Frequently Asked Questions
What factors limit the usable torque below 24 Nm at high speed for this motor?
The available torque falls off with speed because back-EMF rises, reducing net voltage margin and current drive capability. Thermal limits and inductance also constrain how much current (and thus torque) you can sustain at high RPM.
How critical is brake torque matching (22 Nm) for safe load holding in vertical axes?
The brake must exceed the maximum potential gravitational torque plus a safety margin, so 22 Nm must outstrip worst-case load. If undersized, the brake can slip, so detailed static torque budgeting is essential.
In what scenarios would “standard balancing” be insufficient, and what’s the trade-off?
In high-speed spindles or ultra-precision systems, higher balance grades (e.g. ISO G1) may be needed to avoid vibration. The trade-off is extra cost and process complexity in balancing.
What electrical drive resolution do you need to fully exploit this motor’s digital feedback?
The drive should support at least the same bit-resolution (e.g. 17–23 bit or higher) as the encoder to avoid limiting control precision. Insufficient resolution will degrade control bandwidth and position accuracy.
How does the “continuous torque at standstill = 24 Nm” spec translate in real-world S-curve motion profiles?
That number indicates the maximum torque the motor can safely hold stationary under rated temperature. In motion profiles, you must derate dynamic torque due to heating, cooling, and transient current capabilities.
