Emergency motor switch-on happens occasionally while operating a doublesquirrel-cage motor at full supply voltage with the rotor blocked (e.g., in coal mills). After releasing the blockage, the by now heated motor is started up again. However, the mechanical stress caused by the increased temperature poses considerable hazards to the squirrel-cage winding. This paper presents a double-cage induction motor model for analysis of thermal fields in transient operation. The thermal field for the rotor of a doublesquirrel-cage motor of soldered or cast structure, operating in the conditions described, has been calculated in the present paper using a thermal network method. Measurement results have been presented for the double-squirrel-cage winding temperature for a soldered cage construction in the blocked rotor state.

“…The thermal computation is tightly coupled to the electro-magnetic and fluid-dynamical results. The resistivity of stator windings and squirrel cage is updated in accordance to the thermal field calculation result until the maximum difference of temperature between two adjacent steps is less than 0.01℃ [11]. …”

AbstrakDesain yang optimal dari motor induksi besar adalah proses yang melibatkan keterampilan listrik dan mekanik serta keterampilan tentang dinamika termal dan fluida. Di Kata kunci: medan arus Eddy, metode elemen hingga (FEM), medan fluida, motor induksi asinkron berpendingin udara, simulasi Multiphysics Abstract Optimal design of large induction motor is a process that involves electrical and mechanical skills as well as thermal and fluid dynamic skills. For recent machine layouts, one cannot rely on standard analysis methods. In multiphysics simulations which are done by weak coupling finite-element method, rotation boundary values on interface between air gap and rotor cannot be applied directly for fluiddynamical analysis. A novel multi-component fluid method is proposed to deal with the influence of rotor rotation upon the air convection. This paper investigates a 3-D multi-physics simulation used in simulation

“…In the past, detailed thermal analysis of induction motors has been carried out for rotary machines [5], while this paper focuses on the transient temperature variation on the active area of the conductive plate of the linear counterpart. The thermal analysis of a LPMSM deals with the eddy current losses into the magnets of the synchronous machine and the consequent limits on armature excitation to avoid demagnetization during operation.…”

Content is final as presented, with the exception of pagination. Abstract-The engine size of modern passenger transport aircraft is principally determined by take-off conditions, since initial acceleration requires maximum engine power. An electromagnetic launch (EML) system could provide some or all of the energy required at takeoff so that the aircraft engine power requirement and fuel consumption may be significantly reduced. So far, EML for aircraft has been adopted only for military applications to replace steam catapults on the deck of aircraft carriers. This paper will describe the potential application of EML to propel civil aircraft on the runways of modern airports. A comparison of synchronous and asynchronous electrical motor systems designed to launch an A320-200 sized aircraft is presented. The paper also describes a solution of the transient heat transfer problem applied to the conductive components of EML systems.
