Abstract

The invention discloses a three-phase asynchronous motor with ultrahigh efficiency and high torque. The three-phase asynchronous motor comprises a base, a fixed block and a shell; the fixed block is arranged at an upper side of the base, the shell is arranged at the upper side of the fixed block, a bearing outer cover is arranged at one side of the shell, and an end cover is arranged in the bearing outer cover; a bearing inner cover is arranged at one side, far away from the bearing outer cover, of the end cover, and a rotor is arranged in the bearing inner cover. The motor disclosed by the invention has the advantages that the start current can be reduced by 2-10% by utilizing a skin effect, the impact on the motor by the peak current and surge current of the surrounding grid can be reduced, the variable loss and invariable loss of the motor can be realized, and the motor efficiency can be improved; by arranging the novel alloy cast-aluminum rotor and motor optimization design, the motor has a flexible mechanical feature, and the motor can be adapted to a demand of the oil production technology of the petroleum industry preferably.

Description

technical field [0001] The invention relates to the field of electric motors, in particular to a three-phase asynchronous motor with ultra-high efficiency and high torque. Background technique [0002] Three-phase asynchronous motor is a kind of induction motor. It is a type of motor powered by 380V three-phase AC current at the same time. Since the rotor and stator of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a rotation speed. The difference rate, so it is called a three-phase asynchronous motor. The rotor speed of the three-phase asynchronous motor is lower than that of the rotating magnetic field. The relative motion between the rotor winding and the magnetic field generates electromotive force and current, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion. The existing high-efficiency motors cannot meet the needs of high starting torque and soft mechanical charact...
