1FK7062-2AF71-1CB0

What type of motor is this?

It is a permanent-magnet synchronous servo motor from the SIMOTICS S-1FK7 family, intended for precise speed and position control when used with a suitable servo drive.

What is the nominal power and optimum operating point?

The optimum operating point is 1.9 kW at 3000 rpm with an optimum torque of 22.10 Nm (as listed in the engineering data for Siemens 1FK7062-2AF71-1CB0).

What torque can it produce?

In addition to the 22.10 Nm optimum torque, the maximum torque is specified as 26.0 Nm. This helps with short-duration acceleration and load peaks (subject to drive and application limits).

What are the maximum permissible speeds?

Two limits are provided: 7200 rpm maximum permissible mechanical speed, and 5600 rpm maximum permissible speed with the inverter.

What are the key current figures to consider when selecting a drive?

The data lists 19.2 A maximum current. It also lists inverter-side values including 15 A and 5 A (shown alongside “maximum inverter current” and “rated inverter current” in the ordering data). Always size the drive to meet both continuous and peak demands for your duty cycle.

Does it include a holding brake?

Yes. It is supplied with a permanent-magnet holding brake with a holding torque of 13.0 Nm.

What voltage and current are required for the holding brake?

The brake power supply voltage is DC 24 V ± 10%, with a coil current of 0.8 A. The listed opening time is 50 ms and the closing time is 100 ms.

What feedback device is fitted for motion control?

It uses an AM24DQI absolute encoder: 24-bit single-turn (resolution 16,777,216, encoder-internal 2048 S/R) plus 12-bit multi-turn with a traversing range of 4096 revolutions.

What environmental protection rating does it have?

The motor has an IP64 degree of protection, suitable for environments where protection against dust ingress and water spray is required.

What mounting arrangement is used?

The mechanical design is listed as IM B5 (also shown with IM V1 / IM V3 options in the data), which is a flange-mounted configuration commonly used in servo axes.

How is the motor cooled?

Cooling is specified as natural cooling (self-cooled), meaning it relies on its own design and ambient airflow rather than an external fan unit.

What built-in temperature monitoring is provided?

A Pt1000 temperature sensor is included for temperature monitoring, allowing the drive/system to monitor motor temperature via the appropriate inputs.

What are the inertia and weight figures for axis sizing?

The listed moment of inertia is 12.200 kgcm², and the net motor weight is 10.5 kg. These values are useful when checking acceleration performance and mechanical load matching.

What electrical constants are helpful for engineering checks?

The data lists a torque constant of 1.60 Nm/A, a voltage constant at 20°C of 102.5 V/1000 min⁻¹, winding resistance at 20°C of 1.15 Ω, and rotating field inductance of 14.6 mH.
