Frequently Asked Questions

How does digital servo feedback improve motor performance?

It enables precise communication with the drive controller for accurate speed and position control. This reduces lag and improves synchronization in automated systems.

Why is a centering diameter of 95 mm important during installation?

It ensures accurate motor alignment with couplings or gearboxes, reducing vibration. Poor alignment can increase wear and lower system efficiency.

How does continuous torque at standstill impact servo applications?

It determines how much load the motor can hold without rotation when energized. This is critical for holding positions under static load conditions.

What is the significance of a plain shaft with a shaft seal?

A plain shaft simplifies coupling to standard drive components. The seal protects against dust or fluid ingress, extending operational life in industrial settings.

In what scenarios is a holding brake torque of 3.0 Nm sufficient?

It suits medium-load applications such as conveyors or positioning axes. Higher-load vertical systems may require external mechanical brakes.
