The Siemens 1FT5104-0AC71-1 AC servo motor is engineered for high performance. Its torque constant is measured at 1.09 Nm/A, while the voltage constant is rated at 123 V per 1000 RPM. This motor's winding resistance per phase is 0.095 ohms, and it showcases a phase inductance of 1.7 mH, effectively managing its electrical characteristics.

The motor functions at a DC link voltage rating of 600 volts, providing efficient power handling. Rated to deliver 45 Nm of torque, this unit is capable of maintaining continuous operation at speeds of 2000 RPM. With a rated current of 45 amps, it effectively supports various demanding applications.

Cooling is achieved through a non-ventilated design, which contributes to the motor's operability in specific configurations. This servo motor adheres to protection class IP 64, which enhances its utility in environments subject to dust and moisture.

For installation versatility, the mounting arrangement supports IM B5 configurations (including IM V1 and IM V3). Feedback is facilitated through an incremental encoder and a tachogenerator, enhancing its responsive controls. Weighing in at 47 kg with the brake, the motor is robust yet manageable for various industrial setups.
