Product Description:

The AM8561-0G21-0000 is a Brushless servo motor manufactured by Beckhoff that is used in systems that require reliable control and accurate torque delivery. Beckhoff delivers the product under recognized international standards to meet automation demands.

The AM8561-0G21-0000 brushless servo motor has excellent position holding capability with a holding torque of 20 Nm at 120°C. Acceleration profiles may be fine-tuned due to the rotor's 50.60 kgcm² moment of inertia when the brake is on and 48.20 kgcm² when it is not. To reduce the likelihood of accidental motion while at rest, the motor has a static friction torque of 0.045 Nm. It can be securely mounted on predetermined frames due to its weight of 14.80 kg with brakes and 13.20 kg without brakes. The motor's consistent braking action is guaranteed by its usage of a 24 VDC supply voltage with a tolerance of ±6% to -10%. In constant use, the brake draws 0.72 A of current and consumes 24 W of electrical power. Its 10-pole configuration determines its magnetic properties for controlling torque and speed. The motor is compatible with aligned mechanical couplings thanks to its flange fit class J6 and tolerance class N, which meet the requirements of IEC standard / DIN 42955.

The AM8561-0G21-0000 servo motor provides protection class IP65 for both the standard housing and the shaft bushing with sealing ring that ensures effective sealing against particles. The shaft feed-through version comes with IP54 that provides additional configuration options. The paint finish is acrylic powder-coated, which enhances surface durability. The color is dark gray with RAL 7016 standard that supports identification in panel assemblies. The motor performance remains consistent due to its defined thermal parameters and precise delay characteristics.

Frequently Asked Questions about AM8561-0G21-0000:

Q: Why does AM8561-0G21-0000 have IP65 protection class?

A: It protects the motor against dust and low-pressure water jets. Ensures durability in enclosed automation assemblies and control cabinets.

Q: How does AM8561-0G21-0000 manage heat buildup?

A: The thermal time constant of 35 minutes delays temperature rise. It allows stable operation during prolonged motor usage and braking cycles.

Q: Why does AM8561-0G21-0000 use a 24 VDC brake?

A: A 24 VDC brake ensures standard voltage compatibility. It supports reliable engagement and release under typical control voltages.

Q: Do AM8561-0G21-0000 specifications meet DIN standards?

A: Yes, it meets IEC and DIN 42955 standards. This ensures mechanical tolerance and fit compatibility across industry-standard interfaces.

Q: How does AM8561-0G21-0000 improve positioning accuracy?

A: It provides 0.045 Nm static friction torque. This prevents drift and maintains shaft position during system inactivity or standby conditions.
