Product Description:
The MKD041B-144-GP0-KN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Designed for integration with the company’s digital drive controllers, the unit transforms electrical commands into precise shaft rotation that positions grippers, tracks conveyor sections, or synchronizes compact tooling heads. Its size 041 frame and B length allow the motor to slide into tight cabinets without modifying existing mechanical envelopes.
At the mechanical interface, the motor presents a centering diameter of 50 mm and an 82 mm square flange, establishing concentric alignment with gearboxes or direct-drive mounts. The continuous torque at standstill is rated at 2.7 Nm, which defines how much static load the axis can hold while the rotor remains energized. A sealed resolver provides Resolver feedback; this analog sensor supplies sine-cosine signals the controller converts into absolute angle data for closed-loop control. Power, brake, and feedback leads exit on the rear housing because the connection hardware is oriented toward Side B, keeping cables clear of linear guides in many machines. A shaft seal is fitted to protect internal bearings from lubricant spray, and the winding set matches standard MKD drive parameters.
Electrical termination is performed through a dedicated Connection box, allowing shielded motor power and feedback cables to be landed without disassembling the endbell. The copper turns are identified by Winding code 144, so drive firmware can select current limits and commutation tables matched to the coil resistance and inductance. Torque is transmitted through a keyed shaft; the interface is specified as a Shaft with keyway for positive mechanical locking to couplings. For applications that reference incremental homing routines, the motor supports Relative position detection, and it ships without a holding brake to reduce mass and inertia in high-speed axes. Together, these features complete the motor’s electrical, mechanical, and feedback provisions.
