🔍 Key Concepts

• Trace the mechanical linkage from the synchronizing (speed setting) motor through the friction clutch to the speeder spring and fuel control lever. • Think about how generator frequency and speed are adjusted when matching (synchronizing) to a bus. • Notice what parts of the diagram are labeled with synchronizer (speed) adjustment and how they affect the terminal shaft and load.

💭 Think About

• When paralleling generators, what variable must be finely adjusted so two machines can be synchronized: shaft torque, shaft speed, or lamp power? • If the synchronizing motor turns, which governor component does it move, and how does that change the engine’s operation? • Which choice best matches a device whose job is to slowly trim speed so the generator can be matched to another unit from a control panel?

✅ Before You Answer

• Verify which component in the illustration is directly connected to the speeder spring / speed-setting mechanism rather than to the terminal shaft itself. • Check whether the synchronizing motor is shown supplying any electrical power output or just providing mechanical motion to an adjustment linkage. • Confirm which answer choice describes a remote, automatic, or fine speed-trimming function rather than basic governor or generator operation.
