This paper provides a direct-drive electromagnetic active suspension system which consists of a double- stator air-core tubular permanent magnet linear motor (DATPLM) in parallel with a coil spring. The topology of magnetic pole can be radial-magnetized, axial- magnetized and Halbach-magnetized. The proposed DATPLM can operate in both motor mode and generator mode which allows for bidirectional energy...
This paper investigates the thrust characteristics of the tubular transverse flux permanent magnet linear machine (TFPMLM), including theoretical analysis and numerical calculation. The influence of structure parameters on the thrust force and cogging force characteristics is analyzed in detail. Special attention is paid to the length of stator segment, height of permanent magnet (PM), air-gap length...
Thrust magnetic bearings, which can regulate axial displacement of a rotor shaft, have been used for high speed rotation. However, conventional thrust magnetic bearings have many problems in manufacturing and assembling caused by a large disk rotor of itself. Therefore, in the previous paper, we proposed a 1-axis active control type thrust magnetic bearing with a cylindrical rotor instead of the large...
This paper deals with the development of a tubular permanent magnet linear drive with radial magnetized armature and discrete wound coils mounted on a star-shaped stator part. The rated force of the developed machine is 500 N per segment. This presented particular design results in a very economic product because all primary parts, except of the permanent magnets and coils, are made of standard non-laminated...
