PERMANENT MAGNET DIRECT DRIVE TOP DRIVE

机译:永磁直驱顶驱

摘要

A drive system (40) for a drilling has a housing (42) with an interior chamber (60), a stator (62) positioned within the interior chamber (60), a rotor (64) positioned in interior of the stator (62) and within in the interior chamber (60) of the housing (42), and a drive plate (66) affixed to the rotor (64). The rotor (64) has a plurality of permanent magnets in spaced relation around a periphery of the rotor. The stator (62) has a plurality of windings extending in spaced relation around an interior diameter of the stator so as to as be cooperative with the plurality of permanent magnets. The drive plate (66) has an interior passageway suitable for joining to a stem of the drill string.
