Development of permanent magnet tubular linear motor and position feedback device based on Hall sensor

This thesis deals with the permanent magnet tubular linear motor (PMTLM) including the design and the manufacture. The motor is designed to have large output force with the limited height which could be used as the vehicle vibration reduction device in the future applications. There are many limitations of this tubular linear motor, for example, the length of motor, the cost of whole design and the considerable output force. The electrical design and mechanical design are proposed in this paper. The Finite Element Analyse software Flux 2D is used in the project to model the permanent magnet tubular linear motor with a 2D axisymmetric boundary condition. In order to satisfy the limitations of the motor, all the simulations could be conducted by Flux 2D. Moreover, the Hall sensor devices are applied to detect the position; as a result, the total cost of the system can be reduced a lot. At last, a tubular linear motor is built and the experiments about the motor and the feedback device are conducted.
