Electric Actuators Articles
Electric actuators, also known as electric machines are electromechanical devices that convert electrical energy into mechanical torque. No oil is used which makes it a very clean type of actuator. This is usually enabled through the interaction of magnetic fields and current-carrying conductors to create force. In some cases, electric actuators can also be used as generators to convert mechanical energy into electrical energy.
