Sealed drive for a rotating sucker rod

A drive assembly for powering a rotating rod string in a well having a surface wellhead, comprising:

• a torque conveying housing containing a radially outer member supporting a plurality of outer member magnets, the outer member rotated by a motor;
• a radially inner member supporting a plurality of inner member magnets and rotatable within the outer magnets, magnetic forces between the plurality of outer member magnets and the plurality of inner member magnets rotating the inner member magnets and the radially inner member when the motor rotates the outer member;
• and
• the radially inner member connected to the sucker rod for rotating the sucker rod when the radially inner member rotates.

• a torque conveying housing containing a radially outer member supporting a plurality of outer member magnets, the outer member rotated by a motor within the torque conveying housing;
• a radially inner member supporting a plurality of inner member magnets, magnetic forces between the plurality of outer member magnets and the plurality of inner member magnets rotating the inner member magnets and the radially inner member when the motor rotates the outer member;
• a radially inner member being rotationally connected to the sucker rod for rotating the sucker rod;
• and
• a pressure bearing housing above the torque conveying housing for sealing fluid pressure within the wellhead.
