Three Phase Induction Motor Construction | ATO.com Induction motor, also known as asynchronous motor, is a kind of AC electric motor. According to the different power phase, it can be divided into single-phase and three-phase. The main construction of induction motor is composed of two parts - stator and rotor. In addition, there are end bells, bearings, motor frame and other components. CHAPTER 3 INFLUENCE OF STATOR SLOT-SHAPE ON THE ENERGY ...
A rotor slot shape of induction motor for electric vehicle is optimized by FEM with the numerical techniques. To optimize the rotor slot shape, two objective function and 3 variables are defined, and the optimization algorithm is developed. To verify Shape Design of a Rotor Bar for Improving Starting Torque Shape Design of a Rotor Bar for Improving Starting Torque And Running Efficiency in Squirrel Cage Induction Motor Ha Jeong Lee1, Sang Hyeon Im1 and Gwan Soo Park1 1School of Electrical and Computer Engineering, Pusan National University, Busan 46241, South Korea gspark@pusan.ac.kr This paper presents a design of rotor bar to improve the starting torque. Squirrel-cage rotor - Wikipedia A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor.It consists of a cylinder of steel laminations, with aluminum or copper conductors embedded in its surface. In operation, the non-rotating stator winding is connected to an alternating current power source; the alternating current in the stator produces a rotating magnetic field.
