What type of motor is a shunt DC motor classified as?

A shunt DC motor is classified as a DC motor because it operates on direct current (DC) electricity. In this type of motor, the field winding is connected in parallel (or shunt) with the armature winding. This configuration allows the motor to maintain a relatively constant speed under varying load conditions, which is a characteristic behavior of DC motors.

Shunt DC motors are particularly known for their ability to provide smooth and consistent torque, making them suitable for applications where speed regulation is crucial. This type of motor allows for easy speed control through voltage adjustment, making it versatile for various applications in industrial and commercial settings.

The other types of motors mentioned are not relevant to shunt DC motors. AC motors operate on alternating current (AC), universal motors can run on both AC and DC but are typically designed for different operational characteristics, and induction motors are a type of AC motor that relies on electromagnetic induction to operate.
