Product Description:
The induction motor 2AD160B-B35OR1-BS26-B2N1 is designed by Rexroth Indramat as a member of the 2AD family. It operates with a nominal power consumption of 30000 W and provides a continuous torque of 191.0 Nm. This motor possess a base angular speed of 1500 r/min and it reaches a peak value of 6000 r/min.
The 2AD160B-B35OR1-BS26-B2N1 motor features a rotational inertia of 1740 kg·cm² and it utilizes 72.0 A of rated current during normal conditions from a 305 VAC source. Its NTC thermistor protection prevents overheating by monitoring temperature levels within the motor and it can cope high thermal values due to its class F electrical insulation. This motor integrates digital feedback for precise rotor position monitoring and control. A key feature of this motor is the electrically released holding brake that ensures stationary position when required through its 70 Nm of holding torque and 40000 Ws of braking energy. The brake operates on a terminal voltage of 24 VDC and uses 2 A of current, while its inertia stands at 65 kg·cm². The 2AD motor has a top mounted terminal box with output direction configured towards side A for routing cables and it is equipped with standard bearing that supports a service life of 20000 h along with vibration severity of grade R.
The 2AD160B-B35OR1-BS26-B2N1 motor incorporates an axial ventilation blower that facilitates airflow from side B to side A with an average air supply of 659.208 CFM and it operates on 400 V at 50/60Hz or 460 V at 60 Hz. The motor functions at an average noise level of 75 dB(A), measured 1 meter away by 4 kHz PWM. It is accompanied by a balanced seal less shaft, with one sided coupling option.
Frequently Asked Questions about 2AD160B-B35OR1-BS26-B2N1:
Q: How does the NTC thermistor protection improve reliability of the 2AD160B-B35OR1-BS26-B2N1?
A: The NTC thermistor monitors internal temperature continuously and triggers protective shutdown if overheating occurs. This helps prevent thermal damage and prolongs motor lifespan.
Q: How does the axial ventilation blower impact performance in the 2AD160B-B35OR1-BS26-B2N1?
A: The blower ensures efficient airflow across windings, maintaining optimal operating temperature. This cooling method supports sustained heavy-duty operation without derating.
Q: Why is a holding brake beneficial in the 2AD160B-B35OR1-BS26-B2N1 design?
A: The electrically released brake provides mechanical retention when power is off, preventing load drift. It’s especially important for safety and positioning in vertical or safety-critical applications.
Q: How does digital feedback enhance control in the 2AD160B-B35OR1-BS26-B2N1 motor?
A: The digital feedback delivers precise rotor position data to the drive controller. This allows for accurate speed regulation and improved dynamic response in automation.
Q: What role does rotor inertia (0.174 kg·m²) play in the 2AD160B-B35OR1-BS26-B2N1 performance?
A: The higher rotor inertia provides momentum stability, smoothing load fluctuations. It ensures smoother torque delivery during transient acceleration and deceleration phases.
