUCTION The electric submersible-pump unit consists of a pump, powered by a medium-voltage three-phase induction motor. The power transmission system is integrated with riser-pipes. Pipe stacks are flanged together, and
conductivity of cast copper in rotors of induction motors. Deep bar and multiple cage effects are useful in design of such machines. It is shown that a useful understanding of how different slot shapes work may be developed through the use of frequency response curves that describe rotor slot impedance as a function of rotor frequency.

Optimal Design of Rotor Slot Geometry of Squirrel-Cage ... Optimal Design of Rotor Slot Geometry of Squirrel- Cage Type Induction Motors V. Fireteanu*, T. Tudorache* and O.A. Turcanu* * POLITEHNICA University of Bucharest /Electrical Eng. Dept., EPM_NM Lab., Bucharest, Romania Abstract—This paper deals with the optimal design of squirrel- cage rotor slots and copper bars of high power induction motors III. Why is an induction motor design in a skewed shape? - Quora Why is an induction motor design in a skewed shape? Update Cancel. ... The rotor of 3 phase induction motor is skewed to avoid Cogging which does not allow motor to rotate. ... there is slight angle between rotor and stator magnetic field due to which each rotor slot at a time comes under two stator slots. Thus the phenomenon of Cogging is avoided. Induction Motor -Basics, Single Phase and Three Phase ... Induction motor works on the principle of induction where electro-magnetic field is induced into the rotor when rotating magnetic field of stator cuts the stationary rotor. Induction machines are by far the most common type of motor used in industrial, commercial or residential settings.
