Motors - AC, DCAC and DC motors are types of electric motors that are used to convert electrical energy into mechanical movement. AC motors are powered by alternating current (AC), while DC motors are powered by direct current (DC). AC motors are more common and are used in a wide range of applications, from small household appliances to large industrial machinery. DC motors are typically smaller and are used in applications where precise control of the motor's speed and torque is required. Both AC and DC motors can be further classified based on their construction and operating principles, such as induction motors, servo motors, and stepper motors.
