The neutral stop signal is its unlocking signal
Using a 50Hz signal, the signal period is 20ms.
The percentage in the instructions refers to the percentage of the PWM control pulse width, not the actual duty cycle of the PWM signal (it is easy to misunderstand here).

A lot of researchers who want to control the operation of the thruster with a microcontroller to find a lot of information on the Internet, but found that a lot of them are not written very clearly, APISQUEEN roughly record how to solve.I hope you can exchange experience in the comments section, can help more people.We buy the ESC may be different, but the overall control idea is the same, so I believe you can certainly achieve your goal after reading this article. PWM signal:(1) PWM wave control (generally speaking ESCs are controlled by PWM wave at 50Hz, that is...

Water jet propulsion is a kind of thruster which uses the reaction force generated by the water jet to drive the ship forward. By the pump body, runner, water inlet and nozzle and other components, and can change the direction of water jet through the nozzle to achieve the ship's manoeuvrability, good manoeuvrability, especially for shallow waterways, water jet thruster has a good adaptability.

The brushless motor/thruster cannot be connected directly to the power supply. The phase sequence is controlled by the controller (ESC) in order to ensure the motor/propeller operates properly and can make the motor/propeller work more efficiently. If you need to use a brushless motor, please make sure to pay attention to the correct operation method to ensure the normal use and long life of the motor.

Propellers for boats are usually of two types, left-hand and right-hand, known as CW and CCW respectively. CW is an abbreviation for Clockwise, indicating a clockwise rotating propeller, also known as a right-hand propeller. When a ship's propeller is rotating, the leading edge of the propeller blade is to the right and the trailing edge is to the left when viewed from the side, propelling the water in the same direction as the rotation. The right-hand propeller is usually mounted on the left side of the ship, i.e. the port side of the ship. CCW stands for Counterclockwise and indicates...
