Frequently Asked Questions
How does the “natural convection and radial surface cooling” mode limit performance?
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.
What trade-offs arise from omitting a blocking (holding) brake in the unit?
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.
Does the 10.4 Nm continuous torque spec include losses from the encoder or bearing drag?
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 nominal speed (3000 min⁻¹), how does torque capacity degrade versus standstill?
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.
How do the shaft seal and absence of side B shaft end affect axis integrations?
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.
