Electric Actuators

Electric actuators convert electrical energy into mechanical motion, providing precise and controlled linear or rotary movement. They are widely used in various industrial applications due to their ability to offer precise positioning, high efficiency, and reliable performance.

These actuators are telescopic and use a push tube using either a lead screw, ball screw or roller screw. They are complete with a basic electric motor, (typically 24v DC or 12v DC, but AC versions are also available) and gear to provide a fixed choice of speed and force. They usually have strokes in the 50mm – 700mm range, with forces from 50N to 500kN (from high performance versions). Electric actuators are used where the duty cycle is typically in the 10-25% range. ACORN offers a full range of AC and DC electric actuators and accessories.

What types of electric actuators are available?

Electric actuator

Electric actuators come in several types, including:

  • Linear Electric Actuators: Convert rotational motion into linear motion, suitable for applications requiring precise linear positioning.
  • Rotary Electric Actuators: Provide controlled rotary motion, ideal for applications requiring precise angular positioning.
  • Stepper Motor Actuators: Use stepper motors to provide precise and incremental motion, making them ideal for applications requiring high precision and repeatability.
  • Servo Motor Actuators: Use servo motors to provide precise and controlled motion, suitable for applications requiring high accuracy and dynamic response.

Lifting columns, or lifting pillars, also combine an electric actuator with specially machined and assembled pillar tubes. These offer high bending load capability with a compact design.

If you need to program the movement, control and speed/acceleration of an actuator, or you require 100% duty, then you will need a high-performance actuator.
