Abstract
One of the main power stations in Zimbabwe has its generators located 100m underground. Elevators that used to carry people to the underground plant are not functional anymore due to old age and corrosion of the hoist way blade and guide rails. A system with an electromagnet actuator attached to the elevator car and its core shaped in the form of the letter 'E' used for coupling the magnetic flux between the coil and the hoist way rail blades was designed. Pairs of coils are wound on the actuator core in a manner that produces both side-to-side and front-to-back forces that are controlled by adjusting the current being supplied to the coils. The electromagnets fixed to the car supply the force of attraction between the actuator and guide rail, which then keep the car suspended; the motor is used to provide a driving force for the up and down movement of the car. The research satisfied the 9th Sustainable Development Goal of 2015, thereby contributing towards sustainability.
