Where are DC motors used in everyday life?

In our daily life, they are used in printers, fuel pumps, and electric vehicles. While in spacecraft applications, they are used in solar airplane, electric aircraft, and propulsion systems.

How do you tell the difference between AC and DC motors?

In AC motors, the armature is stationary while the magnetic field rotates. In DC motors, the armature rotates while the magnetic field remains stationary. In AC motors, three input terminals (RYB) is present. In DC motors, two input terminals (positive and negative) are present.

How can you tell the difference between AC and DC motors?

The most obvious difference is the type of current each motor turns into energy, alternating current in the case of AC motors, and direct current in the case of DC motors. AC motors are known for their increased power output and efficiency, while DC motors are prized for their speed control and output range.
