Semi-closed slots or totally closed slots are used in induction.

The slot leakage is very much dependent upon the shape of slots. It is larger in semi-closed slots (Fig. 5.46(a)) used in induction machines, because of narrow (low reluctance) slot opening, compared to open slots (Fig. 5.46(b)) used in synchronous and dc machines. Slots in Induction motor: The speed of the induction motor is inversely proportional to the load torque. In semi-closed and closed slots, the air gap between the stator and rotor is small as compared to open slots.As the air gap is small, the requirement of magnetizing current to establish the flux in the air gap is less.

Open circuit stator resistance short-circuit slip ⇒ If there is a break in a 220/110V auto-transformer in the winding which is common to both hv as well as lv sides, then the output voltage on the iv side will be 110 V 220 V zero 110√ 2 V ⇒ A 3-phase slip-ring induction motor having negligible stator impedance drives a constant torque load.

A characteristics calculation of induction motors is rather complicated in closed-slot induction motors. The inductance of a closed-slot bridge, that is, its leakage reactance has been problematic due to saturation of a magnetic steel sheet at a bridge. In this paper, the inductancecharacteristics of a closed-slot induction motor are studied.

A novel traction AC motor is proposed by grouping magnets and coils in the stator design with aluminium as substantial for the housing of stator and end ring. The stator back iron is designed with silicon steel. As a result, the magnet can provide more repulsion when revolving the rotor, lowering the input side current. The configuration of the motor was changed to increase its effectiveness.

Answer (1 of 2): Reactance, what is it? It is the flux that links with either stator or rotor but does not link with both. It is useless as it does not produce any electromechanical torque. Google Image Result Look at magnetic circuit of stator (image is for rotor but basic funda is same). If.

In case of specially designed rotor the peripheral speed can be 60 m/s. Design of Stator 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. Hence these types of slots are rarely used in 3Φ induction motors. (ii) Semiclosed slots: In such type of slots, slot opening is much smaller than the width of the slot as shown in Fig 10 and Fig 11. Hence in this type of slots assembly of windings is more difficult and takes more time compared to open slots and hence it is costlier.

Question is ⇒ Semiclosed or totally closed slots are used in induction.

INDUCTION MOTORS. 1. Define slot space factor. The slot space factor is the ratio of conductor area per slot and slot area. It gives an indication of the space occupied by the conductors and the space available for insulation. The slot space factor for induction motor varies from 0.25 to. 0.4. 2. Define distribution factor or breadth factor.. 3-Phase Induction Motors EE 340. Where does the power go? • The electric energy generated purchased by consumers for different needs.

PDF How an Induction Motor Works by Equations (and Physics).

The rotor winding 24 is unique, in machines of this class, in having wide-open slots 22, so that each rotor winding-conductor or bar, with its surrounding insulation, occupies the full width of the rotor-slot in which it is placed, the rotorwinding being retained, in its slots, by means of slot-closing wedges 27. The stator and rotor slot pitch sections of the lamination are further divided into rectangular segments as shown in Figs. 2b and c. To determine the core loss in one slot pitch section, loss in each rectangular segment is calculated and then the losses for all segments under the slot pitch section are added.

Why does a close slot of stator winding have more reactance?.

Answer (1 of 2): First let's see what happens if we use closed slots: Closed slots → No air gap →Less Reluctance →More leakage flux → Less Magnetising current.

Analysis of Natural Frequency, Radial Force and Vibration of Induction.

The three-phase induction motor is the easiest motor of this type to understand so these notes start with that type. The single-phase induction motor is more subtle and less efficient. It is discussed later. The magnetic field in the air gap from the voltage applied to the stator: The stator has three sets of windings.. The rotor slot open ing width has been chan ged according to.... the efficiency of PMM is more than 5% higher than that of the induction motor of the same specification.... -fed fractional-slot.

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. (i) Open slots: In this type of slots the slot opening will be equal to that of the width of the slots as shown in Fig 10. In such type of slots assembly and repair of winding are easy..

Design of Stator - Induction Motors - BrainKart.

In general, open or semi-closed stator slots are employed in induction motors. In semi-closed slots the slot opening is much smaller than the width of the slot, and winding is more difficult and time consuming to manufacture compared to open slots. However, the air gap characteristics are better compared to the open type. Closed Slot Induction Motor - Top Online Slots Casinos for 2022 #1 guide to playing real money slots online. Discover the best slot machine games, types, jackpots, FREE games. Skewing angle for open rotor slot induction motor is equal to a slot pitch. May 23,2021 - the rotor slots are slightly skewed in squirrel - cage induction motor toa)increase the strength of rotor barsb)reduce the magnetic hum and locking. Slots are usually skewed, why squirrel cage rotor slots are usually skewed.

Optimal Slot Opening Width for Magnetic Noise Reduction in Induction Motors.

The use of slot wedges made of magnetic material in a synchronous and induction motor or generator makes possibility to increase the efficiency of the machine. This paper presents the experiences acquired in design, installation, testing and exploitation of the magnetic slot wedges on two relatively large hydrogenerators of rated output 34 MVA, 10.5 kV, 50 Hz, 187.5 min-1, cos ϕ = 0, 8.. This paper presents a comprehensive comparison between squirrel cage induction motors optimally designed with single and double cages for direct main-fed applications. The effect of adopting open and closed rotor slot geometry is also deeply investigated. The design-based comparison makes use of an innovative fast and accurate performance evaluation method embedded into an automatic design.
