Product Description:
The 2AD160B-B35OA1-BS03-A2N1 is a 30-kW servo motor from the 2AD series, engineered by Indramat for industrial automation systems. It employs an axial blower with an air configuration of B to A side through the motor's body. The power that the blower uses is 176 W and it pumps 659 CFM of air per hour on average for maintaining ambient temperature.
The 2AD160B-B35OA1-BS03-A2N1 servo motor is presented with a frictionless without seal shaft, that has a plain design to reduce as much vibration as possible. The rotational inertia is 1740 kgxcm^2 and the motor delivers a steady torque of value 19100 Ncm. The 2AD motor's balance type R permits only 1.8 mm/sec vibrations at 1500 RPM. This motor features a relative indirect position detection encoder system that has 0.0090 degrees of absolute accuracy without the need for an external incremental system. The 2AD servo motor uses 72 A of continuous current to rotate at normal speed of 1500 RPM while its maximum attainable angular speed goes up to 6000 RPM with its equipped standard ball bearings. It lacks a holding brake in the pre-factory assembly but an off-board 24 V brake is supported if the need arises.
The 2AD160B-B35OA1-BS03-A2N1 AC servo motor requires a 3-phase 305 V source to operate and its power terminations occurs to A sided junction box above the enclosure. It weighs about 205 kg and takes 1 hour to cool down on its own by 50% from the present thermal value. The 2AD servo motor comes with a one-sided shaft that does not support any attachments of its side B. At 1 meter distance the noise level produced by this motor is measured 7.5 (B), with ~3(B) tolerance.
Frequently Asked Questions about 2AD160B-B35OA1-BS03-A2N1:
Q: Why is an indirect position detection encoder used in the 2AD160B-B35OA1-BS03-A2N1?
A: The indirect encoder allows precise angular tracking (0.0090 degrees accuracy) without relying on external incremental systems, simplifying feedback integration.
Q: What is the benefit of using a plain shaft design in this motor?
A: The plain shaft reduces torsional vibration and mechanical resonance, improving motor longevity and positional stability in sensitive applications.
Q: Why does the 2AD160B-B35OA1-BS03-A2N1 lack a pre-installed holding brake?
A: The design targets continuous motion systems, but external 24 V brakes can be added for applications needing static shaft locking.
Q: What is the role of the R-type balancing in this motor?
A: R-type dynamic balance limits vibration to 1.8 mm/sec at 1500 RPM, which helps protect connected components and ensures quieter operation.
Q: What advantage does a 3-phase 305 V source provide for 2AD160B-B35OA1-BS03-A2N1?
A: It enables consistent power delivery, helping maintain performance during continuous duty cycles or peak load operations.
