Frameless /
Built-in Resolver

This is a brushless frameless / built-in type resolver and integrated into servo motor, direct drive and others. This type of resolver has been used for motor feedback sensor for long years. Stator and rotor winding are made by automatic winding machine for stable quality and large number of production. Number of pole pair is normally from 1X (1 number of pole pair) to 5X. Standard size is from 08, 10, 15 and 21. TAMAGAWA SEIKI has experience of smaller size 06 and larger size 34 too.
