Traditional Design of Cage Rotor Induction Motors Traditional Design of Cage Rotor Induction Motors Ronald G. Harley and Yao Duan Georgia Institute of Technology November, 2009 . Rating considerations Dimensions of a machine depend on • Torque at a specific speed • How intensively the magnetic circuit is used. • How intensively the electric circuit is used • The type of enclosure • Type of cooling • The duty cycle of the load ... Optimization of Motor Rotor: Slot Shape, Frame Size, Rotor ... Shown in Fig. 2 are three different possible slot shapes. On the left is the shape used in the original cast aluminum rotor. It has a characteristic tapered shape so that the teeth between rotor bars are of uniform section.
A poly phase induction motor consists of two major parts, the stator and rotor When stator isThis field produces an EMF in the rotor winding by mutual induction principle, which in turn circulatesDesign of stator core involves shape of slots, no. of slots , dimensions of teeth and depth of slot.
Shaded Pole Induction Motors - Working and Construction Construction of Shaded Pole Induction Motor. Stator. Rotor.The short-circuited copper coil described above is placed in this slot. So we can call this part as the shaded part and other parts of the pole as unshaded part.The rotor of shaded pole induction motors is Squirrel Cage type rotor. Ac-induction-motor rotor lamination having rotor... An AC-induction-motor rotor lamination has a longitudinal axis and circumferentially spaced apart and closed rotor slots. Each rotor slot includes first through fifth corners, a straight slot base, straight first and second slot sides, and first and second curved sides. The slot base extends from the first corner...

Three-Phase Wound-Rotor Induction Motor CONSTRUCTION A three-phase, wound-rotor induction motor consists of a stator core with a three-phase winding, a wound rotor with slip rings, brushes and brush holders, and two end shields to house the bearings that support the rotor shaft. 3.
In Squirrel cage rotor, slots in lamination or rotor core is not made parallel to the rotor shaft. A slight angle is maintained due to some advantages. This is called the rotor Skew. Rotor of an Induction Motor skewed due to following reason… The Impact of the Rotor Slot Number on the Behaviour of… Then, six motors with different rotor slot numbers are simulated and studied with FEM.The induction motor design is strongly connected to the power electronics design, since different motor configurations strongly affect its electromagnetic characteristics.

EXTERNAL ROTOR SHAPEEXTERNAL ROTOR SHAPE ... method is a useful way to determine the rotor shape. Fig. 2. Stator and rotor structure. 3. EXPERIMANTAL RESULTS The most important characteristic for an induction motor is the mechanical one. This was obtained after laboratory tests for different supply voltage (line voltage). The achieved results are presented in Fig. 3. Fig. 3. Induction Motors Notes - ssmengg.edu.in Stator of an induction motor consists of stator core and stator slots. Stator slots: in general two types of stator slots are employed in induction motors viz, open clots and semiclosed slots. Operating performance of the induction motors depends upon the shape of the slots and hence it is important to select suitable slot for the stator slots.
