Product Description:
The MKD041B-144-KP1-KS is a servo motor built by Bosch Rexroth Indramat within the MKD Synchronous Motors series. Designed for closed-loop motion control, it converts drive commands from digital controllers into precise rotary output for automated tooling, pick-and-place axes, and packaging lines. Its construction pairs a permanent-magnet rotor with stator windings associated with the 144 code, creating the magnetic coupling required for synchronous operation. This arrangement lets the motor respond predictably to changes in command speed and position, which is important in equipment that repeats short, accurate motion cycles.
At standstill, the motor supplies a continuous torque of 2.7 Nm, allowing stable holding or low-speed feed without thermal overload. The motor uses an 82 mm square flange and a centering diameter of 50 mm, giving direct interchange with standard planetary gearboxes and machine frames. The housing carries an IP65 rating, so dust ingress and water jets do not affect the stator windings or bearings. Position feedback comes from a resolver with integrated electronics that provides absolute data exceeding 4096 revolutions, and a system precision of ±8 angular minutes supports accurate interpolation in multi-axis systems. This feedback arrangement allows the drive to track rotor position continuously during synchronized motion. Rated performance is maintained in ambient temperatures from 0–40 °C, matching typical control cabinet and factory floor conditions.
The motor includes a holding brake that produces 2.2 Nm of static torque to secure loads during power-off sequences. It uses insulation rated to Class F, permitting winding temperatures up to 155 °C during cyclic peak operation. Power and feedback conductors exit on Side B through a sealed connection box, simplifying cable routing along linear guides. A shaft with a keyway transmits torque, and the fitted shaft seal limits lubricant migration from adjacent gear stages. The compact frame helps moving axes accelerate quickly and reduces the inertial load seen by the drive. Motor size 041 and length code B keep the overall package short enough for indexing tables and compact gantries.
