How much energy does an actuator save compared to a traditional EHA?

Instead of establishing the mathematical model for the purpose of the dynamic analysis, a model of the developed actuator is built in AMESim software. The simulation results reveal that the system is able to save approximately 20% energy consumption compared with a traditional without energy recovery EHA.

What is an actuator & how does it work?

An actuator is a vital component of any physical system enabling movements by converting an energy source into another, primarily electrical, air, or hydraulic energy, into mechanical force [ 1, 2] to modify the current system’s state.

Why do solar tracking systems use electric actuators?

The first generation saw the use of hydraulic actuators, but hydraulic leaks and actuator pressure losses harm the effectiveness of solar tracking and cause heliostat oscillations causing rotation axis wear. Therefore, an electric actuator is used in the second generation due to efficient and reliable tracking control.

What is the role of actuators in solar systems?

Actuators play a significant role in solar tracking and cleaning, and the efficient use of electric actuators improves system efficiency. Table 3. Summary of actuator power consumption in different applications. 3. Actuators in Wind Applications

Are pneumatic actuators useful to control valves in the energy sector?

Motlagh et al. propose that pneumatic actuators are helpful to control valves in the energy sector, such as in power plants and the oil and gas industries [ 66 ]. The use of electric control-valve actuator technology allows for energy efficiency.

Can electrical actuators be used in renewable applications?

However, except for electrical ones, all actuators are restricted due to their size, complex auxiliary equipment, frequent need for maintenance, and sluggish environment in renewable applications. This brief review paper highlights some unique and significant research works on applying electrical actuators to renewable applications.
