Optimization of Motor Rotor: Slot Shape, Frame Size, Rotor ... Optimization of Motor Rotor: Slot Shape, Frame Size, Rotor Diameter SLOT SHAPE Designing Squirrel Cage Rotor Slots with High Conductivity I. INTRODUCTION: There has been, in recent years, an effort to make cast copper rotors for industrial use induction motors. The objective is to make motors more efficient because of the higher conductivity of ... Optimization of the geometry of closed rotor slots for ... Furthermore, optimization of the geometry of the rotor slot for cage induction motors has led to reduced harmonic losses [6] and static airgap eccentricity [7]. The work of [8] discussed the ... On the Influence of Stator Slot shape on the Energy ... Approach: A new stator slot shape is proposed based on the results obtained from the iterations with Rotational Machine Expert (RMxprt) software and the performance is compared with that of the existing stator slot shape, for a 3-phase, 5 hp, 380 V, 2-pole motor The motor with both the An optimum design of rotor slot shape of induction motor ...
Rotor design of Induction Motor
Rotor As described earlier, rotor of a 3 phase induction motor can be of either two types, squirrel cage rotor andMost of the induction motors (upto 90%) are of squirrel cage type. Squirrel cage type rotor has very simple andRotor slots are slightly skewed to achieve following advantages
An optimum design of rotor slot shape of induction motor
Rotor Slot Shape Optimization of an Induction Machine; Ing. This thesis is dealing with optimization by using artificial intelligence of an induction machine rotor slot. The one optimized is commonly manufactured induction motor with simple deep bar rotor. Double Cage Induction Motor - Polytechnic Hub In case of 3Ø squirrel cage motor has low starting torque. This is due to the low Rotor Resistance. Then, the starting torque with increase but at the same Electromagnetic Fields in Electrical Engineering - Knihy Google

Dynamic Modelling of Induction Motor Squirrel Cage for ... Dynamic Modelling of Induction Motor Squirrel Cage for Different Shapes of Rotor Deep Bars with Estimation of the Skin Effect Zakari Maddi* and Djamal Aouzellag Abstract—This paper presents a dynamic modelling of a series of induction motors (IM) squirrel cage with different shapes of rotor deep bars taking into account the skin effect. Optimal Shape Design of Rotor Slot in Squirrel-Cage ... Optimal Shape Design of Rotor Slot in Squirrel-Cage Induction Motor Considering Torque Characteristics Abstract: Induction motors are widely used in various industrial applications with different torque-speed characteristics. Since the configuration of the rotor slot has a great impact on the electromagnetic torque-speed characteristics, a ... Effects of the Geometry of the Rotor Slots on the ... rotor slot shapes of equal slot areas, i.e. i) rectangular shape and ii) round shape, are challengedby observing the mechanical vibration around the stator inner perimeter,the round case gives less vibrationof 4.8% thanthe rectangular case does. We can conclude that when the mechanical vibrationis takenintoaccount inthe
