Induction Motors Subject To Regular Voltage Fluctuations: Stator And Rotor Current Analysis From A Heating Perspective, Kun Zhao, Philip Ciufo, Sarath Perera
Induction Motors Subject To Regular Voltage Fluctuations: Stator And Rotor Current Analysis From A Heating Perspective, Kun Zhao, Philip Ciufo, Sarath Perera
Faculty of Engineering and Information Sciences - Papers: Part A
Induction motors are widely applied in industry. Their performance strongly depends on relative power supply quality, such as voltage sags, harmonics, voltage unbalance and voltage fluctuations. This paper investigates the impact of voltage fluctuations on induction motor performance, particularly the stator and rotor current variation characteristics. An induction motor steady state analysis method is proposed when the motor is subjected to regular voltage fluctuations. The dynamic model of an induction motor is used in order to represent the induction motor instantaneous response. Furthermore, the correlative simulation and experiment work are presented in order to illustrate the impact of voltage fluctuations. …
It Consultants' Voluntary Contract Termination - A Psychological Contract Perspective, Gro Bjerknes, Karlheinz Kautz
It Consultants' Voluntary Contract Termination - A Psychological Contract Perspective, Gro Bjerknes, Karlheinz Kautz
Faculty of Engineering and Information Sciences - Papers: Part A
This research explores the question why IT consultants terminate their employment contracts in a labour market with job drought, downsizing and salary cuts when they were among those who kept their jobs during layoffs. A process model for the maintenance of a psychological contract between employees and employers is presented, which combines the concept of psychological contract with a theory of the relation between intrinsic motivation and management practices and with theories of identity, self-esteem, influence and power. The research verifies and specifies the model based on a revelatory case study. The model helps explaining IT consultants' behavior of voluntarily …
