Electric Motors
What Is an Electric Motor?
An electric motor is an electromechanical device that converts electrical energy into mechanical motion using electromagnetic principles. By generating a magnetic field, electric motors create rotational or linear movement that powers everything from household appliances to heavy-duty industrial equipment.
Electric motors are available in a wide range of power ratings, sizes, and configurations, making them a core component of modern industrial systems.
