CA 2270017
A high torque drivehead apparatus is provided for driving a downhole rotary pump. The drivehead utilizes a switched reluctance motor having a stator and frame secured to the wellhead. The motor's rotor is fitted with a concentric hollow drive shaft for accepting the rod string's polish rod. Further, the rotor is supported from the frame with thrust bearings for supporting the rod string. In operation, the drivehead provides consistent torque at a wide range of speeds including nearly zero rpm. Upon power failure, backspin of the rod string does not result in dangerous speed magnification at the drivehead and thus is not a threat to safety.
