The utility model belongs to the field of the non-beam pumping unit, specifically relating to a non-beam pumping unit driven by a biaxial motor. The non-beam pumping unit driven by a biaxial comprises a base, a tower body and a drive mechanism. The drive mechanism is mounted on the platform, comprising a biaxial motor, a large roller, a small roller, a belt and a counterweight device. The two ends of the biaxial motor are respectively connected with the two ends of the large roller through the chain and the sprocket respectively. The utility model uses the biaxial motor instead of the uniaxial motor which in the prior art, the motor and the large roller on both sides are in balance, and solves the problem of partial grinding effectively and prolongs the service life of the bearing.
