Abstract: A method for controlling magnetic bearings is disclosed. More specifically, this method moves the rotor position setpoint away from the center point between two opposing bearings and closer to one of the bearings. Assuming the force on the rotor is unidirectional, the bearings will be more stable and will be able to exert more force on the rotor. The bearings require less current, thereby allowing for the reduction of the winding size, and the power consumption of the bearing is decreased. The movement of the shaft in one direction or the other necessitates adaptive control, or the alteration of the dynamic control algorithm to maintain optimal performance by accounting for different system stability requirements.

Abstract: A shape retaining flexible connector apparatus for supporting flashlights, lamps, etc., is provided. The shape retaining flexible connector apparatus includes a formable support member, one or more joint forming members associated with the support member and a cover member.
