Detailed Explanations
Actuators
Actuators are essential components in electromechanical systems, converting electrical energy into mechanical action. Common types include linear actuators, which produce straight-line motion, and rotary actuators, which produce rotational motion.
Electric Motors
Electric motors, both AC and DC types, are widely used in various applications, from industrial machinery to household appliances. They operate on the principle of electromagnetic induction, where a current-carrying conductor placed in a magnetic field experiences a force.
Mathematical Models
Electromechanical systems often rely on complex mathematical models to predict their behavior. For example, the performance of an electric motor can be described using differential equations that account for electrical resistance, inductance, and mechanical inertia.
