发明名称 DOWNHOLE LOAD SHARING MOTOR ASSEMBLY
摘要 A motor assembly of multiple motors for use in driving a shared downhole load within a well. In particular, the assembly may employ substantially constant adjustable speed motors. These may include permanent magnet synchronous machine motors. The motors may be configured to operate at given speeds that may be downwardly adjusted depending on the amount of torque output independently exhibited by the individual motors. In this manner, a significant divergence in torque output between the motors may be avoided so as to ensure substantial load sharing between all of the motors of the assembly.
