Numerical analysis of three dimensional steady state heat conduction in the rotor of an induction motor by finite element method

Heat transfer characteristics of external ventilated path in compact high-voltage motor

“…However, the increase of power density is bound to cause more serious overheating problem, which will reduce the motor efficiency. As a solution, controlling the range of temperature rise is a key factor affecting the efficiency of the overall design [1] . Therefore, it is necessary to analyze the fluid field and temperature field accurately and improve the cooling system capacity to ensure reliable operation of motor.…”

Impact of the Fan Design and Rotational Direction on the Thermal Characteristics of Induction Motors

“…Thus, this type of machine is suitable for industrial applications. Since the TEFC induction machine is sealed, the attached fan at the rear shaft of the machine plays the significant role of drawing the air surrounding the motor casing and carry the heat away from the machine [10]- [11]. The fan design and type can affect the air flow characteristics for this particular machine which eventually has an impact on the machine's thermal profile.…”

Approximate Analysis of Transient Heat Conduction in the Stator of an Induction Motor during Auto-transformer Starting

“…These techniques are useful when approximations to thermal circuit parameters and geometry are accepted. Numerical techniques based on either finite difference method [4,5] or finite element method [6][7][8][9][10][11][12][13] are more suitable for analysis of complex system. Rajagopal et al [14,15] carried out two-dimensional steady state and transient thermal analysis of TEFC machines using FEM.…”
