Energy Saving Inverter Controlled Magnetic Jack
The main purpose of this research is to propose and develop energy saving inverter controlled magnetic jack. It is an electromechanical load lifting machine which provides controlled linear motion to the load. The project is carried out as a result of increase demand for limited fossil energy. Energy saving of the system is achieved through the use of power electronic inverter connected to the induction motor with sensors installed in some part of the system. The regenerative energy of the system achieved through repulsion of the magnets and increase in thickness of the system coil housing is either saved in the system capacitor which could be re-used later or fed back to the mains. Results show that the system is efficient in energy saving and regeneration. A total of 35.99% energy is expected to be realized by the system at the end of the work. The work is also expected to open new door for researchers in this field.
