Abstract

The invention provides a brushless permanent magnet direct-current motor. The brushless permanent magnet direct-current motor comprises a cylindrical motor body and a protection mechanism, wherein the protection mechanism is arranged on the outer side of the body. According to the invention, longitudinal impact force is converted into transverse thrust through arrangement of an anti-collision plate and a first buffer structure and cooperation of a longitudinal rod and a transverse rod, and meanwhile, in consideration of an underwater environment, the transverse rod pushes to enable a drainage hole to drain water, and the water is used for buffering impact force to form a first-layer collision avoidance; meanwhile, a second buffer structure is arranged in the middle of a frame, buffer rods can convert longitudinal thrust into thrust of push rods so as to form second-layer collision avoidance; and thus, since the characteristics of the underwater environment are combined with collision avoidance buffer, impact force can be effectively decomposed, and the motor is protected.

Description

technical field [0001] The invention relates to a structure of a brushless permanent magnet DC motor. Background technique [0002] Brushless permanent magnet DC motor has the characteristics of low failure rate, high efficiency and small size, and has been widely used in various fields. Some underwater environment operations have also begun to use brushless permanent magnet DC motors. However, usually the underwater environment is complex, and unpredictable impacts or injuries may occur, thereby causing damage to the use of the motor. The characteristics of the underwater environment, to some extent, also limit the use of brushless permanent magnet DC motors. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a brushless permanent magnet DC motor, which is provided with an anti-collision protection mechanism, which can effectively protect the motor. [0004] The present invention is realized in the follow...
