Induction motor rotor slot shape

Wound Rotor - TECO-Westinghouse motor life is ensured with the use of external resistor banks or liquid rheostats that dissipate heat build-up generated during motor start-up. What makes the wound rotor motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor coils is used to accept external impedances. An optimum design of rotor slot shape of induction motor for ...

There were many attempts to design the rotor bar shape to increase the starting torque in squirrel cage induction motor, and it is well known that deep slot of rotor bar increases the starting torque. Effects of the Geometry of the Rotor Slots on the magnitude whenthe motor possesses different geometrical rotor-slot shapes.The cross sectional areas of two typical semi-closedslotshapes (rectangular andro undshapes) are kept equally constant according to the IEEE induction motors, Proc. the 24th IASTED International Conference on Modelling, Identification, andControl (MIC 2005), Austria, Stator Slot Shape Design Of Induction Motors For Iron Loss Stator Slot Shape Design Of Induction Motors For Iron Loss Reduction; Similarly, it can be observed that mode number 1 is usps mail slot size only excited when the stator slot shape design of induction motors for iron loss reduction rotor slot number is odd, which is clear from Table I.. 14 and 15, assuming stator slot shape design of induction motors for iron loss reduction copper mummy slot

Shape Design of a Rotor Bar for Improving Starting Torque And Running Efficiency in Squirrel Cage Induction Motor Ha Jeong Lee1, Sang Hyeon Im1 and Gwan Soo Park1 1School of Electrical and Computer Engineering, Pusan National University, Busan 46241, South Korea gspark@pusan.ac.kr This paper presents a design of rotor bar to improve the starting torque. Squirrel-cage rotor - Wikipedia A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor.It consists of a cylinder of steel laminations, with aluminum or copper conductors embedded in its surface. In operation, the non-rotating stator winding is connected to an alternating current power source; the alternating current in the stator produces a rotating magnetic field. Dynamic Modelling of Induction Motor Squirrel Cage for Dynamic Modelling of Induction Motor Squirrel Cage for Different and speed) of the series of motors with different shapes of rotor bars is carried out and compared with a conventional model (without skin effect) in order to see the influence of this phenomenon on the ... Rotor slot … 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.

The rotor is cylindrical in shape and has slots all over its periphery. The slots are not made parallel to each other but are bit skewed as the skewing prevents magnetic locking of stator and rotor teeth and makes the working of induction motor more smooth and quieter. The squirrel cage rotor consists of...
