MAXIMUM ENERGY EFFICIENCY AND DRIVING FORCE OF LINEAR INDUCTION MOTOR IN ACCELERATING PERIOD

A linear induction motor used for high-speed trains requires a long accelerating time and a large quantity of accelerating energy. In addition, its starting torque must be sufficiently large. Linear motors used for purposes other than high-speed railway are usually started and stopped very quickly and frequently. Therefore, the operating characteristics (thrust, energy efficiency, etc.) of the linear induction motor in accelerating condition are very important from practical viewpoints. This paper analyzes the effect of secondary resistance on the input and output energy, accelerating energy efficiency, accelerating thrust, accelerating time, etc. The authors also derive the theoretical formula for the secondary resistance which maximizes accelerating energy efficiency, accelerating thrust or minimizes the accelerating time. As a result of this analysis, it is shown that if the exciting reactance is small, both the accelerating thrust and the accelerating energy efficiency can be maximized almost simultaneously by assigning an appropriate value to the secondary resistance. The validity of the theoretical analysis is confirmed in part by experimental study.
