Frequently Asked Questions

What practical benefits does the 1.0 Nm holding brake provide in vertical applications?

The 1.0 Nm holding brake ensures that loads remain stationary when the motor is powered off, preventing unintended movement in vertical applications like lifts and gantries. This feature enhances safety and reliability in systems where load stability is critical during power interruptions.

How does the resolver feedback system contribute to the motor's performance?

The resolver feedback system offers high accuracy in rotor position and speed control, crucial for applications requiring precise synchronization. This system enhances performance in tasks such as robotic arm articulation and high-precision CNC operations.

What are the implications of the plain shaft design without a side-B shaft end?

The plain shaft design without a side-B shaft end simplifies the motor's construction and reduces potential points of failure. This design is advantageous in applications like direct-drive systems where additional shaft ends are unnecessary.

How does the 40 mm centering diameter affect mounting and alignment?

The 40 mm centering diameter ensures precise alignment during installation, reducing the risk of misalignment-related issues. This feature is beneficial in applications such as conveyor systems and automated assembly lines where alignment accuracy is crucial.

What are the advantages of the standard housing in various industrial applications?

The standard housing provides a balance between durability and ease of integration, making the motor versatile across different industrial applications. Its robustness is suitable for environments like automotive assembly lines and textile manufacturing where reliability is essential.
