Pneumatic Capsule Pipeline (PCP) systems are being increasingly used for freight transportation in selected industries like mining, tunneling and also in hospitals, drive-in banks, postal centers and airports. The widespread use of large PCP systems is achieved with the use of Tubular Linear Induction Motors (TLIM). TLIMs provide a non-intrusive system for the propulsion of the capsules inside the pipes. The need for an efficient and user-interactive design procedure for a TLIM pump to be used in PCP systems has fueled this research project. A user-interactive procedure was developed to design a highly detailed and efficient TLIM which generates the required electromagnetic thrust to propel capsules at the specified rated speed over long distances. Systems based on this design were recorded to be operating at about 75% efficiency which indicated a 7.5% increase in the efficiency as compared to previous designs. Future applications of such systems could involve high- speed, quiet and environmentally friendly freight and passenger transportation systems.

This dissertation studies the tubular linear induction motor (TLIM) for application in a pneumatic capsule pipeline (PCP) system. The TLIM concept is used to develop a non-intrusive capsule pump for the PCP to transport freight. Employing the non-intrusive capsule pump allows the capsule free passage through the pump, thereby increasing the system throughput. In this dissertation, the TLIM equations and TLIM design procedure for the PCP are developed. The fluid mechanics equations related to the PCP and used in the PCP design procedure are given. The performance of the TLIM is calculated based on the equivalent circuit models. The influence of the longitudinal end effects, which reduce the performance of the TLIM, is also observed with the end effects incorporated into the equivalent circuit model. In addition, the net normal force in the TLIM, which can be either repulsive or attractive, depending on the capsule speed, is also analyzed. Using the developed equations and procedures, designs of the TLIM for a one-meter diameter PCP system are presented. Then, a performance evaluation of the selected TLIM design is made. Finally, experimental data obtained from a small-scale laboratory PCP-TLIM are used to verify the theory, and a comparison of the theoretical predictions with the measured results is presented.

Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor, a new SRM driven linear actuator is proposed as a replacement for the traditional hydraulic system. The key factor is to improve drive system reliability without losing the high thrust/ high power density characteristic of the original system. Through the Landing Craft Air Cushion (LCAC) project example, the detail of the magnetic design is done step-by-step to maximize the SRM power density. The technique credibility is crosschecked by both the SRDaS software and the finite element method. For further improvement of system reliability, converter structure, sensorless control and fault tolerance ability are also investigated. Both the computer simulation and the experimental results verified the validity of the high thrust linear actuator design. The Linear Induction Motor (LIM) is another type of low cost, low maintenance linear actuator for medium/high speed application. There are several constraints which should be considered during the LIM design procedure. The motor manufacturer needs to minimize the motor weight to save material and also limit the total supply current for thermal consideration. The drive designers are always looking for the maximum thrust with less supplied voltage. The wide operating speed requirement also makes the design decision more complex. In the research new asymmetric structure is proposed in the design, which can ideally double the design option from just even coil numbers per slot to the full integer range. The asymmetric structure has the potential to introduce a new balance point between the low-speed and high-speed performance of the LIM. Experimental results demonstrate the significant gain of the asymmetric motor compared with its symmetric counterpart. The airgap length is also found to be a key factor for the application in the experiments.
