In the current paper, studies carried out to design an eight pole electromagnetic bearing have been presented. The magnetic levitation force, accounting the copper and iron losses, was maximized for the given geometric constraints. Derivation of winding constraint equation in terms of wire diameter, number of turns, and dimensions of pole has been presented. Experiments were conducted to establish the constraints related to temperature rise. Finally, the dimensions of the electromagnet for maximizing the force obtained using numerical optimization have presented.
