Product Description:
The MKD041B-144-KG1-KN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As a permanent-magnet AC unit, it converts electrical energy from a drive controller into rotary motion for positioning tasks in industrial automation. The motor uses a winding code 144 stator and is built in length B within the size 041 frame, giving machine designers a compact choice for medium-precision axes.
The mechanical interface is defined by a centering diameter of 50 mm and an 82 mm square flange, allowing direct coupling to gearboxes or load brackets without alignment adapters. Continuous torque at standstill is rated at 2.7 Nm; this is the maximum sustained output before thermal limits are reached when the rotor is locked. Connections are routed on the Side B of the housing through a connection box, simplifying cable exit inside tight cabinets. Rotor position is reported by a resolver feedback device that is integrated with the encoder electronics, enabling sinusoidal commutation and smooth low-speed control. The dedicated winding and compact stator laminations keep inertia low for rapid load acceleration.
A permanent-magnet holding brake supplies 2.2 Nm of static torque to keep vertical or overhung loads stationary during power loss. A positive-contact shaft seal blocks coolant and dust from entering the bearing cavity, so the motor can be mounted in splash zones without additional covers. The integrated electronics deliver Absolute (>4096 revs) feedback to the controller immediately after power-on, eliminating homing moves in multi-axis lines. A plain shaft transmits torque via friction couplings, reducing backlash compared to keyed fits and supporting high-resolution trajectory profiles.
