PWM speed control knob use method

PWM 1-2ms speed control knob.

It can be used to connect ESC signal lines to control brushless motors or underwater thrusters for operation.

If the ESC of the thruster/motor supports bidirectional, then the speed knob can control the thruster/motor to rotate clockwise or counterclockwise.
If the ESC of the thruster/motor supports only unidirectional, then it can only control one direction of rotation.

Pump jet propulsion for surfboards and go-karts

Posted by Fengyukun on

For surfboards, traditional propulsion methods often rely on the power of waves or human paddling, which has great limitations. The emergence of pump-jet propulsion has completely changed this situation.It is small and powerful, installed on a surfboard, like giving surfers a pair of flying wings. This propeller can provide stable and continuous power, allowing you to ride on the water even when the waves are small. Whether it is pursuing the ultimate challenge of speed or enjoying a leisurely water slide, pump-jet propulsion can meet the needs of different surfers.On a surfboard equipped with a pump-jet propulsion, it can accurately...

Working principle of jet pump propeller

Posted by Fengyukun on

The working principle of jet pump propulsion is mainly dependent on its internal working mechanism and the action of external water currents.These thrusters are usually mounted in the wake of the vehicle and are designed so that the contour lines of the rotor and stator are in line with the wake of the vehicle, thus effectively utilising the obstructed wake flow in the wake of the vehicle and improving propulsion efficiency.The working principle of the jet pump propeller is mainly divided into the jet suction principle and the thrust principle.Jet suction principle: the jet pump through the nozzle and the...
