Product Overview

The Siemens 1FK7063-2AF71-1CH1 SIMOTICS S Synchronous Motor is a permanent-magnet synchronous motor from the SIMOTICS S-1FK7 compact motor family. It is intended for industrial servo applications that require controlled rotation, repeatable positioning, and coordinated movement under a compatible drive system. This configuration combines natural cooling, an absolute multiturn encoder with DRIVE-CLiQ communication, a smooth shaft, and an integrated holding brake.

In a servo-motion system, the motor converts electrical energy into mechanical torque while the drive regulates its response to motion commands. Feedback from the encoder allows the drive to monitor rotor position and coordinate speed and torque control. This arrangement supports applications in which machine movements must follow defined operating sequences rather than run continuously at an uncontrolled speed.

The 1FK7063-2AF71-1CH1 has a rated power of 2.3 kW, a rated speed of 3,000 rpm, and a rated torque of 7.3 Nm under the specified 100 K temperature-rise condition. Its static torque rating at the same condition is 11 Nm. These figures help establish whether the motor can meet an application’s basic operating requirements, but final selection also requires evaluation of acceleration, load inertia, peak torque, duty cycle, and the capabilities of the connected drive.

One of the defining features of this model is its AM24DQI absolute encoder. The encoder provides 24-bit single-turn position information and 12-bit multiturn information through the DRIVE-CLiQ interface. This allows a compatible drive system to obtain detailed rotor-position information for motion control and commissioning. The encoder configuration is particularly relevant when selecting a replacement motor because the feedback interface and supported encoder functions must match the drive architecture.

The integrated holding brake supports applications in which the shaft must remain stationary when the motor is not actively producing torque. The brake uses a permanent-magnet design and has a specified holding torque of 13 Nm. Its electrical control, release sequence, and suitability for a particular load must be assessed against the machine’s requirements. A holding brake should not automatically be treated as a dynamic stopping device or as a complete safety function.

The smooth shaft provides a mechanical interface for suitable couplings and transmission components. This arrangement allows the machine designer to select a coupling based on the connected load, alignment requirements, and torque-transfer method. Proper alignment is important because excessive radial or axial forces can affect bearing life and cause vibration or positioning errors.

Natural cooling dissipates motor heat through the housing and surrounding environment. The installation must therefore provide appropriate thermal conditions for the intended operating duty. Ambient temperature, mounting orientation, surrounding airflow, and repeated high-torque movements can all affect the permissible continuous load.

The motor uses an IM B5 flange mounting arrangement, with IM V1 and IM V3 mounting positions supported as specified for this series. Its IP65 protection rating provides protection against dust ingress and water jets under the conditions defined by the rating. Actual suitability depends on the complete installation, including connectors, cable routing, and the environmental requirements of the machine.

The 1FK7063-2AF71-1CH1 is suitable for integration into compatible Siemens SINAMICS servo-drive systems. Drive selection must account for the motor’s electrical ratings, feedback interface, brake control, speed range, and dynamic load requirements. Correct matching helps ensure that the motor and drive operate as a coordinated motion-control unit.

Typical applications include automated assembly equipment, packaging machinery, material-handling systems, and production machinery requiring controlled rotary movement. In each case, the motor must be evaluated against the actual motion profile and mechanical load rather than selected solely by rated power.

The Siemens 1FK7063-2AF71-1CH1 combines permanent-magnet synchronous motor technology, absolute position feedback, and an integrated holding brake for industrial servo applications. Its performance depends on correct drive configuration, feedback integration, mechanical installation, and commissioning.

Working Principle

The Siemens 1FK7063-2AF71-1CH1 operates as the electromechanical actuator in a closed-loop servo system. The compatible drive supplies controlled current to the motor windings, generating a rotating magnetic field that interacts with the rotor’s permanent magnets. This interaction produces torque and drives the shaft.

