Product Description:
The 2AD134B-B35OB1-ES26-B2N1 3-Phase Induction Motor is produced and manufactured by Bosch Rexroth Indramat for precision-based industrial applications. This induction motor’s construction type offers both flange and foot mounting to allow firm incorporation into various machine configurations that require flexible mounting options.
The 2AD134B-B35OB1-ES26-B2N1 motor provides a nominal power of 12 kW to handle tough continuous-duty cycles in environments requiring consistent torque delivery. This motor has an axial blower cooling type to ensure efficient temperature control under high operating loads. The base motor speed of this motor is 1500 min⁻¹ to provide a stable rotational velocity for machines requiring consistent motor output. The connection point of this motor for power is located on top to allow effective cabling management in confined spaces or enclosed installations. The winding design of this motor is designated as ES to optimize the electrical performance for efficient energy conversion and to maintain thermal limits within specified operating ranges. This motor consumes a nominal current of 27.8 Aeff to enable high current capacity without triggering protection cutoffs, which is essential for applications involving high inertia. This motor has built-in digital servo feedback that guarantees high-resolution positional data transmission.
The rotor inertia of the 2AD134B-B35OB1-ES26-B2N1 motor is rated at 0.054 kgm² to provide a right balance between torque responsiveness and speed stability. The output shaft of this motor is constructed without a shaft sealing ring, with a whole key balanced, and this motor weighs 90 kg. This motor features a standard bearing type, and it is rated with a vibration severity level of type R. This motor has a minimum cross-section cable connection requirement of 6 mm² to ensure electrical safety and compliance with current density standards during sustained load operations.
Frequently Asked Questions about 2AD134B-B35OB1-ES26-B2N1:
Q: How does the ES winding designation impact the motor’s thermal efficiency?
A: ES winding improves electromagnetic performance and limits heat buildup, which supports long operational life during sustained cycles.
Q: Why is axial blower cooling chosen over other cooling methods in 2AD134B-B35OB1-ES26-B2N1?
A: Axial blower provides directed airflow, enhancing internal heat dissipation and maintaining optimal motor temperature under continuous load.
Q: What is the role of the whole key output shaft without a sealing ring?
A: It allows direct mechanical coupling and smoother torque transmission, while the absence of a seal reduces friction but requires a clean operating environment.
Q: Why is digital servo feedback used in 2AD134B-B35OB1-ES26-B2N1 instead of analog systems?
A: Digital servo feedback provides higher resolution and more reliable data, ensuring better synchronization in closed-loop control systems.
Q: How does the motor’s 0.054 kgm² rotor inertia help dynamic loads?
A: It balances acceleration and deceleration, allowing smoother transitions and preventing overshooting in systems with variable speeds.
