X depend on the shape and size of the rotor slot, the conductor material and the rotor current frequency. Typically K. R is in the range of 1 to 5, and K. X is in the range of 0.2 to 1. (Ref. [1] Boldea) Skin effect may not be neglected in line-start motors when assessing the starting, or breakdown torque. High Frequency Losses in Induction Motors - NASA tligh Frequency Losses in Induction Motors-Summary. might be expected since only the slot portion of the inductance is affected. Measurements on actual machines indicate that La is reduced to 0.5 to 0.3 of the normal value at fv = 20 Khz lRef.10, Part 31. www.ijiset.com Effects of Rotor Slot Area on Squirrel Cage ... In this paper, induction motor rotor slot area analyzed using two different methods. One of them, the rotor slot height is changed. Second of them, the rotor slot width is changed. Performance of the induction motor is obtained using two methods.
• Single-phase induction motor • Three-phase induction motor Single-Phase Induction Motor There are probably more single-phase AC induction motors in use today than the total of all the other types put together. It is logical that the least expensive, low-est maintenance type motor should be used most often.

The Tesla traction motor is a 4 Pole design. The IPM –AC brushless machines are synchronous motors with high poles The Switched reluctance motor is a synchronous machine with high poles The Reluctance Synchronous motor is sort of in between, although it is a synchronous machine the pole number can be 4, 6 or 8 for traction.
Abstract: This paper proposes optimal design method of stator slot for three-phase cage induction motor fed by six-step inverter output voltage by using proposed analysis method. The finite-element method (FEM) on one phase band stator periodic condition is coupled with harmonic equivalent circuit. Induction Motor Design (3-Phase) Maximum flux density in stator tooth should not exceed 1.8T; otherwise iron losses and magnetizing current will be abnormally high. (So if flux density >1.8T, change slot dimensions) Mean flux density in the stator tooth is calculated at of tooth height from the narrow end of the stator tooth. Optimal Design of Induction Motor Using - AMSE Second, by acting on the motor design, which means increasing the volume of the active material (Iron and Copper), using longer machines in order to keep the same slot design, selecting lower current density and a higher copper slot fill-factor, choosing new material with high magnetic Winding type influence on efficiency of an induction motor
4. MOTOR DESIGN METHODOLOGY The design methodology of the three phase induction motor can be divided into the following processes: 1. Main dimension calculations (Stator OD, ID and stack length) 2. Stator and rotor slot dimensioning 3. Winding layout 4. Electric and magnetic loading calculation 5. Equivalent circuit calculation 6. Efficiency ...
