Product Description:
Bosch Rexroth Indramat designs the servo motor 2AD160C-B05OA2-BS03-A2V1 as a part of the 2AD 3-phase series for machine automation. Its frame size is specified as 160 mm and it is built for flange mounting arrangement according to DIN 42948. The motor’s power connection is positioned on the top of the housing and its terminal box directs the output cable to side A.
The 2AD160C-B05OA2-BS03-A2V1 motor possess a nominal power rating of 37-kW and its rated torque is 236 Nm at base speed. Its base operating speed is 1500 revolutions/minute, while its peak permissible speed can go up to 6000 revolutions/minute. This unit utilizes 90 A of effective current at rated load from a voltage source of 299 Veff across the three-phase system at frequency between 50/60 Hz. Its rotor moment of inertia is kg·m² that allows controlled operations in acceleration and deceleration state. The 2AD160C motor uses a suction mode axial blower for cooling that operates from a source of 400 or 460 V and its average airflow volume is 659.2 CFM. The blower requires about 220 VA of power and its air flow direction is from the B side to A side. The motor is designed with a thermal time constant of 65 minutes under continuous duty and its insulation class is specified as F according to DIN VDE 0530.
The 2AD160C-B05OA2-BS03-A2V1 motor comes with a single sided plain shaft without key and without shaft seal. It includes high resolution feedback system, with an angular accuracy of ±0.02 degrees for positioning. This motor lacks holding brake and integrates an NTC thermistor for winding protection. Its rotational motion is supported by built-in heavy-duty bearings and the unit’s vibration severity level is class R.
Frequently Asked Questions about 2AD160C-B05OA2-BS03-A2V1:
Q: What is the benefit of the NTC thermistor in this motor?
A: The NTC thermistor detects winding temperature changes quickly. It helps protect the motor from overtemperature faults by enabling accurate thermal monitoring.
Q: How does the ±0.02° angular accuracy of the feedback system support automation?
A: This high-resolution accuracy ensures precise positioning in servo control. It enhances repeatability and synchronization for applications like CNC machining and robotics.
Q: How do heavy-duty bearings extend the operational life of the 2AD160C motor?
A: These bearings withstand high radial and axial loads. They minimize vibration and wear, ensuring consistent performance over extended duty cycles.
Q: What role does the thermal time constant of 65 minutes play in this motor?
A: It indicates how long the motor can sustain heat before reaching critical temperature. This allows safer operation during overload or transient conditions.
Q: How does the vibration severity class R affect motor application?
A: The class R defines acceptable vibration limits for reliable operation. It ensures the motor functions effectively even under dynamic industrial loads.
