Resolvers for Motion Control

Resolvers are important components for systems that need accurate position feedback and speed control. They are widely used in sectors where precision and reliability are paramount. Position resolvers provide exact measurements of angular position and rotational speed, making them ideal for motion control in difficult environments.

Our resolvers are commonly employed in various applications, including robotics, automation systems, aerospace, and industrial machinery. 

• Robotics: They ensure that joints and motors move with exact precision. In automation, they play a key role in conveyor systems, CNC machines, and other automated equipment, delivering accurate positional feedback for smooth operation.

• Aerospace industry: In the aerospace industry resolver sensors are used in navigation and control systems, where even the smallest margin of error is unacceptable. They are also found in military systems, providing reliable performance in challenging conditions. 

• Marine Applications: A position resolver is essential in marine applications and the oil and gas industries, where accurate position feedback is critical for machinery and equipment in harsh, high-stakes environments.

• Manufacturing Equipment: In manufacturing, these sensors are vital for providing precise control in machinery like automated assembly lines, ensuring smooth and consistent operation even in high-speed processes.

• Electric Vehicles: Industrial resolvers are used in electric vehicle systems. They provide accurate feedback on motor position and speed, ensuring efficient power delivery and smooth acceleration.

Their versatility makes them ideal for any application requiring robust and reliable position sensors. Their ability to function in extreme conditions makes them indispensable for industries that demand high-performance motion control.

While both technologies provide precise position and speed feedback, they operate in different ways and are suited to different applications. Encoders use optical, magnetic, or capacitive sensing to generate digital signals, offering high-resolution feedback for motion control systems. In contrast, resolver sensors are analogue devices that use electromagnetic principles to determine position, making them highly durable and reliable in harsh environments.

One of the key differences is that encoders typically provide absolute or incremental position data with a higher level of precision, whereas resolver-based systems excel in extreme conditions such as high temperatures, vibrations, and electromagnetic interference. This makes them ideal for demanding industries like aerospace, automotive, and heavy-duty industrial applications.

Choosing between the two depends on the specific requirements of your system. If you need ultra-high accuracy and digital integration, encoders are often the best choice. However, for rugged reliability in challenging conditions, a resolver-based solution may be more suitable.
