Frequently Asked Questions

What control implications arise from the motor’s four pole pairs and ~6.7 mH phase inductance?

The four pole pairs raise electrical frequency for a given mechanical speed for influencing current-loop bandwidth and PWM switching losses. Its 6.7 mH inductance eases current ripple and improves current regulation stability at the drive.

Why specify 6 L/min coolant flow on MKD112C-024-KP0-AN, and how does it affect duty envelopes?

The defined flow provides predictable extraction of copper/iron losses so thermal models can permit higher RMS torque without exceeding winding class-F limits. Its adequate cooling margin and short-term overload utilization widens before thermal foldback.

How does continuous torque at standstill (38 Nm) relate to peak torque (≈350 Nm) for MKD112C-024-KP0-AN in positioning cycles?

The continuous standstill torque sets sustainable static holding and low-speed contouring capability. Its peak torque defines short-duration acceleration or disturbance-rejection headroom. The thermal time-constant and cooling decide allowable on-time at that level.

What advantages does a keyed shaft with shaft seal offer in this series?

The keyway provides positive torque transmission and simplifies hub tolerance selection versus purely frictional joints. Its seal protects against lubricant ingress and particulates to support IP65 compliance at the output end in wash-down-adjacent environments.

What does the 130 mm centering diameter imply for machine interface compatibility and runout control?

The pilot diameter governs concentricity and shear-load transfer into the flange to minimize alignment error at the coupling. It also matches common DIN flange patterns used across European machine-tool and packaging frames.

Internal Product Review

The Bosch produces MKD112C-024-KP0-AN as a servo motor that combines resolver-based absolute sensing with a sealed keyed shaft and possess axial connectors. It delivers 38 Nm stationary torque at 2000 rpm of angular speed, while its peak torques value goes up to 350 Nm. This unit has a 130 mm pilot and achieves cooling through 6 L/min of integrated system to sustain high temperatures in automation.
