Swiss ADMOTEC Rotary Transformer RO7557
Swiss ADMOTEC rotary transformers have become the preferred choice for applications such as aerospace, energy exploration, and automotive industry due to their reliability and precise measurement capabilities.
Admotec's position detector technology (rotary transformer technology) produces fewer rotary transformer parts, with sturdy rotors, no slots, windings, and no need for rotary transformers. Unlike other variable reluctance rotary transformers, Rotasyn uses a constant air gap, making it less sensitive to eccentricity and stray magnetic fields. It interfaces directly with standard R/D converters.
Admotec RO series rotary transformers are used in measurement and feedback applications. These robust rotor parsers are suitable for aerospace, deep well, nuclear, and other applications, providing solutions for equipment manufacturers from prototype units to large-scale production. Rotasyn's components and winding free rotor make it simpler than traditional brushless parsers. Due to the lack of coils in the sturdy rotor, the stator only has half the winding count of traditional brushless parsers,. And the sturdy rotor allows for operation when the rotor is submerged in hydraulic oil or other liquids.
RO series: As a frameless hollow shaft model, the RO series adopts a variable reluctance frameless design, which is suitable for integration into space limited applications. This series offers two temperature versions: the ROxxxx-M model has a working temperature of -55 to+155 ° C, and the ROxxxx-K model has a working temperature of -196 to+220 ° C.
DG series: As a bearing encoder for shaft assemblies, the DG series provides packaging solutions. For example, the working temperature of DG2-3620-M is -40 to+150 ° C, while the working temperature of DG2-3620-K is -60 to+230 ° C ⟮ 5 ⟯ 8 ⟯, suitable for applications that require higher temperature tolerance.
When choosing an ADMOTEC rotary transformer, the following key factors should be considered:
1. Temperature range: Select the appropriate model based on the application environment temperature. For example, the ROxxxx-K series is suitable for low or high temperature environments (-196 ° C to+220 ° C), while the ROxxxx-M series is suitable for conventional industrial environments (-55 ° C to+155 ° C) ⟮ 7 ⟯.
2. Pressure rating: For high-pressure environments (such as hydraulic systems), high pressure resistant models should be selected, and some products can withstand pressures up to 1600 bar.
3. Medium compatibility: If the rotor comes into contact with liquids (such as hydraulic oil), products designed with solid rotors, such as RO or DG series, should be selected.
4. Installation method: Choose the frameless model (RO series) or the bearing seat equipped model (DG series) according to space limitations and installation conditions.
5. Accuracy requirements: Select the appropriate series according to the application accuracy requirements. The accuracy of ADMOTEC rotary transformers is usually better than ± 18 arc minutes, and some models have an angle error of ± 60 arc minutes.
