1FL6034-2AF21-1LA1

What type of motor is this?

This unit is a SIMOTICS S-1FL6 permanent-magnet synchronous servo motor designed for precise, dynamic motion tasks. It is a low-inertia motor, which makes it well suited to applications where fast acceleration and responsive positioning are important.

What are the rated power, speed and torque?

The motor is rated at 0.40 kW, with a rated speed of 3,000 rpm and a rated torque of 1.27 Nm. These values make it a practical choice for compact servo axes requiring consistent motion performance.

What is the maximum speed and peak torque?

The maximum speed is 5,000 rpm and the maximum torque is 3.82 Nm. This gives the motor additional performance headroom above its nominal operating point when the application demands short-term peak output.

Does this version include a brake?

No. This version is a non-braked motor. If a holding brake is required for the application, a different variant should be selected.

What kind of encoder is fitted?

This motor is equipped with an absolute encoder with 20-bit single-turn resolution plus 12-bit multi-turn capability. In Siemens designation, 1FL6034-2AF21-1LA1 is the absolute encoder version.

What supply arrangement is it specified for?

It is specified as a 230 V 3 AC motor. In practice, this motor is typically used as part of a matched servo system rather than as a stand-alone mains-connected motor.

What is the motor frame size?

The motor has a shaft height of 30 mm and a net weight of 1.50 kg. This compact format can be helpful where panel and machine space are limited.

What shaft design does it use?

The motor uses a feather key shaft end. This is useful where a keyed mechanical connection is preferred for transmitting torque to the driven component.

What mounting arrangements are supported?

The standard mounting arrangement is IM B5, with IM V1 and IM V3 also stated in the motor data. This gives flexibility for different machine layouts and installation orientations.

What is the ingress protection rating?

The motor is rated IP65 according to the stated design information. This level of protection is commonly selected where resistance to dust ingress and low-pressure water exposure is needed at the motor body.

How is the motor cooled?

This model uses natural cooling. That means it does not rely on a separate forced cooling arrangement for normal operation within its specified limits.

What are the permitted ambient operating conditions?

The stated ambient operating temperature is 0 to 40°C. Maximum relative humidity is 90% RH, with no condensation at 30°C.

What are the rated and maximum current values?

The rated current is 2.6 A and the maximum current is 7.8 A. These values are important when pairing the motor with a suitable servo drive and sizing the overall motion system correctly.

Is this a low-inertia motor?

Yes. It is specified as a low-inertia motor with a moment of inertia of 0.351 kgcm². This characteristic is often preferred for responsive motion control and rapid speed changes.

What standards compliance is stated for this motor?

The motor data states compliance with CE and EAC. These markings indicate conformity with the relevant stated requirements for those markets.

What kind of applications is this motor typically suited to?

This servo motor is generally suited to compact automation duties that need accurate speed and position control, such as indexing systems, conveyors, light handling axes, packaging equipment and other precision motion tasks within its performance range.

How does the motor connect electrically?

The connection type is listed as cable outlet. This is useful for installations where pre-defined cable routing and a compact motor connection arrangement are preferred.
