Product Description:
The 2AD160B-B35RB3-BS03-B3V1 is a reliable induction motor by Bosch Rexroth Indramat. The product is designed for heavy industrial applications. It comes with surface-cooled asynchronous design.
The 2AD160B-B35RB3-BS03-B3V1 provides reliable power and durability. It belongs to the 2AD AC Induction Motors series. It has a frame size of 160 mm and a short length B housing. The motor comes with a B35 flange and foot mounting for easy installation. Cooling is provided by an exterior blower and surface ventilation. It performs well as a main spindle or servo drive motor in machine tools, packaging, forming, and printing machines. The rated torque ranges between 70 and 100 Nm, with a rated speed of 1500 rpm. Rated power ranges from 10 to 15 kW, while rated current ranges from 25 to 40 A. The maximum speed is 9000 rpm, but some encoders may limit it to 3500 rpm. The standstill torque equals the rated torque, resulting in stable performance. Noise emission is around 70 dB(A) measured at a one-meter distance. The operational temperature range is 0 to +40 °C. A sealing ring has been used to key the motor shaft. Heavy-duty roller bearings are installed on the A-side for further robustness. It provides vibration grade R according to ISO 2373. The insulation class is F, while the motor and blower have protection classes of IP65 and IP24, respectively. The motor has a thermal time constant of around 40 minutes. The mass ranges from 80 kg to 120 kg, depending on the winding and extras. The moment of inertia ranges between 0.03 and 0.07 kgm². Mounting positions are provided in both horizontal and vertical orientation.
The 2AD160B-B35RB3-BS03-B3V1 motor has CE and UL approvals, depending on the version. A holding brake can be incorporated with torque ranging from 100 Nm to 140 Nm, working at 24 VDC and with a release delay of 50 ms to 100 ms. Digital servo feedback encoders are available in both absolute and incremental configurations. It is unsuitable for cranes, elevators, medical, nuclear, food processing, and explosion-prone environments.
Frequently Asked Questions about 2AD160B-B35RB3-BS03-B3V1:
Q: How does the keyed shaft with sealing ring improve reliability?
A: The sealing ring prevents oil and dust ingress into the motor. This ensures stable shaft operation and reduces maintenance downtime.
Q: What advantage does insulation Class F provide in the 2AD160B-B35RB3-BS03-B3V1 Motor?
A: Class F insulation allows higher temperature tolerance without performance loss. It ensures thermal stability under heavy industrial duty cycles.
Q: How does digital servo feedback benefit the performance of this motor?
A: Digital feedback ensures precise speed and torque monitoring. It enhances accuracy in machine tool and automation processes.
Q: Why is vibration grade R used in the Bosch Rexroth Indramat 2AD160B-B35RB3-BS03-B3V1 Motor?
A: Vibration grade R minimizes structural resonance during operation. It ensures smoother rotation and protects connected machinery from stress.
Q: How does the thermal time constant of 40 minutes affect performance?
A: It allows the motor to handle short-term overloads without overheating. This improves operational reliability under fluctuating load cycles.
