This paper presents a development of a linear driving apparatus system for the vertical movement system such as ultra super high buildings or deep under ground upto approximatly 50m of depth. The contents deal with as follows.
(1) As a double-sided permanent magnet type linear synchronous motor (LSM) is useful to minimize a magnetic attractive force and can produce a strong thrust with small size, the vehicle weighted 270 kg can be vertically to move up and down 2m smoothly.
(2) Analysis and calculation of the thrust, the influence of each parameter to the thrust, an armature reaction and the magnetic attractive force are examined.
(3) Characteristics of LSM (equivalent circuit, vector diagram) are analysed similar to the rotating synchronous machine and the test results are compared with the calculated values with good agreement.
