SIMOTICS S Synchronous servo motor 1FK7 Compact 0.85Nm, 100K, 6000rpm 0.38kW, Naturally cooled Power/signal connectors

## Product Overview The SIMOTICS S 1FK7 synchronous servo motor exemplifies precision engineering for compact servo applications, delivering 0.85 Nm torque at 6000 rpm, powered by a 0.38 kW naturally cooled unit. ### Performance Specifications - **Torque & Speed:** Rated nominal torque of 0.85 Nm sustained at a maximum rotational velocity of 6000 rpm, optimized for high-dynamic servo control loops. - **Power Rating:** 0.38 kW power output under natural convection cooling; absence of forced cooling limits continuous overload capacity. - **Electromechanical Interface:** Incorporated power and signal connectors enable integrated control and feedback pathways essential for closed-loop servo systems. ### Structural and Auxiliary Components - **Enclosure and Frame:** Aluminum-metallic construction available in multiple modular configurations (1- to 5-fold), dimensions ranging from 80x80 mm to 364x80 mm, providing structural rigidity and EMI shielding. - **Control Interface Elements:** Inclusion of DELTA switches, pushbutton switches, and LED lamp inserts designed for operational state indication and control function integration within automation systems. - **Protective Devices:** Equipped with NH3 630A fuses to provide overcurrent protection compliant with industrial standards. ### Limitations and Operational Parameters - **Electrical Parameters:** Rated voltage, current, power factor, and frequency unspecified; necessitates system-level specification for tailored application compatibility. - **Thermal and Environmental:** Lacks integrated anti-condensation heaters and temperature sensors (PTC/RTD), limiting deployment in high humidity or wide temperature fluctuation environments. - **Control Capability Restrictions:** Not designed for frequency variation control; absence of overload capacity constrains operation under transient torque conditions. This synchronous servo motor is engineered for precision motion tasks where compact footprint and robustness are critical, yet requires complementary system components to realize full operational envelope.
