What are EMG Electrohydraulic Thrusters?
EMG electrohydraulic thrusters are a type of actuator that converts electrical signals into hydraulic energy to control the movement of a marine vessel. These thrusters are typically used to control a vessel’s steering, propulsion, and other movements, such as lifting, lowering, or tilting.
How do EMG Electrohydraulic Thrusters work?
EMG electrohydraulic thrusters work by using an electric motor to drive a hydraulic pump. The hydraulic pump, in turn, drives a hydraulic cylinder or motor, which provides the force required to move the vessel. The electric motor and hydraulic pump are controlled by an electronic control system that receives signals from the vessel’s control system.
When a signal is sent to the thruster’s control system, the electronic control system activates the electric motor, which drives the hydraulic pump. The hydraulic pump then pumps hydraulic fluid from a reservoir to the hydraulic cylinder or motor, which generates the force required to move the vessel.
Advantages of EMG Electrohydraulic Thrusters
One of the main advantages of EMG electrohydraulic thrusters is their ability to provide precise and accurate control over a vessel’s movement. Because an electric motor drives the thrusters, they can be controlled with great accuracy, allowing for precise movements and adjustments.
Another advantage of EMG electrohydraulic thrusters is their reliability and durability. These thrusters are designed to withstand the harsh marine environment and can operate for long periods of time without requiring maintenance.
Finally, EMG electrohydraulic thrusters are energy-efficient. Because they use electric motors to drive hydraulic pumps, they can be powered by the vessel’s electrical system, which is typically more efficient than a hydraulic system powered by a separate engine.
EMG Electrohydraulic Thrusters in Maritime Applications
EMG electrohydraulic thrusters are critical in the marine and offshore industries, providing precise and reliable control over a vessel’s movement. While they do have some disadvantages, their ability to operate in harsh marine environments and provide precise control makes them a popular choice for marine vessel applications.

EMG Conveyor Braking Systems
EMG conveyor braking systems are an essential component of conveyor systems used in various industries, including mining, manufacturing, and logistics. These braking systems are used to control the movement of conveyor belts and ensure the safety of workers and equipment.
EMG conveyor braking systems typically use electromagnetic brakes to control the movement of the conveyor belt. When the brake receives voltage or current, the coil is energized, creating a magnetic field. This field turns the coil into an electromagnet that creates magnetic lines of flux. The magnetic flux attracts the armature, which in turn applies pressure to the rotor, creating friction that stops the conveyor belt.

EMG Guide Rollers and Braking Systems
When designing EMG conveyor braking systems, it is important to consider factors such as the specifications of the conveyor system, the efficiency of the braking system, and the cost of the braking system.
To reduce costs, all conveyor system components, including structure, belts, and rollers, should be scrutinized for maximum efficiency and performance. The braking system should be selected to meet the specifications of each conveyor to ensure that the most cost-effective brakes and controls are optimized to match the system’s requirements precisely [2].
To ensure the smooth braking and security of conveyor systems, accurate design techniques should be adopted, and dynamic simulation methods should be used to research the braking performance of the belt conveyor. By comparing the dynamic performances of some models, researchers can determine the most effective braking systems for different conveyor systems.
In conclusion, EMG conveyor braking systems are crucial for the safety and efficiency of conveyor systems in various industries. Electromagnetic brakes, considering system specifications, and adopting accurate design techniques can help ensure the most effective and cost-efficient braking systems for each conveyor.
