Frequently Asked Questions
What is the benefit of the plain shaft design on this motor?
A plain shaft avoids key-ways or splines, offering simpler coupling and less stress-concentration at the interface. This yields smoother coupling with servo gearboxes and can reduce torsional vibration.
Why is the holding brake torque of 6.5 Nm significant in the MDD090C-N-030-N5L-110GB1 motor?
The integrated brake ensures safe stopping and holding under power-off conditions, reducing the need for external brakes. It adds safety margin in robotic, indexing or vertical motion axes.
How does the 110 mm centering diameter improve installation flexibility?
The 110 mm mounting bore ensures standardised alignment and reduces vibration sensitivity, enabling drop-in replacement for earlier systems. It also facilitates modular coupling with flanges and gearboxes.
What role does the 2.7 mH winding inductance play on this motor?
The inductance of MDD090C-N-030-N5L-110GB1 motor influences current rise time and thus the servo responsiveness and control bandwidth. Lower inductance means faster current control and tighter dynamic performance in positioning axes.
In what specific applications is the MDD090C-N-030-N5L-110GB1 motor especially well-suited?
The motor’s high torque, feedback precision and brake make it ideal for robotics, packaging lines and CNC machinery where synchronous motion and reliable hold are mandatory.
