Abstract
An electric-motor/hydraulic-pump assembly in which an electric motor has a motor housing and a motor drive shaft, and a hydraulic pump is mounted directly to one end of the motor housing and internally coupled to the shaft to form a unitary assembly in which vibration generated by operation of the pump is transmitted to the motor housing. Support feet are affixed to the motor housing for mounting the motor/pump assembly to underlying support structure, and sound deadening ferrules are interposed between the motor housing and the support feet to inhibit transmission of structureborne noise from the motor housing to the support structure. The motor and pump are surrounded by a sound enclosure to inhibit radiation of airborne noise into the surround atmosphere. Fluid is drawn through an inlet in the sound enclosure and through the motor housing to cool the motor, and then pumped to a fluid outlet in the enclosure.
