When the motor runs at high speed (50~100HZ), it has a high overload capacity to ensure the constant power output of the motor. Product features. YVF2 series 3 phase squirrel cage induction motor is a new generation of variable frequency speed regulation motor developed to meet the needs of the market. It has the advantages of low noise, small

2002/11/6 · This paper presents the use of the finite element technique for determining the parameters of a three-phase squirrel-cage induction motor. The common parameters, in addition to the core losses and ratio of number of tums, are obtained from the finite element field solutions. The magnetizing characteristic and core losses curve are used to determine the flux

Squirrel Cage Rotor Three Phase Induction Motor. The rotor core is cylindrical and slotted on its periphery. The rotor consists of uninsulated copper or aluminium bars called rotor conductors. The bars are placed in the slots. These bars are permanently shorted at each end with the help of conducting copper ring called end ring.
