Product Description:
The 2AD132D-B35OB2-AS11 Asynchronous Servo Motor is designed for high torque, stable operation and dependable braking performance.
This 2AD132D-B35OB2-AS11 servo motor from Bosch delivers a nominal torque of 140 Nm at a nominal voltage of 290 V. This enables consistent performance in high demand applications. Its rotor inertia is 0.118 kgm² that ensures smooth acceleration and deceleration during operations. The power connection of the motor is located at the top. It offers flexibility in positioning to suit diverse machine setups with flange and foot mounting construction. The motor is equipped with an integrated holding brake designed to maintain position when the motor is powered off. The brake provides a holding torque of 100 Nm that ensures secure static positioning under load. The brake has a moment of inertia of 0.002 kg·m² which influences its dynamic response characteristics particularly during acceleration and deceleration phases. The brake ensures safe and controlled system shutdowns. The brake mass is 4 kg. Its insulation classification is F which allows safe thermal performance. The motor has a thermal time constant of 55 minutes that supports consistent performance under continuous duty.
This 2AD132D-B35OB2-AS11 servo motor from the 2AD series operates within an ambient temperature range of 0 °C to 45 °C. The electrical safety is ensured through a minimum connection cross section of 16 mm². The acoustic performance of the motor is controlled to maintain an average sound pressure level (SPL) of 75 dB (A) during operation. This noise level is achieved specifically when the motor is driven using pulse width modulation (PWM) at a frequency of 4 kHz. The servo motor is engineered with strong braking and operational features for demanding drive systems.
Frequently Asked Questions about 2AD132D-B35OB2-AS11:
Q: How does the 2AD132D-B35OB2-AS11 handle sudden shutdowns in high-inertia systems?
A: The integrated holding brake delivers 100 Nm of torque with a braking energy of 30,000 Ws. It ensures rapid and secure deceleration under load, minimizing drift or overshoot.
Q: What thermal characteristics support long-duration loads in continuous operation?
A: This model includes a 55-minute thermal time constant. It resists thermal rise under continuous cycles and supports steady performance without triggering temperature faults.
Q: How responsive is the braking system in fast-stop applications using 2AD132D-B35OB2-AS11?
A: The brake activates with a 110 ms clamp and 140 ms release delay. These short timings enable precise motion halts, critical for safety in automated drive sequences.
Q: Can the motor sustain electrical safety in systems with high voltage fluctuations?
A: It requires a 16 mm² cable cross-section to maintain stable current flow. This minimizes electrical stress, ensuring insulation integrity under load and thermal cycles.
Q: What influences integration flexibility in compact multi-axis layouts using 2AD132D-B35OB2-AS11?
A: Its top-side power connection supports versatile cable routing. Combined with flange and foot mounting, it allows clean system integration in space-constrained mechanical assemblies.
