What is the rotary transformers? How to winding the stator? How is the rotationally variable structure?

Many friends do not know what rotary transformers are? In fact, rotary transformers are a kind of electromagnetic sensors, also called synchronous decomposers, mainly used to measure the angle, measuring the angular displacement and angular velocity of rotating objects, mainly composed of rotor and stator. how to winding the stator? variable structure?

Stator winding.

Common magnetoresistive rotary transformers, mostly in the form of internal stator, need to wind multiple turns and winding feet, available internal winding machine to solve the winding problem, in order to improve production efficiency, often use four-station or six-station high-speed winding machine.

Rotating variable structure form.

Wiring method is different, the winding structure is different, can get and the angle of rotation into a different function of the output voltage.

Generally speaking, there are two types of rotary transformers, including two-pole winding and four-pole winding, two-pole winding stator-rotor pair of poles each, and four-pole winding two pairs of poles each.

Regardless of the structural form of rotary transformers, the main use of high-precision detection system, of course, in addition to these two common structural forms, there are also multi-pole rotary transformers, commonly used in high-precision absolute detection system.

What is the rotary transformers? How to winding the stator? How is the rotationally variable structure? The above is a simple explanation, I hope it will help you!
