Electric Actuator Manufacturers and Suppliers

Many electric actuators are designed with easy-to-use interfaces. This innovation is partly because the actuators are engineered for different programming cycles and procedures. Enhanced controlling is ideal for conditions that require flexibility such as fast paced production environments. Manufacturers and consumers are realizing electric actuators are capable of replicating the same functions as of hydraulic and pneumatic actuators. Electric actuators also save more money in the long run due to less clean up costs that are normally associated with hydraulic fluid spills.

Electric actuators are becoming more ideal for medical applications that require precision and reliability. Newer models have a smaller structure that allow for easier assimilation into existing systems but there is no compromise for performance. There are also extra benefits due to the combined capabilities; the user can trust a single source when performing those crucial medical applications. As time becomes a premium it is essential that components are going to function at optimum efficiency.

The basic construction of an electric actuator consists of an electric motor, a screw, a nut and possibly gears if the electric motor is a small motor. In an electric actuator, it is the nut that provides the translation from electrical motion to mechanical motion when it rotates along the screw, moving forward instead of rotating along with the screw. Rotary electric actuators rotate from open to close using butterfly, ball, and plug valves. With the use of rotary electric actuators, the electromagnetic power from the motor causes the components to rotate, allowing for numerous stops during each stroke. Either a circular shaft or a table can be used as the rotational element. The actuator torque refers to the power that causes the rotation, while the full range of motion can be either nominal, quarter-turn, or multi-turn. Linear electric actuators, in contrast, open and close using pinch, globe, diaphragm, gate, or angle valves. Linear electric actuators are often used when tight tolerances are required. These electric actuators use an ACME screw assembly or motor-driven ball screw to supply linear motion. Within linear electric actuators, the load is connected to the end of a screw that is belt or gear driven.

Electric actuators are divided into two different types: rotary and linear. When selecting an electric rotary actuator, important factors to consider include actuator torque and range of motion. Important factors to consider when selecting linear electric actuators include the number of turns, actuating force, and the length of the valve stem stroke. Both rotary and linear electric actuators are often used in a variety of applications and industries such as: automotive, for use in power door lock systems and air conditioning systems; industrial manufacturing, to be utilized as control components in many industrial devices; agriculture, for use in farming machinery such as combine harvesters and fertilizer spreaders; and power generation, in which they are particularly utilized for green technologies such as wind turbine construction.

There have been a number of advancements in the electric actuation industry. Many companies design newer actuators to be utilized for multiple and diverse applications. Consumers look for high performance and consistent functionality. Manufacturers have been combining the features of motors and actuators which results in greater customer satisfaction based on higher usability of control, mobility, and sustainability. As applications become more demanding, the actuator industry has been upgrading to keep pace, utilizing more intricate components and processes. Another reason electric actuators are targets for innovation has to do with the growing concerns of operational processes becoming more environmentally friendly.
