foreword First of all, if an unmanned ship is to be unmanned, it must be able to run by itself; to run by itself, it must know its own GPS coordinates and its own attitude. Just like an airplane, it is possible that the value of an airplane......2022-06-16
The brushless DC motor (BLDC) is a new type of mechatronic motor that has emerged with the development of semiconductor electronics. It is a product of the combination of modern electronics (including electronic power and microelectronics),......2021-11-27
As you have probably already tested, a normal model airplane brushless motor is perfectly capable of operating underwater. However, when tested in simulated corrosive seawater, it becomes clear that such brushless motors with untreated expo......2021-11-27
1. Brush motor working principle The brush motor is the first type of motor that we have come across. The main structure of a brushed motor is a stator + rotor + brushes, which obtains its rotational torque through a rotating magnetic field......2021-11-27
Brushless and sensorless control is extremely widespread in practice and has been studied for a long time in particular. Its control difficulties are mainly twofold. Firstly, the starting of the motor. Secondly, the detection of the rotor p......2021-11-15
Brushless DC motors have no brushes or commutators, hence their name. It consists of a motor body and a drive, and is a typical mechatronic product. As a newcomer to the motor industry, brushless DC motors have not had a long history in Chi......2021-11-15
1. Brushless DC motors for automobiles A car usually includes dozens to hundreds of motors inside. With the rapid development of cars in the direction of energy saving and environmental protection, brushless DC motors have a very good appli......2021-11-15
From the point of view of the physics of carrier propulsion, an unmanned underwater vehicle (UUV) is little different from a ski boat or a tanker. It uses a navigator-thruster-drive system model, which converts drive energy into thrust thro......2021-10-27
Many divers are aware of underwater thrusters, which offer a new form of recreation, greatly increasing the range and speed of people in the water and increasing the recreational aspect of underwater activities. In addition to this, underwa......2021-10-27
Propellers (Propellers) are devices that convert any form of energy into mechanical energy. Thrust is generated by rotating blades or jets of air (water). It can be used to drive a vehicle forward or as a source of power for other devices s......2021-10-27
