Frequently Asked Questions
Can the holding brake on the MHD112A-058-NG1-AN be used for dynamic braking?
No, the holding brake is intended for stationary holding only, not for dynamic deceleration. Using it for motion braking may cause premature wear or failure.
What benefits does the plain shaft design offer in coupling applications?
A plain shaft enables flexible coupling options and easy alignment with gearboxes or load connections. It minimizes mechanical stress concentrations compared to keyed shafts.
How does the liquid cooling influence the motor’s lifespan?
Consistent liquid cooling reduces internal heat buildup, protecting windings and insulation. This significantly extends operational life under continuous-duty cycles.
Is the MHD112A-058-NG1-AN suitable for vertical mounting?
Yes, but proper support and braking must be ensured to counteract load weight. The integrated holding brake provides reliable torque retention when power is removed.
How does the shaft seal contribute to motor performance?
The shaft seal prevents coolant or dust ingress into the bearing housing. This maintains lubrication integrity and reduces maintenance frequency in harsh environments.
