Frequently Asked Questions
What is the significance of the holding brake torque of 70 Nm?
This brake secures the rotor under power-off or emergency stop, preventing uncontrolled motion. For the MSK101D-0450-FN, it ensures safety in vertical or heavy-load axis situations.
Why is the torque constant value relevant 1.32 Nm/A for 0450?
The torque constant links current to mechanical output torque, guiding drive sizing and current limits. For MSK101D-0450-FN-M2-AP2-RNNN, 1.32 Nm/A gives predictable torque behaviour under load.
What is the maximum allowable coolant pressure for MSK101D-0450-FN-M2-AP2-RNNN motor?
The coolant system of MSK101D-0450-FN-M2-AP2-RNNN motor must not exceed 3 bar at the motor’s cooling port to avoid internal damage or seal leakage. Bosch Rexroth specification imposes this limit for all FN variants.
How does the thermal time constant 100 min affect cooling design?
A large thermal time constant means the motor temperature changes slowly under thermal load, so transient heating is buffered. Cooling systems and control must account for that lag to avoid thermal overshoot.
What are the permissible radial and axial shaft loads for this MSK101D-0450-FN-M2-AP2-RNNN motor?
The axial load of MSK101D-0450-FN-M2-AP2-RNNN motor limit is 500 N; radial load limits vary with bearing geometry and shaft length. Exceeding these can degrade bearing life or misalignment precision.
