PROBLEM TO BE SOLVED: To solve problems that a structure of a sheet aluminum outside a cylindrical frame prevents the heat of a stator from conducting directly and that heat cannot sufficiently be dissipated because of a gap that is caused by dimensional dispersion in the conventional art....
An induction motor is an alternating-current motor in which a primary winding on one member (usually the stator) is connected to the power source and a polyphase secondary winding or a squirrel-cage secondary winding on the other member (usually the rotor) carries induced current. ...
(2003)have presented a complete survey on the various approaches to the parameter estimation ofinduction motor. A simple method for determining the squirrelcage induction motorparameters and problems in the determination of parameters with the two methods proposed in IEEE standard 112 was discussed (...
Motor Control Power Electronics Background To overcome the challenges associated with harmonic distortion in induction motors (IMs), various control strategies have been proposed to enhance their performance. Harmonic distortion in the AC side of IM drives can lead to inefficiencies, reduced lifespan, ...
motor current signatures and motor voltage signatures from other components. The standard deviation of one of the decomposed vectors is used as a statistical SITF criterion. The proposed criterion is robust to non-fault conditions including voltage quality problems and large mechanical load changes as ...
Problems to be Solved by the Invention In a conventional induction motor, an inner diameter part of a rotor iron core has two notches, so that when fitting the rotor iron core to a rotating shaft by shrink-fit, large distortion occurs in the rotor iron core, which causes a problem that ...
Equivalence Theorems, Analysis, and Synthesis of Single-Phase Induction Motors With Multiple Nonquadrature Windings, October 1956 AIEE, pages 913-16; it is not believed that anyone has provided a successful resistance split-phase motor which has solved the heating problems of the starting winding by...
The problem of two-dimensional heat flow in the stator of induction motor is solved by use of a finite element formulation and arch-shaped elements in the ... D Sarkar,AK Naskar - 《International Journal of Power & Energy Conversion》 被引量: 3发表: 2014年 Novel approach to analytical mod...
An object is to provide a vector control apparatus for an induction motor which is capable of correcting a set value of a mutual inductance so as to match an actual value thereof by
An induction motor comprises a stator and rotor totally enclosed in a case with no air communication through the case, an internal shaft mounted fan at each end of the rotor and an external fan and fan shield at one end to direct cooling air along the outer surface of the case. The moto...
