Product Overview
The Siemens 1FK7060-2AF71-1CG0 belongs to the SIMOTICS S-1FK7 compact synchronous motor family used in industrial servo-drive systems. It converts controlled electrical power into rotary motion for machine axes that require regulated speed, torque and repeatable movement. Its motor ratings make it suitable for applications requiring more torque than smaller 1FK7 frame variants.
The motor’s rated speed is 3,000 rpm, with a rated torque of 4.7 Nm at a 100 K temperature rise. Its naturally cooled construction and IM B5 flange mounting support integration into compatible machine assemblies without requiring an integrated forced-ventilation unit. The motor can be used in feed mechanisms, packaging equipment, automated assembly machinery and other servo-controlled systems when its performance matches the axis requirements.
When selecting a replacement or configuring a new installation, the complete order number matters. The drive must match the motor’s electrical ratings and the specified encoder, shaft and connection configuration. The mechanical coupling, duty cycle and load inertia also need to be considered to achieve the required motion response.

Working Principle
The 1FK7060-2AF71-1CG0 uses permanent magnets in the rotor and electrically energized stator windings to generate rotary torque. A compatible servo drive supplies controlled three-phase current to the motor, regulating torque and speed in response to commands from the machine controller.
During a positioning cycle, the controller sends a motion command to the drive. The drive regulates motor output according to the configured motor data and feedback arrangement, allowing the axis to accelerate, maintain a commanded speed and decelerate as required. The selected feedback configuration must correspond to the exact motor order number and supported drive interface.
The motor’s rated and maximum operating values serve different purposes. Rated torque and speed are relevant to continuous application sizing, while maximum torque and speed limits apply under their specified operating conditions. The load inertia, acceleration profile, cycle frequency and cooling conditions should be evaluated together rather than using maximum torque as a continuous operating target.

Technical FAQs
What are the rated torque and speed of the 1FK7060-2AF71-1CG0?
The motor has a rated torque of 4.7 Nm at a 100 K temperature rise and a rated speed of 3,000 rpm. Application sizing should also account for load inertia, acceleration, duty cycle and the drive’s operating limits.
How should the maximum mechanical speed be interpreted when configuring the drive?
The maximum mechanical speed is specified as 7,200 rpm, while the maximum inverter speed is 6,700 rpm. The actual operating limit must respect the applicable motor and drive restrictions; the lower relevant limit should be used for the configured system.
Can this motor be substituted directly for another 1FK7060 motor?
Not based on the shared frame designation alone. The full order numbers must be compared for feedback interface, shaft configuration, holding brake, connectors and protection requirements before a replacement is selected.
What factors should be evaluated if the motor overheats during repetitive positioning?
Check the actual RMS torque, acceleration and deceleration profile, cycle frequency, load inertia, drive current settings and surrounding cooling conditions. Operation near peak torque for extended periods can create thermal loading that differs substantially from the rated operating point.
