Frequently Asked Questions

Why is IP65 protection significant for MKD025A-144-KG0-KN?

The MKD025A-144-KG0-KN meets IP65 protection standards. This rating ensures the motor remains unaffected by dust and water ingress, preserving consistent functionality in harsh industrial settings with moisture or airborne particles.

How is cooling managed in the MKD025A-144-KG0-KN?

The MKD025A-144-KG0-KN uses natural convection cooling. This method stabilizes motor winding temperatures without additional fans, ensuring reliable thermal balance and reducing maintenance complexity across extended operational periods.

What effect does rotor inertia have in MKD025A-144-KG0-KN?

The MKD025A-144-KG0-KN carries a rotor inertia of 0.14 kgm². This ensures acceleration and deceleration remain balanced, providing stable motion transitions during fast operating cycles.

How does torque stability show in MKD025A-144-KG0-KN?

The MKD025A-144-KG0-KN delivers 0.4 Nm continuous torque at standstill. This torque ensures stability when the shaft remains fixed, keeping positioning accuracy constant during low-speed or idle operations.

Why is the MKD025A-144-KG0-KN supplied without a brake?

Connection direction on Side B dictates cable routing and bend relief. This orientation helps clear guards and adjacent equipment.
