Abstract

The invention, which relates to the technical field of deep well pumps, discloses an electromechanical integrated high-speed asynchronous submersible electric pump comprising a motor connected with apump body. The motor includes a housing, a stator winding fixed on the inner wall of the housing, a rotor, and a controller circuit board arranged inside the housing, wherein the rotor is in rotationconnection with the housing and is opposite to the stator winding. A cable of the motor passes through the stator winding and is connected with the controller circuit board electrically; and the controller circuit board is arranged below the stator winding. According to the invention, the integrated design of the controller circuit board and the motor is realized; and the control and feedback effects of the motor are optimized. On the basis of the slot hole design, a tank filling rate of the coil is not affected and the energy utilization rate of the motor is improved; and the practicability of the deep well pump is further improved. Meanwhile, the motor is split into a motor cylinder and a controller cylinder, so that the motor is dismounted or mounted conveniently and rapidly.

Description

technical field [0001] The invention relates to the technical field of deep well pumps, in particular to a mechatronic high-speed asynchronous submersible electric pump. Background technique [0002] At present, the Chinese patent with the notification number CN206135587U discloses a permanent magnet brushless DC motor for deep well pumps, including a stator and a rotating shaft located in the casing of the deep well pump, and several circumferentially arranged installation grooves are opened on the outer peripheral wall of the rotating shaft , the inside of the mounting groove is mounted with a tile-shaped permanent magnet. [0003] Existing permanent magnets are generally made of rare earths, and the price of rare earths is relatively high, which greatly increases the production cost of the permanent magnet brushless DC motor for deep well pumps. [0004] At the same time, during the use of the permanent magnet brushless DC motor for deep well pumps, the magnetism of the ...
