Proposed is an air gap adjustment apparatus. The apparatus is for enabling an air gap between the inner surface of a stator and the outer surface of a rotor, which are installed in an inner space of a housing, to be uniform overall. A plurality of fastening holes are formed so as to surround a shaft through hole of an end plate constituting the housing. A fastener, which has passed through a bearing housing of a bearing, is fastened to each fastening hole so as to mount the bearing to the end plate. An adjusting member body of an adjusting member, which has passed through the bearing housing, is positioned in an adjusting member seating part which is formed at the entrance of each fastening hole. The adjusting member rotates about the adjusting member body so that a head part may adjust the position of the bearing.

A motor control center (MCC) for an industrial automation system, includes an enclosure housing comprising a plurality of sections, including a first section having one or more buckets, including a first bucket, a first bus bar, a second bus bar, and a third bus bar extending horizontally across the first section along a back plane of the enclosure housing, and a first electrical component, configured to perform one or more functions of the MCC, disposed within the first bucket of the first section. The first electrical component is directly electrically coupled to the first set of bus bars such that the first electrical component draws a first phase of power from the first bus bar, a second phase of power from the second bus bar, and a third phase of power from the third bus bar.

An alternator includes a housing and a rotary shaft. The alternator includes one or more brushes supported by the housing. The alternator includes a slip ring assembly coupled to the rotary shaft for rotating with the rotary shaft. The slip ring assembly includes one or more slip rings. The one or more slip rings include a body portion defining an outer surface. The one or more slip rings also include an oxide layer disposed on the outer surface of the body portion. The oxide layer is non-uniform. The oxide layer is formed on account of a thermal oxidation process of the one or more slip rings during an operation of the alternator. Further, the thermal oxidation process for formation of the oxide layer initiates when an operating temperature of one or more components of the alternator lies within a predetermined temperature threshold range.
