On The Characteristics Of Small Size Three Phase Induction Motor With A Solid Iron Potor

강괴회전자를 가진 소용량 3상유도전동기의 특성 해석에 관한 연구

The solid-iron rotor induction motor is the squirral cage type induction motor with its rotor core consisting of solid iron in stead of a laminated core. The specific feature of this motor are that its structure is simple and firm, and therefore provides the great convenience in its operation and that its starting characteristic are excellent. this study is aimedto derive the equation for theroretical evaluation of the speed-torque characteristics of the motor by use of maxwell's equation. Through the series of test on the speed-torque characteristics of this motor which is experimentally constructed, we have proved the feasibility of the equaiton which is derived theoretically to calculate the torque of the motor. In addition we have obtained its general charastristics experimentally.
