Product Description:

The 2AD160C-B35OA1-BS03-D2V1 is a 2AD series servo motor from Bosch that is designed with a whole-key shaft orientation. Its shaft provides only one-ended support and omits any assembly at the B side, while it measures 4.33” in length and 2.17” in thickness. This motor is 33.11” in length as a brakeless unit and possess a 11.81” front face along with 12.20” rear side.

The 2AD160C-B35OA1-BS03-D2V1 motor has a nominal current requirement of 90 A and runs on a voltage of 299 V AC. Its moment of inertia is 2290 kg·cm² to support controlled functionally even at the highest achievable speed of 6000 r/minute. The motor is equipped with an axial blower of air flow direction from B to A side and it utilizes 176 W of power from a 3-phase source to provide 0.311 m³ per sec of air through the housing for maintaining ambient thermal range that is specified as 155 °C in accordance with class F. This 2AD induction motor uses 37000 W of power in normal load scenario and delivers 236 Nm of turning effect, along with a continuous speed of 1500 r/minute. Its thermal constant for heat dissipation is 65 minutes and it supports both feet/flanges mounting styles due to its B35 designation. The unit operates efficiently under ambient temperatures ranging from 0 °C to 45 °C.

The 2AD160C-B35OA1-BS03-D2V1 induction motor is equipped with a high-resolution encoder system for feedback that ensures accurate position detection. The unit possess vibration severity level of R to ensure stability and minimal operational disruption. It weighs 240 kg on its own and it comes with heavy class of ball bearing to support 20000 h of operational life expectancy.

Frequently Asked Questions about 2AD160C-B35OA1-BS03-D2V1:

Q: What benefit does the single-ended shaft orientation provide in the 2AD160C-B35OA1-BS03-D2V1?

A: The one-ended shaft simplifies installation by eliminating the B-side assembly, reducing alignment complexity. It also lowers maintenance and cost while preserving shaft rigidity under load.

Q: How does the axial blower cooling system enhance performance in 2AD160C-B35OA1-BS03-D2V1?

A: The built-in blower directs airflow from B to A, maintaining optimal temperatures even at high speeds. This active cooling supports continuous operation up to 1500 r/min without thermal shutdown.

Q: What advantage does the 65-minute thermal constant provide for 2AD160C-B35OA1-BS03-D2V1?

A: A long thermal constant means the motor’s temperature changes slowly, allowing better response to transient loads. This ensures thermal stability during rapid speed or torque fluctuations.

Q: How does the high-resolution encoder impact the 2AD160C-B35OA1-BS03-D2V1’s control precision?

A: It delivers fine-grained feedback for accurate positioning, reducing error in closed-loop control. This makes the 2AD160C-B35OA1-BS03-D2V1 ideal for high-accuracy tasks like CNC tools.

Q: What role does the 0.229 kg·m² moment of inertia play in the 2AD160C-B35OA1-BS03-D2V1?

A: A moderate inertia balances smooth torque delivery with dynamic responsiveness, enabling stable acceleration and deceleration. This is critical for high-speed operation up to 6000 r/min while maintaining control.
