    One of the main problems associated with the design and application of active magnetic bearings is excessive heat. Heat is generated by two primary mechanisms. The first heating source comes from eddy current loss. Eddy currents are electric currents driven within conductors by a dynamic magnetic field located in the conductor. Eddy current loss in a magnetic bearing are caused by the rate of change in the magnetic field. The relative motion creates a rotating flow of current inside the conductor

    without causing excessive wear. The bearing is intended to fulfill this need by providing a smooth surface and mechanism that allows a shaft or component to move independently without causing damage in the form of wear to its support. Bearings themselves can be classified in terms of the motions that they allow, the particular principle of operation that they implement and the direction of applied loads that they are capable of handling. The specific design of bearing that will be evaluated in this report

    Introduction A magnetic bearing is a type of bearing that holds up a load using magnetic levitation. Scientists first discovered the magnetic effects in magnetic minerals in 500B.C. In the late 20th century, scientists began developing ways where this magnetic effect could be implemented into a bearing, creating magnetic bearings. Today, magnetic bearings can be found in many applications where no physical contact is required or extreme environmental conditions exists, including very high and low

    Rolling-element bearings in electric motors support and locate the rotor, maintain a small and consistent air gap between the rotor and stator, and transfer loads from the shaft to the motor frame. The correct bearings for an application let a motor run efficiently across its design speed range, minimize friction and power loss, produce little noise, and have a long service life. On the other hand, bearings can be quickly ruined when a motor is used improperly. For example, the deep-groove ball bearings optimized

    Investigating the Factors that Affect the Acceleration of a Ball Bearing Down a Ramp I intend to investigate what factors affect the acceleration of a ball bearing down a ramp. I will measure how long the ball bearing takes to roll down a ramp, and my other variable will be to measure the final velocity of the ball bearing rolling down the ramp. Using this information I will then be

    something heavy. The pun indicates that if one cannot bear the truth (which is a very heavy object placed on the heart) than one cannot bear new life. In order to be reborn one must suffer the bearing of truth. When Oedipus says, "I, Oedipus, who bear the famous name." (Sophocles, 715), he indicates that he is bearing the name and therefore must bear the fate that is set for him in order to conceive new life. In order for Oedipus to fully bear his name he must accept the responsibilities that follow; He

    length of axial elements of the core. This apparatus must conform to certain requirements. It needs to be designed so that the specimens will be held with its axis in a vertical position by three symmetrically placed studs or posts of hardened steel bearing against the lower end. The end of the studs that bear against the surface of the specimen need to be rounded to a radius of not less than 6 mm and not more than 13 mm. The apparatus needs to allow for the measuring of specimens of different nominal
