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:
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.

US Classification:
310216009, 29596
Abstract:
An electric machine stationary assembly is described. The stationary assembly includes a plurality of stacked laminations each comprising a first end and a second end. The stationary assembly also includes a mechanically deformable first fastening feature positioned at the first end of each lamination. The stationary assembly also includes a second fastening feature positioned at the second end of each lamination and configured to cooperate with the first fastening feature to couple the first end to the second end.

US Classification:
310 90, 2989807
Abstract:
An electric machine includes a housing, a bearing and a securing device. The housing defines a bearing seat and a support surface. The bearing cooperates with the bearing seat and defines a bearing clamping surface. The securing device is connected to the housing and includes a fastener and a member defining a member clamping surface. The member and the fastener secure the bearing to the housing. The securing device has a first position for assembly of the bearing into the bearing seat and a second position for constraining the bearing in the housing. The member clamping surface overlies the bearing clamping surface when the member is in the second position. The member provides continuous movement from the first position to the second position. The support surface engages the member when the member is in the second position.
Electrical Connector With A Releasable Load-Control Element For Multi-Connectable Loads

International Classification:
H02K 1100 H01K 2900
US Classification:
310 71
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.
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. Stops or tabs located on both sides of the head prevent the fastener from rotating once it is in place and the fastener is secured in place with a preload thereon by several different constructions which draw the fastener outwardly to force the inner end of the head against the outer bearing race and the outer end of the head against the spaced seat. The fastener may be internally threaded and receive a screw with a head assembled over a washer to secure the screw head and washer to the outboard side of the abutment when threaded into the fastener. The fastener may include a threaded shaft to receive a nut which abuts against the outboard side of the abutment.
