Abstract
In one aspect, a downhole assembly has a downhole tool string component with a bore adapted to accommodate drilling mud. A fluid barrier is disposed within the bore and has a cylindrical portion substantially aligned with the bore. A drive shaft is sealed within and substantially coaxial with the cylindrical portion and has a first magnet disposed on its outer surface. A turbine assembly is disposed around the cylindrical portion of the fluid barrier and has an inner diameter and outer surface. The outer surface of the turbine assembly has a plurality of turbine blades. The inner diameter of the turbine assembly has a second magnet disposed within a region defined by the turbine blades and is in magnetic communication with the first magnet of the drive shaft, wherein when the drilling mud engages the turbine blades the first and second magnets rotate the drive shaft with the turbine assembly.
