Used Resolvers (all tested and working)

The LTN Servotechnik RE-21-1-K37 is a high-precision frameless resolver designed for accurate position feedback in servo motors and industrial automation systems. As part of the RE-21 series, it features a compact hollow shaft design (up to 17 mm) for direct motor integration and minimal installation space. Operating with typical excitation of around 7 Vrms and frequencies between 1–10 kHz, it provides reliable sine/cosine output signals for precise angle measurement. Built for harsh environments, it offers excellent resistance to shock, vibration, and temperatures from −55 °C to +155 °C, ensuring long-term stability and performance.
