Frequently Asked Questions
How does the winding code on MHD112C-035-NP0-LN influence electrical sizing and torque capability?
The winding code 035 maps to a 3000 min⁻¹ characteristic speed, 38 Nm standstill torque (natural cooling) and 1.37 Nm/A torque constant for guiding drive current and dc-bus requirements. Its rated speed is 2500 rpm with 167 Hz rated frequency for sizing filters and mechanics.
Why does the MHD112C-035-NP0-LN use HSF digital servo feedback, and what does “relative” imply?
The HSF provides high-resolution incremental signals for precise velocity and position loops with low latency. It’s relative axis requires a homing/reference move after power-down to establish absolute position.
What’s the impact of liquid-cooled housing (series feature) on thermal utilization for this motor family?
Its liquid-cooled housings in the MHD series remove heat efficiently to enabling higher continuous output and temperature stability under sustained load compared with natural convection. Its coolant-ready variants are documented across the family.
How does the IP65 enclosure of the MHD112C-035-NP0-LN affect installation environments?
The IP65 protects against dust ingress and low-pressure water jets, supporting use near coolants or airborne particulates typical of packaging lines and machining cells. It still requires appropriate cable glands and sealed connectors to maintain the rating.
What are the mechanical interface points and why do they matter?
The size-112 frame standardizes a 192 mm flange and 130 mm centering diameter for drop-in interchangeability across MHD112 variants. It eases retrofits and ensures concentricity for precision couplings and gearheads.
