Frequently Asked Questions
What thermal advantages does the MKD112C-058-KP3-AN’s standard water cooling confer compared with purely convection-cooled variants?
The liquid heat extraction lowers winding/iron temperatures at equivalent load for enabling sustained operation at 20 A without derate in dense cabinets. Its reduced thermal drift helps maintain tight servo gains over extended duty cycles.
Why pair a 70 Nm holding brake with a 38.0 Nm continuous stall torque on MKD112C-058-KP3-AN?
The brake’s higher static torque secures vertical or overhauling loads during power loss or E-stop. It decouples load retention from electromagnetic torque production, preserving axis position without energizing the motor.
How does the keyed, sealed shaft on MKD112C-058-KP3-AN affect coupling design and ingress protection?
The keyway provides positive torque transmission without shrink-fit, easing serviceability. The shaft seal limits coolant and dust ingress at the bearing, prolonging lubricant life and minimizing runout growth.
What field-weakening considerations apply when running MKD112C-058-KP3-AN near 4500 rpm while preserving resolver accuracy?
Limit d-axis current to maintain demagnetization margins and voltage reserve. Recalibrate velocity observers at high speed; ensure resolver-to-digital tracking bandwidth handles increased electrical frequency without count slip.
How does the “058” winding code influence drive DC-bus sizing and regenerative energy handling on MKD112C-058-KP3-AN?
The winding constant sets back-EMF and current demand versus speed; confirm DC-bus voltage aligns with the 4500 rpm corner. Provide sufficient braking resistor capacity or shared-bus absorption for decel-intensive motion profiles.
