1FL6066-1AC61-2LH1

What type of motor is this?

It is a permanent-magnet synchronous servo motor from the SIMOTICS S-1FL6 family, designed for precise speed and position control in automation axes.

What are the rated speed, rated torque, and rated power?

Rated speed is 2,000 rpm, rated torque (100 K) is 8.36 Nm, and rated power is 1.75 kW.

What peak torque and maximum speed can it reach?

Maximum torque is 25.10 Nm and maximum speed is 3,000 rpm (application and drive configuration dependent).

What are the rated and maximum currents?

Rated current is 5.3 A and maximum current is 15.9 A.

Is this a high-inertia motor and why does that matter?

Yes, it is a High Inertia variant with a moment of inertia of 23.700 kgcm², which is typically selected for axes with higher reflected load inertia or where smoother speed stability is beneficial.

What feedback device (encoder) is fitted?

It is equipped with an absolute encoder with 20-bit singleturn resolution plus 12-bit multiturn capability, enabling absolute position information across multiple revolutions.

Does it include a holding brake, and what are the brake details?

Yes. The holding brake provides 12.00 Nm holding torque and is rated at 24 V DC (±10%) with a rated current of 1.50 A; typical opening time is 180 ms and closing time is 60 ms.

Is it suitable for vertical axes or suspended loads?

It includes a holding brake that can help hold position when the axis is at standstill, which is commonly used on vertical axes; the axis design should still account for load, gearing, and any external forces.

What is the degree of protection and what environment is it intended for?

The motor is rated IP65, intended to resist dust ingress and water jets; actual suitability depends on installation details such as cable glands, connectors, and machine design.

What mounting arrangement does it use?

It is supplied in IM B5 (Code I) flange-mount form, with additional permissible orientations noted as IM V1 and IM V3 in the motor data.

What shaft style does it have?

It has a plain (smooth) shaft end, intended for coupling or pulley arrangements that rely on appropriate clamping or hub design.

What are the permitted ambient operating conditions?

Ambient operating temperature is 0 to 40 °C, and maximum relative humidity is 90% (non-condensing, with the non-condensation condition referenced at 30 °C).

How is the motor cooled?

Cooling is natural (self-cooling), meaning it relies on its own thermal design and surrounding airflow rather than a dedicated fan.

What is the connection style for the power/feedback interface?

It uses an angular connector with a rotatable outlet direction, which can help when cable routing space is limited inside the machine.

What compliance markings are stated for this motor?

The motor data lists CE and EAC compliance.

What is the torque constant and how is it used?

Torque constant is 1.70 Nm/A, which can be used for estimation and sizing calculations relating motor torque to current under the specified conditions.

What is the motor’s net weight and why is it useful to know?

Net weight is 13.70 kg, which is useful for mechanical design, axis balancing, and assessing mounting structure requirements.

How can I confirm the exact configuration received?

Compare the motor rating plate details (speed/torque/current, encoder type, brake rating, and mounting form) against your required specification; for reference, this configuration corresponds to Siemens 1FL6066-1AC61-2LH1.
