MKD112B-058-GG1-BN
MKD Synchronous Motors
The Bosch Rexroth Indramat MKD112B-058-GG1-BN from the MKD Synchronous Motors series combines high-performance design with robust industrial features. It operates as a synchronous servo motor across 3 phases and delivers a rated power of 9.8kW at a rated current of 37.0A, providing dependable torque and dynamic response. The motor employs a GG1 winding with winding code 058, ensuring consistent electromagnetic characteristics under varying loads. Its digital resolver feedback (RSF) system offers precise position control for demanding automation tasks.
Mechanically, the motor features a plain shaft configuration with an integrated shaft seal to prevent contaminant ingress and sustain long service intervals. Continuous torque at standstill is rated at 28.0 Nm, supporting high holding loads without motion. An output connector type connection, mounted on side B, simplifies installation and reduces cabling errors. The square flange measures 192 mm with a centring diameter of 130 mm, matching standard mounting patterns and facilitating rapid integration.
Safety and environmental tolerances are bolstered by an insulation class F rating, guarding windings against thermal stress. A built-in holding brake provides 22 Nm of torque, electrically released at nominal 24 V for controlled stopping and load retention. With a compact motor length classification of B and a product weight of approximately 34 kg, this unit balances structural rigidity and manageable mass. Overall, the MKD112B-058-GG1-BN offers a turnkey solution for robotics, machine tools, and precision handling systems across diverse industrial applications.

Frequently Asked Questions
How does MKD112B-058-GG1-BN handle transients requiring high torque density?
It reaches 135 Nm maximum torque. That ceiling absorbs short overloads during acceleration or disturbance rejection, ensuring trajectory authority without forcing drive derates or nuisance trips.
What environmental thermal margin do the windings tolerate in MKD112B-058-GG1-BN?
It carries Insulation Class F. The higher allowable temperature supports longevity at elevated loads, preserving dielectric strength and reducing insulation fatigue during extended shifts.
How does phase configuration aid smooth torque in MKD112B-058-GG1-BN?
It is a 3-phase motor. The three-phase field yields low torque ripple and efficient energy conversion, supporting precise speed control across a wide operating range.
Which orientation consideration simplifies wiring in clusters on MKD112B-058-GG1-BN?
It provides Side B connection direction. Routing can be arranged to avoid crossover with neighboring axes, shortening harness runs and improving service access in dense cabinets.
What secures vertical axes during downtimes on MKD112B-058-GG1-BN?
It includes a 22 Nm holding brake. The brake locks the shaft when power is removed, protecting fixtures and maintaining positional reference before controlled restart.
