Product Description:
Bosch Rexroth produces the brakeless induction motor 2AD160C-B05OA2-BS03-B2N1 for spindle applications. It is 160 mm in size and its designed supports flange mounting due to the B05 configuration. This motor is accompanied by a mechanical key balanced shaft that measure 55 mm in thickness x 110 mm in length, while it does not possess a protective imposed seal and omits any assembly mounting on its side B.
The 2AD160C-B05OA2-BS03-B2N1 servo motor features an integrated axial ventilation blower that is configured in a suction mode with A to B direction of air and it functions on a 176 W power from a supported 3 x 400/460 V AC independent input source to deliver a continuous airflow volume of 659 CFM for thermal stability. Its power connection point is located above the housing and it directs cables toward the motor's A side. The unit operates with a nominal power consumption of 37.0 kW and provides a rotational speed of 1500 RPM normally, while its peak angular speed can go up to 6000 RPM. It generates a steady turning effect of 236.0 Nm under rated operating conditions and requires a voltage source of 299 V AC, while utilizes 90.0 A of current. The 2AD160 servo motor is dynamically balanced according to ISO vibration class R and it uses standard radial bearings with 20000 h of life expectancy to operate reliably with reduce maintenance needs.
The 2AD160C-B05OA2-BS03-B2N1 servo motor is presented with a high-resolution feedback encoder that is integrated into the housing and it provides an absolute accuracy of ±0.02° along with a relative accuracy ±0.01′ to eliminates the need for external encoders or incremental sensors. The 2AD160 servo motor’s internal NTC sensor monitors winding temperature in real-time and triggers thermal shutdown automatically via drive interface.
Frequently Asked Questions about 2AD160C-B05OA2-BS03-B2N1:
Q: How does the key-balanced shaft enhance performance in the 2AD160C-B05OA2-BS03-B2N1?
A: Dynamic balancing of the keyed shaft minimizes vibration at high speeds, improving rotational smoothness. This enables stable operation up to 6000 RPM.
Q: In what way does the axial-ventilation blower improve thermal management? (product code mentioned)
A: The 2AD160C-B05OA2-BS03-B2N1 uses axial blower suction to actively extract heat at 1120 m³/h airflow, maintaining optimal winding temperatures. This allows sustained power delivery without thermal throttling.
Q: What advantage does ±0.02° absolute encoder accuracy provide in the 2AD160C-B05OA2-BS03-B2N1?
A: High precision feedback ensures highly accurate position control and repeatability. It eliminates the need for external encoders and minimizes cumulative error over complex motion profiles.
Q: How does the NTC winding-temperature sensor protect the motor?
A: The internal NTC monitors winding temperatures in real time and triggers thermal shutdown via the drive if thresholds are exceeded. This prevents overheating and prolongs the motor’s lifespan.
Q: Why are standard radial bearings rated for 20,000 h life chosen here?
A: They offer a good balance between cost, maintenance interval, and reliability in high-speed rotary systems. 20,000 hours caters to extended uptime in demanding spindle applications.
