A direct current (DC) shunt motor has the field coils and armature connected in which configuration?

A direct current (DC) shunt motor is characterized by the configuration of its field coils and armature, which are connected in parallel. In this configuration, the field coils receive a constant voltage from the same source as the armature, allowing them to generate a magnetic field that is relatively independent of the armature current.

This parallel connection allows for a more stable operation under varying load conditions because the field strength remains fairly consistent. As the armature current increases with load, the voltage across the field coils does not significantly drop, maintaining the motor's performance and preventing a drastic reduction in speed. This is distinct from a series motor, where the field coils are connected in series with the armature, resulting in a field strength that varies with load and can lead to instability.

Understanding the characteristics of the shunt motor configuration is essential for proper operation and ensures that the motor can handle changes in load while maintaining efficiency and performance.
