Performance simulation of switched reluctance motor drive system operating with fixed angle control scheme

This invention is an easy-suck nursing bottle and a fixing disc mounted between the bottle mouth and a nipple secured on the above by a cover skirt for attachment of special suction means. A flexible internal suction pipe communicating with the nipple is provided at the bottom end thereof with a weight and a float permitting the bottom end of the pipe to float on the liquid surface by the float and also the opening at the bottom end of the pipe to be maintained constantly at slightly below the liqiud surface so that liquid can always be sucked from around the surface of the liquid in the bottle.
