Effects of temperature and rotor length on force in tubular
linear induction motors with blocked rotor
R. Haghmaram, A. Shoulaie
This paper is concerned with the study of several parameters effects on longitudinal force applied on the rotor in the generator driven air-core tubular linear induction motors with blocked rotor. With developing the motor modeling by involving temerature equations in the previous computer code, we first study variations of the coils and rings temperatures and the effect of the rotor force. In the next section, the effect of the rotor length on the rotor force is studied and it is shown that there is an almost linear relation between the rotor length and the rotor force. Finally we have given the optimum time step for solving the state equations of the motor and calculating the force. By this time step the code will have reasonable speed and accuracy. These studies can be useful for the force motors and for finding a view for dynamic state analysis of the acceleration motors.
