Electric linear actuators are primarily powered by electricity. They typically utilize an electric motor to generate power, employing a transmission mechanism to convert the motor's rotary motion into the linear motion of the actuator rod.
The motors used are generally either DC or AC types. DC motors offer advantages such as easy speed control and high starting torque, making them suitable for applications requiring precise speed and torque regulation. Conversely, AC motors are characterized by simple construction, reliable operation, and low cost, making them common choices for applications where high precision is not a primary requirement.
Inside the actuator, the motor connects to the rod via transmission components such as couplings or gearboxes. When the motor starts, it drives the transmission mechanism, thereby extending or retracting the rod. Precise control over the actuator's movement speed and direction is achieved by regulating the motor's rotational speed and direction.
Additionally, some electric linear actuators are equipped with a battery backup to ensure continued operation during power outages. Overall, the use of electricity as a power source offers advantages such as convenience, efficiency, and controllability, leading to the widespread application of electric linear actuators across various types of machinery and automation systems.
