-
Rated Speed: Up to 3000 rpm (nameplate variant dependent)
-
Feedback: Usually resolver or incremental encoder, “SSS” indicates special shaft/seal/connector configuration
-
Insulation: Class F (155 °C)
-
Mounting: Flange with metric or NEMA pilot
-
-
Functional Features: Low cogging magnet design, rare-earth Neodymium magnets, thermistor or PT100 optional, IP65 housing with shaft seal.
-
Application Scenarios: Spindle auxiliaries, rotary indexing tables, labelers, textile feeders.
-
Installation Requirements: Rigid flange mounting on machined surface, balanced coupling, separate grounded shield for encoder/resolver cable.
