Hollow-Shaft Motor-Feedback Systems

The SRM-64 servomotor-feedback systems with Hiperface interface provide absolute feedback positioning with 32,768 steps/rev over 4,096 revolutions.

In addition, they provide 1,024 sine-cosine cycles/turn to produce up to 4 million counts/turn after a/d conversion. The IP65-rated units operate over a temperature range from -20 to 110°C with shock resistance up to 100 g/msec and vibration resistance up to 2,000 g/Hz. The hollow-shaft bore accepts shafts up to 14-mm diameter.
