2AD134B-B05OB1-ES06-B2V1
The 2AD134B-B05OB1-ES06-B2V1 from Bosch Rexroth Indramat represents a robust addition to the 2AD 3-Phase Induction Motors series, engineered for demanding industrial environments. This AC Induction Motor delivers a nominal output of 12.0 kW at a rated voltage of 400 V and operates seamlessly at 50/60 Hz. Housed in a rugged IP65 enclosure, it provides complete protection against dust ingress and water jets for reliable field performance. With a compact overall length code of B and a motor size code of 134, it integrates easily into existing drive systems without compromising footprint or accessibility.
In terms of technical prowess, this motor incorporates a low rotor inertia (JM) of 0.054 kg·m² to optimize dynamic response and precise speed regulation. It draws a nominal current of 27.8 A at full load and features a flange mounting pattern (B05) with a concentricity tolerance compliant with DIN 42955-R. The shaft diameter of ø42 mm k6 and a shaft length of 110 mm ensure secure coupling, while the shaft type without shaft seal, balanced with entire key prevents misalignment under high torque. Vibration is held within grade R severity limits according to DIN ISO 2373, and the winding code ES supports efficient thermal management.
Operational reliability is further enhanced by its heavy-duty bearings, rated for extended service intervals, and a top-mounted axial blower cooling scheme that directs airflow from B to A. The blower delivers 1000 m³/h at 330 VA to maintain consistent winding temperatures, with a thermal time constant of 45 minutes for stable overload capability. Digital position feedback is provided via an integrated digital servo feedback device, enabling closed-loop control and rapid fault diagnostics. Absence of a holding brake simplifies maintenance while ensuring quiet operation with a measured noise level of 75 dB(A) at 1 m.
Integration into complex automation systems is straightforward thanks to power connection position Top and power connection direction To Side B, allowing flexible cabling in confined spaces. The motor’s shaft end (Side B) without shaft end design and omission of a holding brake reduce installation complexity. As an industrial-grade solution within Bosch Rexroth Indramat’s portfolio, the 2AD134B-B05OB1-ES06-B2V1 excels in pump drives, conveyor systems, machine tool spindles, and other high-duty applications that demand precision, durability, and ease of integration.
