Abstract: An explosion proof motor including a stationary assembly and a rotatable assembly is described. The stationary assembly includes a stator that defines a stator bore. The rotatable assembly includes a rotor and a rotor shaft extending substantially axially through the stator bore. The explosion proof motor includes a frame configured to at least partially surround the stator. The frame defines an interior and an exterior of the motor. The explosion proof motor also includes at least one end shield positioned at an end of the frame and a bearing cap positioned proximate to the interior side of the end shield. The explosion proof motor also includes a flame path gap defined between the end shield and the bearing cap. The flame path gap includes at least one section that extends substantially parallel to the rotor shaft.

Abstract: A motor that includes a motor frame, an end-bell assembly, a stator assembly, and filling material is described. The stator assembly is placed within the frame such that at least one open area is defined between an inner diameter of the stator assembly and an inner diameter of the motor frame. The at least one end-bell assembly is attached to the motor frame, forming an inside area adjacent the motor frame and the stator assembly. The motor also includes a material configured to fill the at least one open area and the inside area of the at least one end-bell assembly for the purpose of sealing the stator assembly and the inside area associated with the at least one end-bell assembly. The material assists in a bonding and attachment between any two or more of the stator assembly, the motor frame, and the at least one end-bell assembly.

Abstract: A universal motor connector unit is usable with different three phase and single phase motors for connecting the motors to different incoming voltages. The connector has a motor-mounted connector unit with 15 socket terminals and contacts in a fixed 3.times.5 matrix array. A complementing plug-in connector unit has pin contacts in a similar matrix and with U-shaped connections between the pin contacts. In a three phase connector, 12 pin contacts are in a 3.times.4 matrix. The plug-in unit in one orientation establishes a first winding connection for one voltage and when rotated 180.degree., a second voltage. The connector may also be used to change direction of rotation rather than voltage selection. For a single phase motor, the socket connector is the same as for the three phase motor. The plug-in unit is formed with separate plug-in elements; one is provided for voltage selection and a second for rotation selection.

Abstract: A bearing locking construction for dynamoelectric machines having a bearing locking assembly which can be located in place after an electric motor or other dynamoelectric machine is completely assembled. The construction includes a bearing housing which has at least a pair of abutments located on opposite sides of the motor shaft which house a fastening means for locating the bearing lock and securing the bearing in its seat and consists of fasteners which are assembled through the abutments from the outboard side of the motor and has a large T-shaped head rotated by rotation of the fastener to overlap the bearing on one side and an axially spaced seat on the opposite side.
