A rotary transformer is a type of variable frequency transformer that allows electrical signals from rotating components to connect without generating unwanted activity. Its unique design reduces wear and friction, promoting longer equipment life and lower repair costs. It is commonly used in recording equipment and motors that rely on AC power.
A rotary transformer is a type of variable frequency transformer that helps improve the process that allows the electrical signals associated with two components that rotate close to each other to connect without generating any kind of unwanted activity. This process can help reduce wear on the components involved and help the equipment containing the components operate more efficiently.
This rotary transformer function is possible due to the basic design used for this type of electronic device. The configuration involves placing the windings in two halves of a common cup core, with one of the windings designated as the primary winding and the other identified as the secondary winding. When mounted in place, these two halves face each other with respect to rotating or moving components. The result of this design is to allow smooth operation of the rotating parts without suffering some of the more undesirable effects that would occur with a different transformer design.
A rotary transformer, correctly installed, can help reduce the incidence of a number of problems which over time would have a negative impact on the machinery. Thanks to the unique design, the potential for some sort of contact between moving parts is minimized. This in turn helps to reduce both friction during operation and wear of the moving parts and allows the rotational speed of the moving parts to remain within acceptable levels. The end result is a longer life for the equipment, which in turn helps promote production and keep repair and replacement costs relatively low.
One of the more common examples of how a rotary transformer can be used is found in various types of recording equipment, including video cassette players/recorders. The transformer function helps to protect the movement of the heads used to drive the tape during the process, resulting in more efficient results. The rotary transformer is also used in several different types of motors, helping to reduce wear between the torque sensors found in many different types of motors today. Typically, this type of transformer is used in designs that rely on the use of alternating current (AC) power, with other devices being used when the equipment is designed to use direct current (DC) power.
