Myeong Jin Koa, Sung-Ho Leea, Soon Sub Parka* ABSTRACT In this study, a 2.2 kW super-premium (IE4) class 4-pole three-phase induction motor was designed and developed. We compared this prototype motor with the industrial induction motors sold by leading international companies. We designed and fabricated a stator, an Al rotor, housing, bearing front and rear

Circuit World ISSN: 0305-6120 Article publication date: 6 April 2020 Issue publication date: 7 October 2020 Abstract Purpose The purpose of this paper is to study the development of novel multiphase induction motor (MPIM) with copper die cast rotor in the drive system of electric propulsion vehicles (EPV). It is estimated that the manufacturers are
Ren Liu1,2, Yuejin Zhao1, Xu Yang3 and Gen Wang4 Published under licence by IOP Publishing Ltd Abstract The energy conservation of electric motor system is the key of industrial energy conservation. With the implementation and acceleration of electric motor energy efficiency improvement plan, more and more electric motors are knocked out. High-efficient remanufacturing of electric motor refers to improving
Qian Zhang, Huijuan Liu, Member, IEEE, Zhenyang Zhang and Tengfei Song Abstract According to the demands of the small commercial electric vehicle (EV) traction driving system, an 18kW inverter-driven induction motor (IM) with a die-casting copper squirrel cage rotor for traction drive was designed and evaluated. The 2D finite element model of the designed IM

Soby T. Varghese; K. R. Rajagopal; Bhim Singh Abstract t is well known in the market that the copper rotor motor can give good efficiency at par with the new era motors, and can handle higher temperatures to qualify for electric vehicle application. Being a heavy metal, die-cast copper rotor manufacturing needs absolute care for faithful rotor
