BACKGROUND
Three-phase alternators are electrical devices used to generate alternating current (AC) power for various applications. These alternators include a rotor which rotates within a stator to produce electrical power. Three-phase alternators further include three separate windings, which are often evenly spaced around a stator of the alternator, each of the windings producing AC voltage. The windings are typically evenly spaced, forming a balanced system that helps ensure a continuous and smooth power output.
In operation, the alternator's rotor is driven by an external mechanical force, such as a turbine, engine, or crankshaft. As the rotor spins within the stator (stationary part), the changing magnetic field induces an electromotive force (EMF) in the windings. Due to the phasing arrangement of the windings, the voltage generated by each winding reaches its peak at a different point in time, creating a consistent and continuous supply of AC power. This arrangement enhances the overall efficiency and stability of the power generation process.
Three-phase alternators provide a constant power output, resulting in smoother performance for electrical systems compared to single-phase generators. Additionally, due to the balanced arrangement of windings, the mechanical stress on the generator is reduced, promoting longevity and reliability. Moreover, three-phase power transmission is more efficient over long distances, making these generators well suited for applications like power plants, industries, large commercial facilities, or electrical grids.

DETAILED DESCRIPTION
Various embodiments will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views. Reference to various embodiments does not limit the scope of the claims attached hereto. Additionally, any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible embodiments for the appended claims.
The current disclosure is directed to multi-phase alternators. A three-phase twelve-lead alternator is a specific configuration of an alternator that has six stator coils and twelve output leads, with each coil having two associated output leads. In some examples, each of the coils is evenly spaced at 60-degree intervals around the stator. This type of alternator is designed to produce a three-phase AC output with twelve leads that can be connected to different load configurations. In some examples, this type of alternator is designed to produce a single phase AC output with twelve leads that can be connected to different load configurations. Each phase has two separate leads, often labeled with subscripts (e.g., A1, A2, B1, B2, C1, C2), indicating the different ends of the stator coils for each phase. The arrangement of the stator coils and the associated leads allows for flexibility in connecting the alternator to various electrical systems.
Similarly, a six lead three-phase alternator has three stator coils arranged around the stator core, each coil positioned 120 degrees apart from the others.
In some examples, alternators are built with dedicated voltages that are unable to be reconfigured. This can be problematic where different voltages are desired, as it requires the use of a different alternator. In other examples, alternators are built with the ability to be reconfigured to produce different output voltages. However, changing the voltage output of a three-phase alternator may be time consuming and error prone, and often times, must be performed by a highly trained technician. In some examples, changing the voltage of a three-phase alternator requires physically disconnecting and reordering alternator leads in a specific orientation. Such processes may also require the use of specialized equipment, such as terminal blocks and jumper blocks. In other examples, changing the voltage requires the use of a voltage selector switch, which is typically bulky and expensive. Other examples require the use of a voltage link board, which are also bulky and usually require trained technicians to operate. In some cases, errors in performing the above methods can lead to damaged equipment.
In some examples, the concepts provided in the current disclosure allow for a single alternator to be used and readily reconfigured to produce one or more different voltages. In some examples, the concepts provided in the current disclosure provide a low cost, reliable way to change the voltage output of an alternator without requiring a trained technician to do so.

As shown in FIG. 12, when assembled, the tabs 176 of the voltage select cartridge 114 extend into the terminals 144 from the rear side 136 of the base 121. In some examples, the cartridge connection posts 152 of the terminals 144 protrude through the holes 177 in the tabs 176 of the voltage select cartridge 114, thereby helping to secure and align the voltage select cartridge 114 within the terminal block assembly 118.
Likewise, as shown in FIG. 12, when assembled, the lead connectors 124 are also arranged within the terminals 144. In some examples, the lead connectors 124 are arranged within the terminals 144 at the front side 134 of the base 121. In some examples, a portion of the lead connectors 124 surrounds the lead connection posts 150 of the terminals 144.
FIG. 13 is a detail perspective view of a connection terminal 146 and a junction terminal 148 of the base 121 with the lead connectors 124 and the tabs 176 of the voltage select cartridge 114 arranged therein.
In some examples, when the connector assembly 112 is assembled, a 122 connection bar is arranged within each of the connection terminals 146 and the junction terminals 148 of the base 121. In some examples, the connection bars 122 are formed as rectangular sheets. In some examples, the connection bars 122 are electrically conductive.

