TE Connectivity (TE) offers a comprehensive portfolio of hollow-shaft resolvers for “smart” servo motors. The use of sensors for determining angles is increasing with progressive automation. TE’s hollow shaft resolvers can nowadays be found in many modern, high-precision control systems such as servo motor feedback systems and positioning.
The resolvers are accurate to within plus or minus 8 arc minutes, depending on product variants. They have the ability to remain fully operational even under extreme environmental conditions, have low sensitivity to electromagnetic interference and long lifetimes due to a robust mechanical structure and automated coil incorporation. TE’s resolvers also offer resistance to humidity, many lubricants, shock and vibration.
TE resolvers incorporate one transformer for powering the rotor and a second transformer for determining angles. They have a maximum rotational speed of 20,000 rpm and provide absolute angular information throughout 360 degrees, depending on the version they operate from one up to four speeds. Operating temperature range is minus 55 degrees Celsius to 150 degrees Celsius. The resolvers are available in size 15 and 21 (diameter).
To complement its resolvers for servo motors, TE also offers magnet wire automation and a wide variety of reliable circular and rectangular connectors for any size of motor and for numerous applications. TE resolvers can be connected directly to the company’s Intercontec connectors.
