Hollow Shaft Resolvers

Resolvers for Smarter Motors

The use of sensors for determining angles increases with progressive automation. The hollow shaft resolver has long won its own steady position on the market and can nowadays be found in many modern, high-precision control systems. Learn more about how TE's resolvers enable more efficiency in your motor applications.

Reliability and high precision. Due to its design, the hollow shaft resolver boasts of a service live above average. Reliability as well as high precision and low space requirements supplement its favorable characteristics. It remains fully operable even under extreme environmental conditions. Essentially, the resolver mechanically consists of a stationary stator and a movable rotor. Electrically it consists of of a transformer for supplying the rotor with power and a second transformer for determining angles. As one of the largest sensor and connectivity companies in the world, TE Connectivity offers a resolver portfolio, which can be connected with a wide range of servo motor connectors and further sensor application - specifically for your requirements.
