[0028] In order to facilitate the wiring of the marine brake, the terminal box 7 is arranged above the stator body 11, thereby avoiding the trouble and protection of external wiring.

[0029] When an emergency situation such as power system failure or failure of the stator coil 6 occurs, the manual release function is particularly important, the handle 8 is simply pulled backward to quickly realize the manual release of the brake, thereby ensuring that the ship can quickly resume driving or perform necessary operations in an emergency situation, so that the operator can quickly and accurately release the brake in an emergency situation, thereby avoiding the occurrence of dangerous situations such as loss of control or collision of the ship due to failure of the brake to be released in time, and significantly improving the safety of ship operation.

At this time, there is a certain air gap between the armature 4 and the stator body 11 to ensure that the brake is in the braking state when there is no current passing through. When the brake needs to be released, direct current is supplied to the stator coil 6, and the magnetic field generated by the stator coil 6 attracts the armature 4, compresses the spring 5 and moves towards the stator body 11, thereby releasing the braking state of the rotor 2 and making the brake in the released state. The brake can quickly generate a braking torque to achieve reliable braking, ensuring that the ship can quickly respond when it needs to stop or slow down, and achieving quick release of the braking state.
