Frequently Asked Questions
How does the axial blower cooling in the 2AD164B-B35OA1-BS46-D2N1 affect continuous duty performance?
The axial blower forces air directly over the housing, ensuring consistent heat dissipation. This allows the motor to maintain rated torque without thermal derating in prolonged operations.
What installation considerations arise from flange and foot mounting options?
These dual options provide flexibility for horizontal or vertical machine layouts. However, ensuring correct alignment and foundation rigidity is critical to avoid bearing stress.
How does the electrically released brake with 240 Nm torque benefit industrial use?
It holds heavy loads securely when power is off, preventing unwanted motion. The high torque capacity makes it suitable for vertical axis or safety-critical systems.
Does the digital servo feedback in the 2AD164B-B35OA1-BS46-D2N1 improve positioning accuracy?
Yes, digital feedback delivers precise rotor position data to the controller. This enhances synchronization and minimizes error in servo-driven applications.
Why is the 400V blower supply separated from the motor’s main power?
A dedicated blower supply ensures cooling even during low motor speeds or standby. This prevents localized overheating in partial-load operations.
