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. Design of Stator - Induction Motors - brainkart.com
the field effects of stator-rotor slot combinations are the common causes for high magnetic noise in induction motors [3], [4], [5]. Finley [4] discussed various techniques to decrease the magnetic noise in electric motors. A good literature review on this topic could be found in [7]. This paper presents a theoretical model for the prediction

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. Designing of Three Phase Squirrel Cage Induction Motor for The manual design of induction motor is the combination of lengthy calculations and special attention. [16] And in order to get acceptable results redesign procedure is sometimes needed. The design features of an induction motor are classified as constructional wise and … Optimal design of electric motors - dis.uniroma1.it 0 : design infeasible 1 : design feasible Performances/features Manufacturing cost Operating cost Rated efficiency Power factor at rated load Starting current Starting torque Breakdown torque Stator slot fullness Stator winding temperature Rotor bars temperature Induction in the stator and rotor teeth Rated slip Rated power
Design and Development of Three Stator 343 power consumed due to eddy currents, copper losses and poor power factor are considerably reduced [11]. The efficiency of an induction motors ranges between 0.75 and 22 kW can be improved by means of die cast copper instead of aluminium cage rotor with premium steel core [12].
Design of Electrical Machines Questions and Answers – Single Phase Induction Motor Construction.Answer: a Explanation: The rotor consists of a block of slotted laminations. The slots form a series of tunnels which are filled with aluminium in its molten state. Traditional Design of Cage Rotor Induction Motors - ppt… 28 Traditional induction motor design steps (continued) 25. Calculate motor performance data from equivalent circuit and compare with results from FEA: Slip at full load Starting current and torque Torque-speed curve (if not acceptable then change rotor slot geometry and return to step 12)... Construction of Induction Motor - Circuit Globe The three phase induction motor is a preferable type of motor. It is mostly used in industrial drives because it is very reasonable and vigorous, economical and reliable. It is also called asynchronous motor because it does not run at a synchronous speed.
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 ... Optimal stator slot design of inverter-fed induction motor ...
