Frequently Asked Questions
How does liquid cooling affect the performance of the MHD071B-061-BP3-UN?
Liquid cooling enables higher continuous torque output by maintaining thermal stability, especially in compact or enclosed installations. It also extends service life by reducing thermal stress on windings and bearings.
Is the 10.0 Nm holding brake sufficient for vertical axis applications?
Yes, the holding brake torque is typically enough to safely hold most vertical loads during power-off or emergency stop. Always verify with load calculations to ensure adequate braking capacity.
Can the power connectors on the MHD071B-061-BP3-UN be repositioned during installation?
Yes, the power and feedback connectors can be turned within a 270° range. This allows easier routing in tight spaces and improves cable management flexibility.
How does the flange size and centering diameter affect mounting compatibility?
The 115 mm flange and 95 mm centering diameter conform to common servo motor mounting standards. This ensures compatibility with a wide range of gearboxes and mechanical frames.
Why is continuous torque at standstill a critical parameter?
This value determines the motor’s ability to maintain load without overheating when stationary. It’s especially important in positioning and holding tasks under constant load.
