Electric motors

Definition

Electric motors are devices that convert electrical energy into mechanical energy through electromagnetic interactions. They play a crucial role in robotics by providing the motion and force needed for various tasks, enabling robots to perform precise movements and operations. Understanding electric motors is essential for designing effective end-effectors and selecting appropriate components in robotic systems.

5 Must Know Facts For Your Next Test
