System for maintaining a vertical motor thrust bearing

Certain exemplary embodiments comprise a device and/or an electric motor comprising an elongated, substantially rigid rotor shaft, the rotor shaft defining a plurality of longitudinal flutes; and/or a method comprising: for an electrical motor, forming an elongated, substantially rigid, rotor shaft defining a plurality of longitudinal flutes; and assembling the rotor shaft with a stator of the electrical motor.

Industrial motor assembly comprising a vented rotor shaft

A vibration reduction assembly for isolating the top cover from the machine, for use in combination with a dynamoelectric machine having a cover for guiding air into and out of the machine while protecting the machine from airborne water and dirt. The vibration reduction assembly comprises a plurality of spaced neoprene pads provided between the cover and the machine, the pads of a density and size selected to obtain low transmissibility and amplification of vibration caused by the machine thereby reducing vibration of the machine; a plurality of closed cell foam rubber strips positioned between adjacent ones of the plurality of neoprene pads, the strips for filling space between the cover and for protecting the machine from incident atmospheric precipitation and dust. The cover is affixed to the machine with a plurality of bolts, each bolt engaging a neoprene washer and a neoprene sleeve to eliminate metal to metal contact.
