Linear elevators using cylindrical linear induction motor (CLIM) increases the assemblies gradually in Japan. It, however, was published few scientific paper concerning the linear elevator analysis. This paper deals with CLIM as the actuator for vertical motion and linear induction motor-driven elevator, that is Linear elevator, our investigation revealed as follows; (1) The constitution of the linear elevator using CLIM is comparatively simple, the good motion characteristics was obtained by means of vector control. (2) The developed CLIM has the thrust/input of 43.2N/kVA, the simulated characteristics of starting thrust by the equivalent circuit constants agreed with the measured values. (3) Thrust of the CLIM has thrust ripples in twice frequency, 32Hz, of the driving frequency, natural frequency in the transmission mechanism was 15.4Hz.<br>The linear elevator developed by the authors was almost satisfied the target specifications of the conventional elevator.
