Abstract
In the previous paper, the author reported on the parasitic mutual inductance between primary windings in the two-phase linear induction motors, and on the distortion of air gap flux distribution affected by the mutual inductance. In this report, investigation has been carried out concerning with the influence of mutual inductance between primary windings on the stationary characteristics of two-phase linear induction motors.
Calculation is done for a few two-phase models using the circuit equations with the introduced mutual reactance Xm. The calculated results have confirmed that the effect of mutual reactance on stationary characteristics is less remarkable than expected and that the reduction in force and output is only five to six percents.
Measurements of the stationary characteristics are carried out with a stator drive model running on a secondary conductor plate ten-meters long. The calculated and measured values agree closely.
From the present work it has become clear also that the speed-force characteristics of a two-phase linear induction motor is drooping and linear in the whole slip region. Accordingly, their characteristics are very suitable for servo-motor or positioning control devices.
