The standard Rotasyn resolver may be the ideal choice for classic machines or electric motors. The "servo slot" allows for easy alignment of the angle encoder with the pole direction of the permanent magnet motor during assembly. Modern servo amplifiers or resolver converters are capable of electronically aligning the resolver with the permanent magnet motor.
In such cases, a Rotasyn resolver with a fixed flange might be the optimal solution, as it can be installed more quickly, requires no mechanical adjustment, and is easy to replace.
Rotasyn standard resolvers are available in two configurations:
The **Admotec-RO Series Rotasyn Variable Reluctance Frameless Resolvers** deliver high performance in measurement and feedback applications where traditional resolvers fail. They are ideally suited for aerospace, downhole, nuclear energy, and similar demanding fields.
These solid-rotor resolvers provide OEMs with reliable solutions for any quantity, from prototype units to high-volume production.
Rotasyn resolvers, with fewer parts, a robust solid rotor, and no windings, are significantly simpler than traditional brushless resolvers. Because the solid rotor has no coils, the stator has only half the number of windings found in conventional resolvers.
The reliability of these brushless resolvers is significantly improved. The solid rotor allows it to operate immersed in hydraulic oil or other fluids.
Rotasyn resolvers are mechanically and electrically compatible with traditional brushless resolvers and can replace them as original equipment or in existing applications. If our standard products do not meet your needs, a custom version can be quickly designed for your application.
**Product Features**
* **Structural Design:** Utilizes a solid rotor with no windings, reducing the potential for wear and failure. Compared to traditional brushless resolvers, they have fewer parts, a simpler structure, and significantly improved reliability.
* **Performance Advantages:** High precision with accuracy better than �18 arc minutes and repeatability better than �1 arc minute. Can withstand pressures up to 1600 bar and speeds up to 10,000 RPM. Wide operating temperature range from -196癈 to approximately +220癈.
* **Environmental Adaptability:** Capable of operating with the rotor immersed in liquids such as hydraulic oil. Suitable for harsh environments like aerospace, downhole, and nuclear energy. Equipped with sealed cables and connectors and splined couplings. Strong anti-interference capability and ability to withstand vibration and shock.
* **Compatibility:** Mechanically and electrically compatible with traditional brushless resolvers, allowing for easy replacement of original equipment or existing resolvers.
**Main Models**
Include RO2010, RO2613, RO3620, RO5032, RO6040, RO7557, RO8565, RO10080, etc. Taking the RO2010 as an example, it is a frameless Size 8 solid rotor resolver with a stator outer diameter of 20 mm and an airgap diameter of 10 mm, suitable for shafts up to 4 mm in diameter.
**Application Fields**
Widely used in:
* **Aerospace:** e.g., flight control systems in aircraft, position feedback for hydraulic actuators.
* **Energy Sector:** e.g., angle measurement in downhole equipment for oil and gas extraction.
* **Automotive Industry:** e.g., electric power steering systems, engine control systems.
* **Mechanical Engineering:** e.g., axis angle measurement and position control in machine tools and robots.
* **Medical Technology:** e.g., angle measurement and positioning of rotating components in medical imaging equipment.
The **Admotec-DG Series Rotasyn Dual-Gap Resolvers** provide high performance in measurement and feedback applications where traditional resolvers fail. These solid-rotor, dual-rotor resolvers are ideally suited for aerospace, downhole, nuclear energy, and other harsh applications, offering OEMs reliable solutions for any quantity, from prototype units to high-volume production.
