Electromechanical energy conversion
Electromechanical actuators for robotics and positioning

The electromechanical actuator is one of the main links in the system in which it is integrated, converting the energy required to perform a mechanical action from a primary electrical energy source. This action can take a large number of possible forms, from the elementary, one-dimensional displacement of a moving body (an electromagnet-type actuator, for example), to the multi-dimensional control of a complex movement involving the simultaneous management of several degrees of freedom (a rotoid actuator for a medical prosthesis, for example). To this end, the electromechanical actuator is generally associated with a sensor device (position, speed, force, etc.). The available information can then be processed by an...
