Additional Information for Synchros and Resolvers Additional Information for Synchros and Resolvers

NATO Supply Class 5990 is a classification within NATO Supply Group 59, which is dedicated to Electrical and Electronic Equipment Components.

Specifically, NATO Supply Class 5990 focuses on Synchros and Resolvers. Synchros and resolvers are types of electrical devices used for measuring and transmitting angular position or velocity information. They are commonly used in various applications, including navigation systems, control systems, and robotics.

Synchros are electromechanical devices that convert an electrical signal into a mechanical motion or vice versa. They are often used for precise positioning or tracking of rotating machinery. Resolvers, on the other hand, are similar to synchros but are typically used for measuring angular position or velocity in a more rugged and reliable manner.

In the context of NATO Supply Class 5990, you can expect to find various types of synchros and resolvers, including different sizes, configurations, and specifications. These components are essential for the operation of electrical and electronic systems that require accurate measurement and control of angular position or velocity.

When procuring or working with synchros and resolvers in NATO Supply Class 5990, it is important to ensure compatibility with the specific application requirements and system specifications. This may involve considering factors such as voltage ratings, frequency response, accuracy, and environmental conditions.

Overall, NATO Supply Class 5990 plays a crucial role in providing standardized classification and procurement guidelines for synchros and resolvers within the broader field of electrical and electronic equipment components.

Supply Items Included in Federal Supply Class 5990 Supply Items Included in Federal Supply Class 5990

Adapter,Synchro 126 Items
Cover,Synchro Receiver Mount 42 Items
What is a Differential Receiver Synchro? 109 Items
A Differential Receiver Synchro (SYNCHRO,DIFFERENTIAL RECEIVER) is a synchro, the rotor of which is free to turn, which will assume a position in accordance with the sum or difference of the electrical angular information received from two transmitter synchros. Does not include variable resistors, goniometers, variable transformers, or items with dials.
What is a Differential Transmitter Synchro? 529 Items
A Differential Transmitter Synchro (SYNCHRO,DIFFERENTIAL TRANSMITTER) is a synchro, the rotor of which is mechanically positioned for modifying electrical angular information, received from a transmitter synchro and transmitting to receiver synchro or control transformer synchro electrical information corresponding to the sum or difference of the electrical input angle and its rotor position angle. Does not include variable resistors, goniometers, variable transformers, or items with dials.
What is a Receiver Synchro? 661 Items
A Receiver Synchro (SYNCHRO,RECEIVER) is a synchro consisting of a stator and rotor inductively coupled. The rotor is free to turn in accordance with the electrical input from a transmitter synchro or a differential synchro. Does not include variable resistors, goniometers, variable transformers, or items with dials.
What is a Transmitter Synchro? 1722 Items
A Transmitter Synchro (SYNCHRO,TRANSMITTER) is a synchro consisting of a stator and rotor inductively coupled. The electrical output of the stator into a receiver synchro, a control transformer or differential synchro is dependent upon the position of its rotor. Does not include variable resistors, goniometers, variable transformers, or items with dials.
What is a Control Transformer Synchro? 1126 Items
A Control Transformer Synchro (SYNCHRO,CONTROL TRANSFORMER) is a synchro consisting of a stator and rotor inductively coupled. The electrical output of the rotor is dependent upon both the position of the rotor and the electrical input to the stator from a transmitter synchro or a differential synchro. Does not include variable resistors, goniometers, or variable transformers.
What is an Electrical Resolver? 1598 Items
An Electrical Resolver (RESOLVER,ELECTRICAL) is an item consisting of a rotor and a stator inductively coupled. It usually has two rotor windings displaced from each other by 90 degrees and two stator windings similarly displaced. The output voltage(s) is a trigonometric function of the input voltage(s) and the angular displacement of the rotor with respect to the stator. See also SYNCHRO (as modified) and GONIOMETER, ELECTRICAL. Excludes TRANSOLVER, ELECTRICAL and potentiometer sine/cosine electrical resolvers.
What is a Receiver-Transmitter Synchro? 133 Items
A Receiver-Transmitter Synchro (SYNCHRO,RECEIVER-TRANSMITTER) is a synchro having a dual purpose. It may be used in applications requiring either a receiver or transmitter. For synchros having a single purpose, see SYNCHRO, RECEIVER and SYNCHRO, TRANSMITTER.
What is a Linear Electrical Resolver? 159 Items
A Linear Electrical Resolver (RESOLVER,ELECTRICAL,LINEAR) is an item consisting of a stator and rotor inductively coupled which provides accurate linear indication of shaft rotation about a reference position in the form of a polarized voltage whose magnitude is proportional to angular displacement and phase relationship indicates direction of shaft rotation. Its windings and slots are not uniformly distributed, but instead are deliberately modified to produce a linear output which is usually limited to less than plus or minus 90 degrees of effective electrical travel. Normally it has only one energization winding and one output winding. See also RESOLVER, ELECTRICAL.
What is an Electrical Transolver? 49 Items
An Electrical Transolver (TRANSOLVER,ELECTRICAL) is an item consisting of a rotor and a stator inductively coupled. It has wye connected and quadrature windings, either of which can be stator or the rotor and serve as the Primary for input voltages. The output voltages are trigonometric functions of the input voltages and the angular displacement of the rotor with respect to the stator. See also SYNCHRO (as modified). Excludes RESOLVER, ELECTRICAL and potentiometer sine/cosine electrical resolvers.
What is a Shaft Angle To Digital Encoder? 750 Items
A Shaft Angle To Digital Encoder (ENCODER,SHAFT ANGLE TO DIGITAL) is an electromechanical device, the electrical output of which represents in digital form a mathematical function of the angular position of the input shaft. See also CONVERTER, ANALOGUE TO DIGITAL.
What is a Synchro Rotor? 86 Items
A Synchro Rotor (ROTOR,SYNCHRO) is a rotor which is part of a synchro.
What is a Synchro Stator? 108 Items
A Synchro Stator (STATOR,SYNCHRO) is a stator which is a part of a synchro.
What is a Synchro Assembly? 328 Items
A Synchro Assembly is two or more synchros on a common mounting or mounted on each other. Do not use this name for single synchros mounted with common synchro accessories such as pulleys, gear reduction units, starting mechanisms.
