Cover for electric motor

DETAILED DESCRIPTION Among the several objects and features of the present invention may be noted the provision of a dynamoelectric machine which is connectable to an adjacent part while being simultaneously protected from moisture or contaminants; the provision of such a machine which reduces the time required for connection to the adjacent part; the provision of such a machine which has an effective seal; the provision of such a machine which provides unhindered access to fasteners; the provision of such a machine which reduces risk of damage to electronic components; and the provision of such a machine which is economical.
In general, a dynamoelectric machine of the present invention is connectable to an adjacent part while being simultaneously protected from moisture or contaminants.
The machine comprises a casing having a hollow interior defining a housing and a longitudinal axis.
An endshield is positioned generally at an end of the casing and mounts at least one electrical component used in operation of the machine.
The endshield has a wall projecting in a longitudinal direction and further has at least two openings for receiving fasteners to connect the machine to the adjacent part.
The at least two openings define respective fastening locations on the endshield.
A cover is removably mounted on the endshield and defines an enclosure to protect the at least one electrical component.
The cover is configured for an overlapping fit with at least a portion of the wall of the endshield to prevent passage of moisture or contaminants into the enclosure.
The cover is further configured to avoid covering the at least two openings when mounted on the endshield such that the fastener locations lie outside of the enclosure and are accessible for connecting the machine to the adjacent part while the cover remains mounted on the endshield.
In another aspect, a method according to the present invention protects a dynamoelectric machine from moisture or contaminants while connecting the machine to an adjacent part
