2AD104D-B35OB1-FS0B-B2N1

Product Description

For AC servo motors, bigger is not always better. Although larger motors generally provide higher loading and driving capabilities, smaller motors are more suitable for rapid-response applications, especially when the least amount of space is desirable. When it comes to producing the most sturdy and compact AC servo motors, Rexroth Bosch’s 2AD motor series is a top contender. Most 2AD motors feature relatively smaller motor frames that have a compact centering diameter. Like other Rexroth’s motor series, 2AD motors may support either flange or foot attachments. Taking the 2AD104D-B35OB1-FS0B-B2N1 as an example, this 2AD motor weighs only about 60 kilograms and supports both foot and flange attachments. 

With its FS-winding designation, the 2AD104D-B35OB1-FS0B-B2N1 nominally runs at a speed of 1800 rev/min. At this speed rating, the machine delivers its nameplate parameters. Based on Rexroth Indramat’s 2AD project planning manual, the nameplate power, torque, and current of the 2AD104D-B35OB1-FS0B-B2N1 are 12.1 kW, 64 Nm, and 29 A, respectively. To cool the motor during operation, a set of axial blower fans directs air current to flow from the motor’s rear side to the shaft side. Based on the same datasheet by Rexroth, these cooling fans require a 230-volt supply. In terms of its output shaft, the 2AD104D-B35OB1-FS0B-B2N1 incorporates a complete balanced key. 

Aside from the mentioned features, another strong characteristic of the 2AD104D-B35OB1-FS0B-B2N1 is its noise level. During normal performance, this motor model generates a moderate noise level at 70 decibels. For comparison, normal conversation levels at a busy restaurant range from 60 to 70 decibels. For an industrial motor, this sound level is impressive. Other motor characteristics, features, installation guidelines, and precautions may be further explored in Rexroth’s 2AD documentation.
