	Sealed motor rotor with ball bearing - US Patent 6577035 (Site not responding. Last check: 2007-11-06)
		In a sealed rotor motor, it is necessary to separate the environment on the rotor side from the environment on the stator side and prevent for example any flow of gas via the ball bearing or via the air gap between the rotor and stator.
		In the case of a sealed motor including a bell that encloses the rotor, the open end of the bell is bent radially outwards to form a rim (whose plane is therefore parallel to the plane of the annular seal) which is inserted between the stator assembly and the annular seal.
		The housing 30 of the ball bearing is in the form of a cylindrical recess with two different diameters, the first diameter at the open end of the housing being slightly larger than the second diameter at the bottom of the recess.

	Spindle motor structure using ceramic ball bearing for hard disk drive - US Patent 6342743 (Site not responding. Last check: 2007-11-06)
		The bearing mechanism according to claim 1, wherein a distance between the inner races of the first and second bearings is smaller than a distance between the outer races of the first and second bearings so as to apply pre-loaded pressure.
		Therefore, if steel balls are used in a bearing of a spindle motor in a hard disk drive having a load/unload mechanism, fluctuations with small amplitude occur between the inner and outer races and steel balls of the bearing when the disk drive is transported, etc. Consequently, fretting occurs in the contacting parts.
		A spindle motor of still another form of the present invention has rotor magnets that are held by holding means, which is formed on the shaft in one piece, and are disposed along a circumference whose center is a central axis of the shaft.

	Ball-Bearing motor (Site not responding. Last check: 2007-11-06)
		This localised heating causes the ball to expand in the hot area, causing a slight elongation of the ball, pushing against the inner and outer rings of the race.
		If the ball were stationary, this would cause the bearing to stiffen and sieze up, but when it's rotating (from the initial spin), this elongation causes the ball to push itself further round in the direction of rotation, sustaining the movement.
		During rotation the ball's "bulge" moves from the one race to the other, the local overheating is absorbed by the ball and the radius of the "bulge" becomes equal to the radius of the whole ball.

		The ball bearings are cheeper to replace than a sleeve bearing is to repair.
		The 6313 bearings are also more availible than sleeve bearings if the sleeve bearing cannot be repaired.
		Ball bearings have a set life that can be reduced by a number of factors, and as long as the oil wedge in the sleeve bearing is maintained the bearing should have a significant longer life.

		From prison, he was soon transferred to a mental institution where they tried to eliminate his "unorthodox political thinking" by horse doses of neuroleptics.
		Low voltage/high current electricity is supplied to the outer shells of both bearings, which makes the device rotate with incredible torque, though it's workings are not understood by electric theory.
		Marinov was convinced that the ball-bearing motor, whose operation defies present scientific wisdom, is a thermal motor running on the heat induced expansion of the balls inside the bearings.
