Frequently Asked Questions

How should you dimension the drive controller to support this motor’s thermal and peak currents?

The drive must supply surge current during acceleration without tripping, while also providing continuous current matching the motor’s thermal rating. Use the motor’s project planning manual to choose a drive with sufficient current margin and thermal capacity

In multi-axis systems, how important is centering diameter (130 mm) for mounting compatibility?

The 130 mm centering diameter ensures uniform mechanical interface and alignment with matching gearboxes, bearing units, or couplings, easing interchangeability. When combining motors of various diameters, aligning through the centering diameter reduces misalignment errors across axes.

How does standard balancing influence vibrational behavior at 4000 RPM?

“Standard balancing” typically meets DIN VDE class R, which suppresses mid-range vibration up to nominal speed, but might not suffice for ultra-high precision spindle applications. If your system demands low residual vibrations, you might need higher balancing or spin test matching.

How does the 11 Nm holding (blocking) brake impact axis safety and backlash?

The brake ensures the axis stays locked under up to 11 Nm when power is off, which is beneficial for vertical or suspended loads. However, its mechanical engagement may introduce a slight play or require periodic maintenance, so ensure your system tolerances account for that.

What is the practical consequence of “24 Nm continuous torque at standstill” for machine design?

It means the motor can sustain 24 Nm indefinitely without rotating, so in applications with long dwell times or heavy static loads, you can rely on it without overheating. Designers must still check thermal limits at higher speeds and during acceleration to avoid thermal overload.
