Product Description:
The 2AD160C-B35OR2-DD03-A2V2 motor from Indramat features a feedback system with absolute accuracy of ±0.020° and relative positional accuracy of ±0.010′. Its protection is ensured by integrated NTC thermistors embedded in the windings, which are monitored by the drive for overtemperature faults. This motor is supplied without a holding brake system.
The 2AD160C-B35OR2-DD03-A2V2 motor is constructed with B-35 design that combines flange and foot mounting for flexible integration. Its output shaft has a plain design that measures 110 mm in length and comes without a sealing ring. The unit has built-in heavy-duty bearings to handle higher mechanical loads and longer service life. Its vibration severity classification is level S according to DIN ISO 2373, which guarantees compliance with industrial vibration standards and its terminal connection is designed with a PG 42 cable entry. The 2AD motor’s dimensional specifications include overall length of 400 mm and it weighs 240 kg. It utilizes 46000 W of power and 109 A of normal operational current. This unit produces 220 Nm of torque and its nominal speed is specified as 2000 rev/min. It requires a 3-phase 316 V source to operates and its rotor moment of inertia is 2290 kg·cm² for rapid accel/deaccelerations.
The 2AD160C-B35OR2-DD03-A2V2 motor relies on its provided 330 VA radial blower for maintaining its ambient operatable temperature. Its blower operates from a three-phase independent AC supply of 400 V at 50/60 Hz or 460 V at 60 Hz and provides an average air flow of 659 CFM. The unit’ heat dissipation value is 65 minutes and its noise emission is measured as 75 dB(A), with ±3 dB(A) tolerance. It supports encoder mounting on its A side of the shaft only and its B side does not provide any assembly attachment.
Frequently Asked Questions about 2AD160C-B35OR2-DD03-A2V2:
Q: How does the plain output shaft design of the 2AD160C-B35OR2-DD03-A2V2 motor benefit its operation?
A: The plain shaft reduces mechanical complexity and ensures smoother torque transmission. It is ideal for coupling with precision drive systems that demand high alignment accuracy.
Q: Why does the motor use NTC thermistors embedded in the windings?
A: The NTC thermistors continuously monitor winding temperature to prevent overheating. This protection mechanism extends motor life under continuous or heavy load operations.
Q: Why is a separate three-phase supply used for the radial blower in this motor?
A: Its separate blower supply ensures uninterrupted cooling even when the motor is idle. This maintains stable thermal conditions and prevents insulation degradation.
Q: What is the advantage of rotor inertia of 2290 kg·cm² in the 2AD160C-B35OR2-DD03-A2V2 motor?
A: The high rotor inertia allows smoother acceleration and deceleration. This feature supports precision control in high-speed machining or repetitive duty applications.
Q: How does the B-35 design of the 2AD160C-B35OR2-DD03-A2V2 motor enhance installation flexibility?
A: The B-35 configuration combines flange and foot mounting. This allows integration into both vertical and horizontal machine setups without redesigning supports.
