Product Description:
The Bosch Rexroth Indramat induction motor 2AD160C-B35OB2-BS11-B2V1 is constructed with B35 configuration that offers both flange and foot mounting. It handles cooling through an integrated axial blower that directs air from A to B side and its air delivery is approx. 0.3111 m³/s. The blower requires 220.0 VA from an AC input of 3 x 400 V at 50/60 Hz or 3 x 460 V at 60 Hz.
The 2AD160C-B35OB2-BS11-B2V1 motor operates on a 299 V source and consumes a nominal power of 37000 W at rated conditions. Its torque at nominal speed is 236.0 Nm and its normal load current draw is 90.0 A. This motor possesses an angular rated speed of 1500 r/minute and its equipped heavy performance bearings can attain a maximum operating speed of 6000 r/minute. It features a holding brake that is electrically engaged type with torque capacity of 130 Nm and it operates on 24 V. The brake has a release delay of 120 ms and clamp delay is 90 ms, while its working capacity is specified as 40000 Ws. The 2AD160C motor’s output shaft is keyed and balanced without sealing ring. Its key dimension is 16 mm x 10 mm x 80 mm in accordance with DIN 6885-A. It uses a terminal box located above the body for electrical connectivity and its minimum cable cross section requirement is 2 AWG.
The 2AD160C-B35OB2-BS11-B2V1 motor is presented with an insulation class of F and its balance classification R provides minimum vibrations with a severity level of 1.8 mm/sec at rated speed according to DIN ISO 2373. Its noise emission is 75 decibels that is measured at one meter and it weighs about 240 kg. The motor’s flange diameter is 350 mm and it uses PG-42 designation for cable outputs.
Frequently Asked Questions about 2AD160C-B35OB2-BS11-B2V1:
Q: How does the B35 mounting configuration benefit installation?
A: The B35 allows both flange and foot mounting that gives flexibility in system layouts and easier alignment in retrofit or modular designs.
Q: Why is the axial blower cooling direction significant?
A: Its air directed from A to B ensures uniform thermal distribution over the stator and rotor. It improves heat removal and extending insulation life.
Q: What is the advantage of vibration balance class R in this motor?
A: The class R balance keeps vibration low (1.8 mm/s) by reducing bearing wear and assuring smoother operation especially at high speeds.
Q: How does a 40,000 Ws brake capacity impact performance?
A: This energy rating ensures the brake can absorb the kinetic energy of the rotor during emergency stops without overheating or damage.
Q: What role do heavy performance bearings play in this motor?
A: The heavy duty bearings support high radial and axial loads, enabling reliable operation up to 6000 rpm in demanding industrial environments (applies to 2AD160C series).
