Without forced cooling, torque output must be derated under high ambient or continuous high-load conditions to avoid overheating. In harsh or confined installations you’ll need to verify that thermal limits are not exceeded.

Without a brake, any external load or gravity force must be managed by the drive or external mechanical locking. For vertical or safety-critical axes, you’ll need a separate mechanical brake or fail-safe holding method.

Yes — the torque rating is net sustained output (after internal losses), so you should plan your motor sizing on that delivered torque to ensure margin for friction, bearing drag, and coupling inefficiencies.

At higher speeds, the voltage limit of the drive and back-EMF will cap achievable torque, so continuous torque will drop as speed increases. You must refer to the motor’s torque-speed curve in the drive manual for safe operation margins.

The shaft seal helps protect the interior from contamination and fluid ingress, which is useful in dusty or splash-prone environments. However, the lack of a side B shaft means no secondary output — you’ll need to adapt your mounting or coupling accordingly.
