Embodiment Construction

[0020] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0021] The composition of the three-phase DC brushless deep-water motor includes: 1 main shaft, 2 bearings, 3 front cover, 4 water inlet, 5 power connector, 6 water outlet, 7 fixed rod, 8 rear cover, 9 fixed plate, 10 magnet Steel rotor disc, 11 casings, 12 stator coil discs. The composition of the motor part includes a main shaft 1 , a magnetic steel rotor disk 10 , and a coil stator disk 12 . The magnetic steel rotor disk has three pieces, and the stator coil disk has two pieces. The magnetic steel rotor disk and the stator coil disk are arranged alternately. The three magnetic steel rotor disks 10 are all fixedly connected to the main shaft. The fixed rod 7 connects the fixed plate 9 together, the fixed plate is connected with the rear cover 8 , and the rear cover is installed on the casing 11 . The front cover 3 is installed at the other end of the casing.

Abstract

The invention provides a three-phase direct-current brushless deep-water motor, comprising a motor housing composed of a front shroud, a back shroud and a housing, wherein a main shaft is installed on the front shroud and the back shroud via a bearing, magnetic steel rotor disks and coil stator disks are installed inside the motor housing, a water inlet and a water outlet are installed on the housing, the magnetic steel rotor disks are fixedly installed on the main shaft, the coil stator disks are fixed on the motor housing, and the magnetic steel rotor disks and the coil stator disks are in alternative arrangement. The three-phase direct-current brushless deep-water motor in the invention has simple structure, easy processing and low cost, and the biggest feature is that a waterproof housing does not be needed. The internal structure of the motor and the structure of the existing submersible motor are completely different. The invention can be applied to small submarine, submarine mine, diving pusher and other deepwater machines.

Description

(1) Technical field [0001] The invention relates to a motor, in particular to a deep water motor. (2) Background technology [0002] There are many public reports on deep-water motors. For example, the Chinese patent application number is 200680010784.X, and the name is "submersible motor"; the application number is 02121599.5, and the name is "single-phase long-life submersible motor". . Above existing deep-water motor or submersible motor just has done processing motor itself in waterproof aspect and does not have much transformation, once leaks air or water, motor just damages and can not reach the requirement of long-term work under deep water. The submersible motor only changes the waterproof performance of the motor shell, and its internal structure is not much different from that of ordinary motors, and there is no improvement in the internal heat dissipation of the motor. Complicated in processing and manufacturing technology does not have economical and practical ...
