Induction Motors Thermal Analysis
Original scientific paper The temperature distribution over the cross-section of an induction motor is calculated at the steady state and transient condition. In order to develop smaller and more efficient electric motors, there is a necessity to carry out more thermal analysis in parallel with the traditional electromagnetic design. It has been found that attention to the thermal design can be...
متن کاملMagnetic Noise in Induction Motors
Noise in large high voltage induction motors (500Hp 18000Hp) may be airborne or magnetic in nature. Usually, large high voltage induction motors are custom built and tailored to meet customer’s demand. Since every motor is unique in its design, it is imperative to predict accurately the magnetic noise generation during design phase, this way avoiding expensive rework cost and not loosing the cu...
متن کاملINDUCTION MOTORS - PROTECTION and STARTING
It is well understood that induction motors draw higher currents during their starting operations than is the case under full load running conditions. Since the early days of induction motor availability, starting methods other than Direct-on-Line have been used, and in some cases mandated by Utilities, to reduce the effect of these high starting currents on the electrical distribution network....
متن کاملTwo Remarks on Induction Motors
This paper addresses two points: first, induction motors are shown to be flat, which implies they can be easily controlled by full-state feedback (for instance with a linearizing (dynamic) feedback); second, an exponential observer, relying on easily measurable variables (stator current and rotor velocity) is proposed.
متن کاملLabVIEW Simulation of Induction Motors
Abstract Knowledge of steady-state processes of induction motors is critical in the understanding of their operating principle. In addition to the vast, systematic theories in literature, computer simulations provide a keen insight to the mechanism. Suitable modeling methods enable motors to be simulated with various parameters. Many phenomena can be predicted without hardware experimentation. ...
