FORCED OSCILLATIONS OF INDUCTION MOTOR

IFAC Proceedings Volumes, 1983
Abstract The general mathematical model of asynchronous machines is represented by means of a non linear either 5-th or 6-th order system of differential equations, according to the shaft elasticity is either taken into account or not. These models are sometimes linearized to study particular phaenomena, as for example forced oscillations due to ...

Single-Stage PV Array Fed Speed Sensorless Vector Control of Induction Motor Drive for Water Pumping

IEEE transactions on industry applications, 2018
This paper deals with a single-stage solar powered speed sensorless vector controlled induction motor drive for water pumping system, which is superior to conventional motor drive. The speed is estimated through the estimated stator flux.

V/F Control of Three Phase Induction Motor

2019 International Conference on Vision Towards Emerging Trends in Communication and Networking (ViTECoN), 2019
Control of induction motor (IM) is more important because most of the industry used the induction motor, and control in the cost of decrease the efficiency and performance of the machine.

Control of induction motors

IET 13th Professional Development Course on Electric Traction Systems, 2006
Induction motors have existed for many years but were always limited in their application because the supply needed for variable speed control could only be provided by rotary converters, otherwise a three-phase fixed supply could be used to give a fixed-speed control. [Reference 1].

Convolutional Discriminative Feature Learning for Induction Motor Fault Diagnosis

IEEE Transactions on Industrial Informatics, 2017
A convolutional discriminative feature learning method is presented for induction motor fault diagnosis. The approach firstly utilizes back-propagation (BP)-based neural network to learn local filters capturing discriminative information.

An Analysis of the Induction Motor [PDF]

Transactions of the American Institute of Electrical Engineers, 1935
For problems involving induction motors other than the usual balanced winding type operating under steady-state conditions, a general method of analysis is necessary. In this paper, a general analysis is presented, and in particular, its use in short-circuit problems is described.

Quantitative Comparison of Linear Flux-Switching Permanent Magnet Motor With Linear Induction Motor for Electromagnetic Launch System

IEEE transactions on industrial electronics (1982. Print), 2018
To incorporate the merits of simple and robust movers of induction linear motors and higher power factor and high efficiency of permanent magnet linear motors, a new long primary double-sided linear flux-switching permanent magnet (DSLFSPM) motor is ...

Direct-drive induction motors: using an induction motor as an alternative to a motor with reducer

IEEE Industry Applications Magazine, 2005
This article presents the performance and size comparisons of direct-drive induction motors with gearbox-driven systems. Three different low-speed applications with output speeds to the driven equipment ranging from 300-600 r/min is reviewed. In addition, permanent-magnet (PM) motor advantages and disadvantages are also discussed.

Theories of the Linear, Induction Motor and Compensated Linear Induction Motor

IEEE Transactions on Power Apparatus and Systems, 1972
The paper explains two new theories of the linear induction motor, and indicates that the end effect exercises very adverse influence on motor performances, and proposes the compensated linear induction motor as a measure to eliminate. the end effect.

Thermal Modelling of an Induction Motor

IEEE Transactions on Power Apparatus and Systems, 1983
The comparison of motor losses is a significant item in the study of inverter control strategies for variable frequency, variable speed ac drives. For our study, since it is necessary to differentiate small changes in loss, we have decided to use steady state temperature rise as a direct indicator of loss rather than measurement as the small difference
