Thermistors and resistance temperature detectors (RDTs, type Pt100 as standard) are devices used to detect abnormal overheating of one or more components, which often precedes damage to the windings, so as to protect the alternator from damage. These devices have resistance values that change as their temperature changes. They are embedded within the windings or on the bearing cases to measure the temperatures at those points. The temperature devices are wired into circuits that can trip an alarm or force a shutdown of the generator if the components are overheating.
To ensure the consistent operation and long-term lifespan of your alternator it is essential you buy genuine.

The alternators have two types of construction form: the one bearing form and the two bearings form.
Each of these defines the type of coupling to engine, and the mode of motion transmission from the prime mover shaft to the alternator rotor.
The one bearing (built with a single bearing) are coupled to the engine via a series of discs connected to the engine flywheel. The coupling adaptor allows alignment and rigid coupling between the static engine and alternator components.

The coupling adaptor allows alignment and rigid coupling between the static engine and alternator components.
In two bearings alternators (built with two or more bearings), the coupling between the crankshaft and the alternator shaft takes place via a rigid hub blocked onto the alternator shaft; a rubber elastic coupling is applied to the hub, which, coupled to the crown of the engine flywheel, transmits its motion. Also for this type of alternator it is necessary to install a couplong adaptor between the engine and the alternator for the correct alignment and rigid coupling of the components.

Bearings are a critical part of generator operation. The bearings are the point of contact between the stationary generator frame and the moving rotor. There are different types of bearing used in generator construction; bearing selection is based on the application of the generator and required performances.
The bearings used by STAMFORD® | AvK® for their alternators can be divided into the following three types:
Alternator 30.000 hours / 5 years service-kits
For the 30.000 hours extended service interval the Manufacturer recommend replacing several components in order to optimise the alternator’s performance. The maintenance plan also suggests replacement every 5 years for emergency/occasional alternators.
To better optimize the maintenance activity, the Manufacturer has created these spare parts kits which include all the components it suggests replacing.
The mentioned kits are available for all the Stamford’s alternators and usually each of them includes following components:

CT Droop is required when a generator must to operate in parallel with other generator(s) or the grid. Parallel droop control is a current sensing circuit that use a current transformer (CT). The droop CT output is connected to the AVR sensing supply, which is the voltage feedback signal from the main stator. The droop circuit requires a current signal connected to appropriate terminals of the AVR.
CT droop must be selected in the right way depending the model of generator and AVR and the constituent operating parameters.
