Design of Induction Motor, shape and number of stator and rotor slots.

Oct 01, 2016 · The medium and high power induction machines are usually built with prefabricated insulated coils. In these cases, by technological reason, the stator is designed with rectangular shape open slots. Because of the large width of the open slot, the air-gap magnetic field is distorted (comparatively with the situation of other types of slots shape), having high order space harmonics with.

Owing to the stator open slot structure of the high-voltage motor, the magnetic field distribution in the motor will be uneven, and the performance of the motor will deteriorate. When the slots are embedded with magnetic material slot wedges, the magnetic field of the motor will be changed. In this article, taking a 10 kV/1000 kW high-voltage induction motor (HVIM) as the prototype, the two.

INDUCTION MOTOR - National Institute of Technology.

Mar 01, 2019 · The slot width and height of slot are varied keeping all other dimensions of IM constant. The slot width is increased till the slot tooth width is mechanically feasible and the stator slot tooth flux density is within the permissible limit. Table 3 shows the dimension of the stator slot. The effects of variation in stator slot dimensions are. 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. This article deals with the usage of four-layer windings in induction machines. The technology of manufacture of these windings is more complicated, but better properties of the motor may be reached. In the article, a four-layer winding is compared with traditional double-layer winding and the differences in the design of the machine are described. Obtained theoretical insights are used to.

Open and Closed Rotor Slots Design of Single and Double Cages.

The impact of the rotor slot number selection on the induction motors is investigated. Firstly, analytical equations will reveal the spatial harmonic index of the air gap magnetic flux density, connected to the geometrical features and the saturation of the induction motor. Then, six motors with different rotor slot numbers are simulated and studied with FEM. The stator is identical in all. 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. Oct 12, 2017 · 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.

Optimal design of stator and rotor slot of induction motor.

Why do open slots are allowed in stator and rotor of synchronous machine while they are avoided in stator of Induction Machine? Because flux from stator to rotor (IM) and from rotor to stator (in SM Cylindrical rotor), will have nearly same linkage. I know large air gap between stator and rotor of synchronous machine make it less noisy. Find info on Warehousing and Storage companies in Khabarovski Kr., including financial statements, sales and marketing contacts, top competitors, and firmographic insights. Describe design of induction motor. Explain winding insulation, slot space factor, shape of slot, open slot semi closed slot and closed slot all are explaine.

Types of Magnetic Leakage Flux in Induction Motor.

Find info on Other Support Activities for Transportation companies in Khabarovsk, including financial statements, sales and marketing contacts, top competitors, and firmographic insights. Open type slots: The winding which is formed before placed into slots is called former winding. Leakage reactance is less, therefore, more amount of power will be transferred from stator to rotor. The average air gap length between stator and rotor is high, therefore, machine draws more exciting current. Airgap length is irregular, and it.

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 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 21. The impact of the rotor slot number selection on the induction motors is. Question is ⇒ the induction motors which are provided with open slots have, options are ⇒ (a) more break down torque, (b) less break down torque,. The paper presents some aspects of magnetic wedges application in electrical machines. In such type of slots assembly. 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.

Induction motor - Electrical Machine Design: Why do open.

Induction motors depends upon the shape of the slots (i) Open slots: In this type of slots the slot opening will be equal to that of the width of the slots. In such type of slots, assembly and repair of winding are easy. However such slots will lead to higher air gap contraction factor and hence poor power factor. (ii) Semi closed slots: In.

Why are closed slots generally not being used in an induction.

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. Answer (1 of 5): 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. Sep 27, 2016 · Induction Motor is an AC electric motor, having a stator and a rotor just like other motors, but the working principle is a little different which would be discussed further. There are two types of Induction Motors, one is named as Single Phase Induction Motor , while the second one is named as 3 Phase Induction Motor.

Jul 06, 2022 · The three phase induction motor is a rotating electronic machine that is operated for a three-phase supply. This 3-phase induction motor is also called an asynchronous motor. These AC motors are of two types such as squirrel cage and slip-ring type 3-phase induction motor. A 3-phase induction motor (A.C.) consists of two major parts such as.

Open Slots In Induction Motor - Armature Winding of Alternator In.

Apr 08, 2021 · In induction motors with closed rotor slots the enclosure upper part of the rotor slot saturates during the machine operations, involving an additional non-linearity in the machines behavior. 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.
