For depending rotor slot shapes, top and bottom width values of the slots, teeth widths, slot opening widths, separator heights etc. will be changed. Furthermore, rotor and

Following design data have been obtained during the preliminary design of a 3 phase, 850 kW, 6.6 kV, 50 Hz, 12 pole slip ring induction motor. Gross length of stator core = 45 cm, internal diameter of the stator core = 122 cm, number of stator slots = 144, Number of conductors per slot = 10. The stator–rotor slot combination is an important parameter in the design of high-voltage induction motor (HVIM). The different design of the stator–rotor slot combination will have an effect on the performance of the HVIM, such as torque, air-gap flux density, loss and so on. In order to analyze its influence, 10 kV, 1000 kW HVIM is taken useful in design of such machines. It is shown that a useful understanding of how different slot shapes work may be developed through the use of frequency response curves that describe rotor slot impedance as a function of rotor frequency. Good starting, running and stray loss characteristics can be identified in such frequency response curves. Know about the working principles and design of A.C. Induction motors, with emphasis on the the exact analysis of rotor rotation. Also know about the Cogging & Plugging phenomena, which are very important for any induction motor. Know about the various losses and comparison of induction motor with a mechanical friction clutch for understanding slip. Slip and Rotor Impedance. The inductive reactance will change with the slip since the rotor impedance is the phase sum of the constant resistance and the variable inductive reactance. When the motor starts rotating the inductive reactance is high and impedance is mostly inductive. The rotor has a low lagging power factor. When the speed Download scientific diagram | Stator and rotor slot types and slits from publication : Investigation of Stator Furthermore, studies on magnetic and electrical design. 18 Sep 2018 Why are there two different designs of rotor construction for induction motors? We will explore this in the video. Be a Learn Engineering

An induction motor embodiment includes a stator defining a stator bore, the stator including a stator yoke having a stator yoke thickness and a plurality of stator teeth, the teeth having a common length, with each of the stator teeth including a stator tooth center portion that extends from a stator tooth bottom portion proximal the yoke to a stator tooth tip portion, with adjacent stator

10. The induction motor of claim 1, wherein an air gap distance between said stator bore and said rotor is between 0.5 millimeters and 0.8 millimeters. 11. The induction motor of claim 10, wherein said rotor tooth bridge corresponding to each rotor slot is between 10% and 70% larger than said air gap distance. 12. Rotor design. The rotor comprises a cylinder made up of round laminations pressed onto the motor shaft and a number of short-circuited windings. The rotor windings are made up of rotor bars passed through the rotor, from one end to the other, around the surface of the rotor. The bars protrude beyond the rotor and are connected together by a Sep 30, 2019 · Control of Induction Motor Characteristics by Cage Rotor Design. The equivalent circuit of the induction motor the term X 2 is leakage reactance. It is the reactance due to the flux of the rotor that does not interact with the stator of the motor.

Disc brake systems can account for heat dissipation in two ways: either the rotors will have a ventilated design, or the brake pads will contain a slot on the surface. These vents and slots provide passages so air circulation can effectively cool the rotor. Proper heat dissipation is extremely important for prolonging the life of your rotors. An induction motor embodiment includes a stator defining a stator bore, the stator including a stator yoke having a stator yoke thickness and a plurality of stator teeth, the teeth having a common length, with each of the stator teeth including a stator tooth center portion that extends from a stator tooth bottom portion proximal the yoke to a stator tooth tip portion, with adjacent stator See full list on copper.org Dr.basem 2/29 Construction : A 3-phase induction motor has two main parts (i) stator and (ii) rotor. The rotor is separated from the stator by a small air-gap which ranges from 0.4 mm to 4 mm, depending on the power of the motor [See Figure (4.2)]. In this type, the rotor consists of bars of copper or aluminum accommodated in rotor slots. In case slip ring induction motors the rotor complex in construction and costlier with the advantage that they have the better starting torque. This type of rotor consists of star connected distributed three phase windings.
