Motors convert electrical energy into mechanical energy. Actuators, which can include motors, also encompass hydraulic or pneumatic systems. Actuators are used to control or move mechanisms. Solenoids often function as switches or linear actuators, using a magnetic field to move a plunger or lever when energized. Drivers control the operation of motors, actuators, or solenoids by providing the necessary voltage, current, and signal shaping to ensure these devices operate correctly and efficiently.The relationship between these devices lies in their complementary roles within systems requiring controlled mechanical or electrical movement.
