Abstract

A direct drive motor and swivel assembly is provided. The assembly comprises a motor with a modified motor shaft extending through the motor. The motor shaft has a longitudinal passageway extending therethrough and a first end which is disposed outside of the motor and a second end opposite thereto. The swivel shaft of a swivel is axially aligned with the first end of the motor shaft and coupled thereto at a point outside of the motor such that the motor shaft passageway and swivel shaft passageway are in communication. The second end of the motor shaft may be connected to nozzles such that fluid flowing through the swivel housing into the swivel shaft and motor shaft will exit the second end of the motor shaft and flow through nozzles.
