| Product Description | Siemens SIMOTICS S-1FK7 compact permanent-magnet servo motor designed for precise speed, torque, and position control in industrial motion applications. |
What type of motor is this unit?
It is a Siemens SIMOTICS S-1FK7 Compact permanent-magnet synchronous servo motor designed for precise motion, positioning, and speed-control applications.
What are the rated speed and torque?
The motor has a rated speed of 6,000 rpm and a rated torque of 0.6 Nm at the 100 K operating condition.
What are the static torque ratings?
The static torque is 0.70 Nm at 60 K and 0.85 Nm at 100 K. The corresponding stall currents are 1.50 A and 1.80 A.
What are the maximum operating limits?
The limiting values are 10,000 rpm maximum permissible speed, 3.4 Nm maximum torque, and 8.0 A maximum current. Application-specific load conditions must also be considered.
What is the optimum operating point?
The documented optimum operating point is 6,000 rpm with an optimum power of 0.4 kW.
What feedback system is fitted?
The motor uses an IC22DQ incremental encoder with 22-bit resolution, equivalent to 4,194,304 positions. It also has an encoder-internal value of 2,048 S/R and an 11-bit commutation position.
Does the motor include a holding brake?
No. Siemens 1FK7022-5AK71-1DG5 is configured without a holding brake.
What type of shaft does the motor have?
The motor is supplied with a plain shaft rather than a keyed shaft.
What is the enclosure protection rating?
The motor has an IP65 degree of protection, while the drive-end flange is rated IP67.
How is the motor cooled?
It uses natural cooling and does not require a separate forced-air cooling arrangement under its specified operating conditions.
Which mounting positions are specified?
The motor has an IM B5 flange-mounted design and is also specified for IM V1 and IM V3 vertical mounting orientations.
What temperature monitoring device is included?
A Pt1000 temperature sensor is integrated for monitoring the motor temperature.
What are the recommended inverter current ratings?
The recommended motor module ratings are 3 A rated inverter current and 6 A maximum inverter current.
What is the motor's efficiency?
The documented efficiency is 86 percent.
What are the motor's size and weight?
The motor has a shaft height of 28 mm and a net weight of approximately 1.8 kg.
What electrical connection arrangement is provided?
Separate signal and power connectors are provided, and the connectors can be rotated to simplify cable orientation during installation.
What is the housing color?
The standard housing finish is anthracite gray, RAL 7016.
What applications is this servo motor commonly suited to?
Its compact construction, high-resolution encoder, and fast dynamic response make it suitable for positioning axes, packaging machinery, machine tools, material handling equipment, assembly systems, and other automated motion applications.
What should be checked when replacing an existing motor?
Confirm the complete ordering code, mounting orientation, flange and shaft dimensions, encoder type, connector arrangement, brake configuration, speed and torque requirements, current ratings, and compatibility with the installed drive system.
