An electric actuator is a mechanical device that converts electrical energy into mechanical motion to control or move a system. These actuators are widely used in industries like marine, robotics, space, aerospace industries and many more industries where the precise motion of an actuator is required.
Actuators are rapidly becoming the go to solution for precise motion control across high performance industries. Unlike traditional hydraulic and pneumatic systems, they deliver motion using only an electrical input, offering benefits in efficiency, control and maintenance. Here at Olsen Actuators & Drives we specialise in high performance electric actuators and custom motion solutions to match the customers’ needs for their specific applications, pushing the boundaries of what electric actuator’s can do.
At Olsen, the product range includes linear actuators, rotary actuators, roller-screw systems, and dedicated servo drives to power them. A great example is our roller screw linear actuators which use a threaded roller mechanism instead of the traditional ball and screw, enabling high dynamic load capacity, long life, and lower maintenance. What this means in practice is actuators are capable of forces up to hundreds of kilonewtons, travels up to metres in length, repeatability. We successfully supplied blade pitch and blade tilt actuators for the eVTOL VX4 aircraft by Vertical Aerospace. For this eVTOL application we delivered high-capacity roller screw actuators, custom drives and encoders enabling rapid pitch and tilt motion control in the aircraft’s flight motion.
Why choose electric actuators?
- Energy efficiency: Electric actuators only consume power when moving and avoid the continuous power losses that occur with hydraulic pumps or pneumatic compressors.
- Low maintenance & clean operation: No hydraulic fluid leaks, fewer components to service, and no hoses to route in tight spaces or complex environments.
- High precision & control: With integrated servo drives, position/force control, and feedback encoders, electric actuators can achieve very fine motion and repeatability ideal for robotics, aerospace, test rigs and more.
- Compact and weight savings: Especially important in aerospace, electric actuators allow dramatic weight/volume reduction versus hydraulic systems seen in our work on eVTOL and subsea systems.
In summary, electric actuators are increasingly being used for high-force applications due to their superior performance and efficiency over the traditional ball and screw, offering full control of motion and are fully programmable, making them the ideal for applications requiring precise control. Electric actuators can deliver forces of 225.5 Nm and higher making them suitable for extreme high-force and high-duty applications.