Motion Command → SINAMICS Servo Drive → Motor Rotation → DRIVE-CLiQ Feedback → Control Correction

The motion controller generates a position, speed, or torque command according to the machine sequence. The servo drive interprets the command and regulates the electrical current supplied to the motor. Adjusting current allows the drive to control torque and influence the motor’s acceleration, deceleration, and operating speed.

As the rotor moves, the AM24DQI encoder provides absolute position information through DRIVE-CLiQ. Its single-turn data identifies the angular position within one revolution, while the multiturn data represents position across multiple revolutions within the encoder’s specified range. The compatible drive uses this information as part of its motion-control process.

Absolute feedback can simplify position management compared with a system that relies solely on incremental signals. However, the actual startup behavior depends on drive configuration, encoder initialization, and machine reference management. The machine designer must verify the required positioning behavior during commissioning rather than assume that every application can resume operation without additional checks.

The integrated holding brake performs a separate function from electromagnetic torque production. During normal movement, the brake must be released according to the specified control sequence. When the shaft needs to remain stationary, the brake can hold the shaft within its rated conditions. The drive and brake-control arrangement must follow the prescribed release and engagement procedure to avoid unnecessary mechanical stress.

The brake’s holding torque must be evaluated against the actual load, transmission ratio, mechanical efficiency, and any external forces acting on the axis. Applications involving suspended loads or safety-related stopping requirements need an appropriately engineered braking and protection arrangement. The integrated brake alone should not be assumed to provide every required safety function.

The motor’s Pt1000 temperature sensor provides winding-temperature information to compatible monitoring electronics. Correct wiring and parameterization allow the drive system to monitor thermal conditions. This is relevant during extended operation, repeated acceleration cycles, and applications where the load changes significantly over time.

Mechanical torque is transferred from the smooth shaft through a compatible coupling or transmission. Coupling alignment, shaft loading, and load inertia influence the motion response. Poor alignment or excessive mechanical loading can cause vibration, additional bearing stress, and reduced positioning accuracy even when the motor and drive are correctly configured electrically.

Natural cooling removes heat through the motor housing and surrounding environment. The available thermal margin depends on the installation conditions and operating duty. If the application requires frequent high-torque movements or sustained loading, the motor’s thermal limits and the drive’s operating envelope must be checked during engineering.

In normal operation, the controller defines the movement, the drive regulates current, the encoder reports rotor position, and the holding brake provides stationary holding when appropriately engaged. The coordinated operation of these elements supports controlled motion in industrial automation systems.

Role in the Industrial Control Architecture

The 1FK7063-2AF71-1CH1 forms the actuator stage of a servo-motion axis. It receives controlled electrical power from a compatible servo drive and returns absolute encoder information through DRIVE-CLiQ. The integrated holding brake is controlled as part of the overall axis design.

Motion Controller → SINAMICS Servo Drive → 1FK7063-2AF71-1CH1 → Mechanical Load

The controller determines the required movement, while the drive regulates motor operation using the encoder feedback. The mechanical transmission and holding-brake arrangement must be selected according to the actual axis requirements.

Technical FAQs

What information does the AM24DQI encoder provide to the servo drive?

The AM24DQI encoder supplies 24-bit single-turn and 12-bit multiturn position information through DRIVE-CLiQ. A compatible drive can use this feedback for rotor-position monitoring and motion control, subject to the configured drive and machine-reference requirements.

How should the integrated holding brake be coordinated with motor movement?

The brake must be released and engaged according to the specified electrical and mechanical procedure. The control sequence should prevent the brake from being used as a routine dynamic stopping device unless the documented ratings explicitly permit that operation.

What should be checked when integrating this motor into an existing SINAMICS axis?

Verify the drive’s compatibility with the motor ratings, AM24DQI encoder interface, holding-brake circuit, and temperature-sensor connection. The machine’s mechanical coupling and motion profile must also be checked before the replacement or installation is commissioned.

Why is Pt1000 temperature monitoring useful during continuous production?

The sensor supplies winding-temperature information to compatible monitoring electronics. This helps the drive system assess thermal conditions during extended operation and repeated acceleration cycles, provided that the sensor connection and monitoring parameters are correctly configured.
