The Siemens 1FK2104-4AK00-2MA0 is a SIMOTICS S-1FK2 high dynamic servo motor designed for precise motion control in automated machinery. This permanent-magnet synchronous motor features natural cooling and an IP64 enclosure rating, making it suitable for demanding industrial environments where compact size, responsive performance and accurate positioning are required.

Rated for use with SINAMICS S210 3AC 400 V systems, the motor provides a rated power of 0.60 kW, rated speed of 6,000 rpm and rated torque of 0.95 Nm. It delivers a static torque of 1.27 Nm and a maximum torque of 3.85 Nm, with a maximum speed of 8,000 rpm for high-speed positioning applications.

The integrated AM22DQC absolute encoder provides 22-bit resolution with 12-bit multiturn capability, supporting precise feedback for controlled motion tasks. Mechanical features include an IM B5 mounting design, 80 mm flange, 14 mm plain shaft, M17 connector and OCC connection for S210. With a weight of approximately 2.0 kg and an anthracite housing similar to RAL 7016, the 1FK2104-4AK00-2MA0 offers a robust and compact servo motor option for industrial automation systems.

What type of motor is this component?

It is a SIMOTICS S-1FK2 permanent-magnet synchronous servo motor with natural cooling and an IP64 protection rating. It is designed for dynamic motion applications where precise speed and position control are required.

What is the rated output power?

The rated output power is 0.60 kW when used with a SINAMICS S210, 3AC 400 V drive configuration.

What are the rated speed and maximum speed?

The motor has a rated speed of 6,000 rpm and a maximum speed of 8,000 rpm.

What torque values should be considered for specification?

Key torque values include a static torque of 1.27 Nm, a rated torque of 0.95 Nm and a maximum torque of 3.85 Nm.

What current ratings does this servo motor have?

The static current is 2.4 A, the rated current is 1.9 A and the maximum current is 8.7 A.

What encoder is fitted to this motor?

This motor uses an AM22DQC encoder, specified as a 22-bit absolute encoder with 12-bit multiturn capability.

What drive family is it intended to work with?

The motor data is specified for use with SINAMICS S210, 3AC 400 V systems. Suitability should be checked against the machine design, drive settings and the motor nameplate.

What type of motor connection does it use?

The motor uses an OCC connection for S210 with an M17 connector size.

What are the main mechanical mounting details?

The motor has an IM B5 mounting design, with IM V1 and IM V3 mounting orientations also indicated. It has an 80 mm flange size, 70 mm centring ring, 90 mm hole circle and 6.5 mm screw-on holes.

What are the shaft dimensions?

The shaft has a 14 mm diameter and a 30 mm shaft length. The shaft end is specified as a plain shaft.

How large and heavy is the motor?

The overall length is 98 mm and the weight is approximately 2.0 kg. The shaft height is 40 mm.

What is the rotor moment of inertia?

The rotor moment of inertia is 0.3500 kgcm², which is relevant when assessing acceleration, deceleration and dynamic load behaviour.

What does the IP64 rating mean for this motor?

IP64 indicates protection against dust ingress and protection against water splashes from all directions. The final installation environment should still be assessed to ensure the enclosure rating is suitable.

What colour is the motor housing?

The housing colour is standard anthracite, similar to RAL 7016.

What should be checked when replacing an existing motor with this unit?

When replacing an existing unit with 1FK2104-4AK00-2MA0, check the nameplate, flange and shaft dimensions, encoder type, connector arrangement, drive compatibility, torque requirements, speed range and mounting orientation before installation.
