According to the schematic, which type of motors are shown?

The motors depicted in the schematic are classified as shunt motors due to their unique wiring configuration. In a shunt motor, the field windings are connected in parallel, or "shunt," with the armature windings. This design allows for consistent speed regulation under varying load conditions since the field current remains relatively constant regardless of the load changes.

Shunt motors are commonly used in applications requiring good speed control and torque stability. They provide high starting torque and maintain a more constant speed compared to series motors, which change speed significantly with load variations. Unlike synchronous and induction motors, shunt motors rely on the interaction between the fixed field and rotating armature, giving them distinct operational characteristics that fit specific applications.

The other types of motors have different winding configurations and operational principles, which do not align with the characteristics displayed in the schematic. Understanding these distinctions is crucial for identifying motor types and their appropriate applications in various contexts.
