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

The correct interpretation is that shunt motors are characterized by their field winding being connected in parallel with the armature winding. This design allows for a relatively constant speed under varying load conditions because the field strength remains stable. Typically, shunt motors are used in applications that require consistent speed, such as in lathes and other machinery where precision is critical.

In the context of the schematic, identifying shunt motors involves looking for indications that the field winding is wired in parallel with the armature. Features such as a nearly constant speed across different loads and the motor's ability to produce a high starting torque further support the classification as shunt motors.

If the schematic included other configurations, such as series motors with their field windings in series with the armature or induction motors, the characteristics would differ significantly in terms of speed regulation and torque behavior, influencing the potential applications and performance under load. Thus, if the schematic aligns with the properties described, it justifies identifying the motor type as shunt.
