Product Description:
The 2AD164B-B35LR1-DS46-B2N1 Induction Motor is engineered for demanding industrial environments by Bosch Rexroth Indramat. Its dual flange and foot installation offers adaptable integration and its rotor inertia of 0.174 kg·m² ensures a balanced dynamic response. It functions at a nominal current of 53 A and it delivers reliable and high capacity output with consistent electrical efficiency.
The 2AD164B-B35LR1-DS46-B2N1 induction motor has a rotational velocity of 1250 rpm under full load at which it maintains consistent operational efficiency. Its vibration severity grade R corresponds to regular industrial limits and ensures the machine operates smoothly with minimal oscillation. Its rotor shaft is precisely balanced along its full keyway which improves uniform torque delivery and reduces imbalance. It is optimized for clean environments as it comes with no shaft seal. The module's ventilation is handled by an axial fan that propels air directly across its casing. Its fan runs on 400 volts and ensures efficient heat dissipation and sustained thermal performance. It has a torque rating of 200 Nm which suggests higher strength that makes it suitable for medium to heavy duty machinery. Its built-in encoder provides real time position and speed information digitally and its closed loop control mechanism enhances precision. It is designed to handle 26.2 kilowatts of power consistently which makes it capable of driving significant mechanical loads.
This 2AD 3-Phase induction motor integrated braking system provides 240 Nm of holding force to keep the shaft stationary when de-energized. Its terminal box or connection point for electrical input is situated on the left hand side of the unit. This motor uses conventional rolling element bearings that implies reliability under regular load and speed conditions. In this module, the cable exit from the connection box is oriented to the right side.
Frequently Asked Questions about 2AD164B-B35LR1-DS46-B2N1:
Q: What mounting flexibility does the 2AD164B-B35LR1-DS46-B2N1 offer for machine builders?
A: It supports both base and flange installation, allowing integration in horizontal and vertical machine frames. This dual option simplifies retrofitting or adapting to custom configurations.
Q: How does the motor’s 0.174 kg·m² rotor inertia affect acceleration control?
A: The moderate inertia allows smoother acceleration and deceleration, reducing mechanical stress during load changes. It’s ideal for systems requiring consistent speed transitions.
Q: Why is axial blower cooling important for this induction motor?
A: Axial fans provide directed airflow across the motor casing, enhancing heat dissipation. This prevents thermal overload during continuous or high-demand operation.
Q: How does the 240 Nm holding brake benefit vertical axis systems?
A: It holds the shaft in position when powered off, preventing backdrive. This is critical for vertical loads or safety stops during power loss.
Q: What challenges does a 53 A rated current pose for installation?
A: It demands correctly sized power cables, circuit protection, and drives. Inadequate planning could result in overheating or tripped breakers under load.
