This paper presents a solution that an analytical model for an induction motor and the formula of regenerative power and instantaneous torque are derived. based on the spiral vector. The torque is controlled linearly through variations of the slip angular velocity, based on the field acceleration method (FAM). And also PWM inverter fed induction motor drives is schemed to be easily a regenerative drive. The voltage source inverter fed induction motor drives that regenerative power occurs with back current type is presented, to easily controlled the feedback power and to proper the adaption of energy shaving drives. The experimental tests verify the performance of the FAM, proving that food behavior of the drive is achieved in the transient and steady state operating condition, and are discussed to save the power that regenerative power is measured at the operating acceleration or deceleration of servo system.

본 연구는 스파이랄 벡터에 기초한 유도전동기 모델의 해석을 나타내고 이 해에 기초한 자계가속법(Field Acceleration Method)에 의해 순시 토크 제어와 회생전력 해석을 나타내었다. 전압지령형의 PWM제어에서 전압형 인버터에 의해 전동기가 동작할 때 전력회생이 수식으로 해석 되었다. 전압지령형의 전압 PWM 인버터에 의한 유도 전동기의 속도 서보시스템을 설계하고 이 속도제어 시스템을 이용해 가감속시의 소비(회생)전력을 측정하여 실제 시스템에서 전력 절약정도를 검토하였다. FAM법에 의한 실험을 행하고 유효성을 확인하였다. 고정자 저항의 측정오차나 변동은 여자전압에 맥동이 생겨 출력 토크에 영향이 나타는 것을 알 수 있었다.

This paper based on spiral vector, three phase induction motor is described a detailed modeling by a phase segment methode. Based on this model, A torque control and the equation of regenerative power for the induction motor drive, based on the field acceleration method(FAM), is presented. The speed control system is designed to be applied voltage source inverters that is easy the current type feedback of power regeneration for motor drive. The ability of shaving power to be measured power regeneration has been investigated in speed acceleration and reduction. And it is change of stator resistance that the voltage commands include error, the ripple of exited voltage and torque occur from the results. The experimental tests verify the performance of the proposed regenerative drive for FAM, proving that good behavior of the drive is achieved in the transient and steady-state operating conditions.
