Electric motors can be widely classified into 3 types: AC, DC, and universal. As the name suggests, an AC motor runs with AC power and a DC motor runs with DC power. Universal motors can run with both AC and DC power. Examples of AC motors are AC induction motors and squirrel cage motors. They are further classified as single-phase and multi-phase motors. Examples of DC motors include Brushed DC motors, Brushless DC motors (BLDC), and stepper motors.
