Resolver feedback gives a robust, high-temperature‐ and vibration-tolerant rotor position sensing method, enabling reliable commutation and vector control even under harsh conditions. It avoids optical sensor issues such as dirt, alignment drift, or signal dropouts.

That torque at zero speed means the motor draws current even when stationary, so the drive must supply enough current and have good cooling to avoid overheating during prolonged standstill operation. It also implies that thermal limits (winding, core losses) become critical when frequent holds are required in motion profiles.

Without a mechanical holding (blocking) brake, the motor cannot hold load if power is removed; for safety or precision retention during power loss, external brakes or mechanical locking must be provided. Also, in vertical or inclined axes, load drift must be prevented via external means.

No shaft seal means that dust, moisture, or contaminants may reach bearings or internal parts via the shaft end, so usage in dusty, wet, or dirty environments may require additional protection (covers, sealing boots). Maintenance intervals for bearings may need to be shorter, and lubrication must be checked regularly.

If there is no extended shaft end on Side B, then coupling or mounting gearboxes etc must be done on the Plain shaft on one side only, potentially limiting dual-access or through-shaft applications. It simplifies sealing or protection on the unused side but might constrain flexibility in divergent mechanical layouts.
