Product Description:

The MKD041B-144-GP0-KS is a servo motor built by Bosch Rexroth Indramat and placed within the MKD Synchronous Motors series. As a compact rotary actuator, it converts electrical energy from a corresponding drive into controlled mechanical motion for indexing tables, packaging axes, and other precision duties common to automated machinery. Its construction follows the requirements of industrial automation where accurate torque delivery, repeatable positioning, and sealed housings are required. Its compact format also suits machine sections where installation space is limited but precise motion is still needed.

Mechanically, the motor mounts through an 82 mm square flange, while the centering pilot of 50 mm helps keep radial runout within tolerance. At standstill, it supplies a continuous torque of 2.7 Nm, which is suitable for small pick-and-place heads or feed drives. The housing carries an IP65 rating, so dust and low-pressure water jets do not compromise the internals, and a shaft seal gives the bearings added protection. Operation is rated for ambient air from 0–40 °C, matched to Class F winding insulation that tolerates higher internal temperatures without insulation breakdown. The keyed shaft supports positive coupling, and the connection box at the stator exit helps simplify field wiring. Motor length code B and size 041 set the overall footprint and mass within the series.

Control performance centers on the integrated resolver feedback, which provides rotor angle information for drive-side commutation and supports relative position tracking over repeated turns. Combined with a system precision of ±8 angular minutes, the motor can hold commanded positions tightly when driven by a compatible controller. Because it is supplied without a holding brake, any static load must be secured by the drive’s torque or by an external mechanical lock. Power and feedback lines exit on Side B, keeping connectors clear of the driven load, and the specified winding code 144 aligns electrical resistance and inductance with standard MKD drives. This arrangement helps the axis remain responsive during reversals and short indexing moves.
