2AD 3-Phase Induction Motors
2AD132D-B35LB1-AS23-A2N1, Bosch Rexroth Indramat, 2AD 3-Phase Induction Motors series offers a robust 20 kW three-phase induction motor operating at 400 V AC. This unit delivers a rated speed of 1600 rpm and accelerates to a maximum speed of 5000 rpm for demanding variable-speed applications. Its IE3 Efficiency class rating ensures premium efficiency and lower energy consumption over extended operation. Designed for industrial automation, it excels in heavy-duty processes with high torque and minimal maintenance.
Equipped with a Rated Current: 45 A rating and a Shaft Diameter: 38 mm smooth shaft, the motor provides up to rated torque of 120 N·m and a peak torque capability of 350 N·m. Cooling is handled via an external fan (IC416) in a Fan-cooled configuration to maintain optimal temperatures. The motor is housed in an IP55 Protection Class enclosure and accommodates ambient temperatures from -20°C to +45°C. Dual-mode Flange and foot mounting with an IM B5 flange-mounted design and Power Connection Position: Left (view from front) simplifies installation in tight spaces.
Integration into automation lines is streamlined by features such as electrically released Brake and high-resolution motor feedback for precise control. Standard Bearings and a Vibration Grade R rating ensure smooth, reliable operation under sustained loads. The motor’s rugged construction and Class H insulation deliver exceptional reliability in harsh industrial environments. With its combination of high efficiency, flexible mounting, and robust specs, the 2AD132D-B35LB1-AS23-A2N1 is ideal for process drives, conveyors, compressors, and other critical industrial applications.

Frequently Asked Questions
What does the IE3 efficiency rating of the 2AD132D-B35LB1-AS23-A2N1 imply for energy use?
IE3 indicates a high-efficiency motor, reducing energy losses during continuous operation. This leads to lower electricity costs and less heat generation in demanding industrial cycles.
How does the motor's IP55 enclosure affect its installation environment?
IP55 ensures protection against dust and low-pressure water jets, allowing installation in moderately dusty or damp environments. However, it's not suitable for fully submerged or high-pressure washdown areas.
Can the 2AD132D-B35LB1-AS23-A2N1 operate reliably in high-speed applications?
Yes, with a max speed of 5000 rpm and peak torque of 350 N·m, it supports high dynamic loads. This makes it suitable for applications like spindles or variable-speed conveyors.
Why is the smooth shaft design significant for coupling selection?
A smooth shaft requires precision-fit couplings or clamping hubs to avoid slippage. It also enables quieter, backlash-free power transmission in precision machinery.
What are typical signs of vibration issues in motors like the 2AD132D-B35LB1-AS23-A2N1?
Excessive noise, heat, or bearing wear may indicate misalignment or resonance. The motor’s vibration rating helps ensure smoother operation and longer bearing life under constant loads.