In some examples, the connection bars 122 are substantially planar. In some examples, when arranged within the connection terminals 146 and the junction terminals 148, the connection bars 122 lie flat along the bottom surface 155 of the connection terminals 146 and the junction terminals 148.
In some examples, in each of the connection terminals 146 and the junction terminals 148, when the cartridge connection posts 152 are extended through the holes in the tabs 176 of the voltage select cartridge 114, connection fasteners 126 are threaded onto the cartridge connection posts 152 over the tabs 176 such that the tabs 176 are secured in place between the connection fasteners 126 and the bottom surface 155 of the terminals 144. In some examples, when secured in place against the connection bars 122 the tabs 176 form an electrical connection with the connection bars 122. In some examples, when the tabs 176 are inserted into the terminals 144 of the base 121, the bus bar system 178 of the voltage select cartridge 114 extends out from the rear side of the base 121 and is substantially parallel with the bottom surface 155 of the terminals 144.
In some examples, the lead connectors 124 are formed as ring terminals. In some examples, the lead connectors 124 include a plurality of input connectors 202 and a plurality of output connectors 204. In some examples, each of the connection terminals 146 includes an input connector 202. In some examples, fewer than all of the connection terminals 146 includes an input connector 202. In some examples, each of the connection terminals 146 includes only one input connector 202. In some examples, when arranged within the connection terminals 146, the lead connection post 150 extends through a hole in the input connectors 202. In some examples, the connection fastener 126 is threaded onto the lead connection post 150. In some examples, the input connector 202 is secured within the connection terminals 146 between the connection bar 122 and the connection fastener 126. In some examples, when secured within the connection terminal 146, the input connector 202 forms an electrical connection with the connection bar 122 and respective tab 176 of the respective connection terminal 146.
In some examples, each of the junction terminals 148 also include an input connector 202. In some examples, fewer than each of the junction terminals 148 includes in input connector 202. In some examples, three of the four junction terminals 148 include an input connector 202. In some examples, the input connectors 202 are electrically connected to leads of the stator 110. In some examples, the input connectors 202 provide an electrical connection between the leads of the stator 110 and other components of the connector assembly 112.
In some examples, the output connectors 204 are connected to output leads, which deliver electrical power to other components of an electrical distribution system, such as, for example, a circuit breaker. In some examples, each of the junction terminals 148 includes an output connector 204. In some examples, one or more of the junction terminals 148 may include both an input connector 202 and an output connector 204. In such examples, the input connector 202 and the output connector 204 are stacked on top of one another within the junction terminals 148. For example, in some examples, the input connector 202 is arranged on top of a connection bar 122 of a junction terminal 148 with the associated lead connection post 150 extending through the hole of the input connector 202. The output connector 204 is arranged over the input connector 202 with the with the associated lead connection post 150 also extending through the hole of the output connector 204. The connection fastener 126 is threaded onto the associated lead connection post 150 over the output connector 204. Thus, the output connector 204 is secured between the connection fastener 126 and the input connector 202 is secured between the output connector 204 and the connection bar 122. In other examples, the placement of the input connector 202 and the output connector 204 is reversed such that the input connector 202 is arranged over the output connector 204. In some examples, when secured within the junction terminal 148, the input connector 202 and the output connector 204 are electrically connected to each other and are also electrically connected to the connection bar 122 and the associated tab 176 of the associated junction terminal 148. In some examples, when arranged in the stacked configuration, a portion of one of the input connector 202 and the output connector 204 is located within the recess 156 of the base 121. In some examples, the connection bar 122 forms an electrical connection with the input connector 202, the output connector 204, and the associated tab 176.
