ABSTRACT:
This invention provides apparatus for reinforcing an end of a motor housing of a motor of the type having a minimum vertical dimension. The invention accomplishes this objective in one embodiment by extending two axially extending gussets, which normally terminate short of the ends of the stator housing, until they contact inside surfaces of the ends of the stator housing. A stiffening bar is added along the bottom of the ends of the stator housing between the two extended gussets to carry downward vibration forces from the rotor bearings of the motor through the end shields to mounting rails located adjacent the gussets. This improvement reduces vibration and shifts the natural vibrational resonant frequencies of the structure further away from expected vibrational excitation frequencies of the motor.
In another embodiment of the invention the end shield of the motor is provided with force transmission members disposed diagonally downwardly to a pair of mounting flange members which are engaged, upon assembly of the end shield into the housing with a pair of diagonally disposed gussets which are fastened directly to a pair of motor mounting rails, thus bypassing the motor housing in the path of support for dynamic forces generated during operation of the motor.
