With increasing usage of induction motor due to the its reliability and economical reason, not only it is common to be found at home but it is also widely use in marine environment for pumps, compressors etc. However, overheating of the winding can reduce the life span of the induction motor and cause potential danger. Hence, in this project, a 1MW induction motor will be modelled out using existing Finite Element Analysis (FEA) software. Both electromagnetic and thermal properties of the induction are needed to be analyzed. In order to so, two different software will be used; Ansys Maxwell and Motor-CAD. Anysys Maxwell is used for analyzing the electromagnetic properties of the induction motor when operating at steady-state. Core loss and flux density of the induction motor are extracted and observed. Water jacket will be added to the current induction motor design to simulate water flowing. The core loss of the induction motor is an important input for Motor-CAD when doing thermal modeling of the induction motor. The report will be focused on knowing how the temperature of the induction motor will behave when water is injected through the water jacket of the induction motor.
