Product Description:
Bosch Rexroth Indramat produces the MKD071B-035-KG3-KN, a servo motor in the MKD Synchronous Motors series. The unit delivers closed-loop rotary motion for CNC machinery, packaging lines, and other equipment that requires accurate speed and torque regulation. By coupling to a digital drive controller, the motor converts command signals into controlled mechanical rotation and serves as a primary actuator in industrial automation cells. Its mechanical outline follows the series footprint, allowing it to fit modular machine frames that use the same motor envelope.
The stator housing is machined for a centering diameter of 95 mm, allowing concentric alignment of the flange to the driven axis without additional bushings. A square flange measuring 115 mm provides the bolt pattern used for gearboxes or direct-drive mounts. At standstill, the electromagnetic winding sustains 8.0 Nm of continuous torque, so position can be held under rated current without overheating. Power and feedback cables exit on side B, and the molded connection box provides strain relief while separating high-voltage and signal terminals. Electrical characteristics correspond to winding code 035, which matches the motor with compatible drive inverters for the required voltage constant and rated current.
Mechanical holding is augmented by a holding brake that engages automatically when the drive is de-energized, helping prevent load drift on vertical or indexing axes. Rotor position is measured by resolver feedback, and the feedback electronics support absolute tracking for more than 4096 revolutions, eliminating the need for homing after power cycles. A plain shaft supports coupling with clamp collars or other friction-locking hubs, and a shaft seal is fitted to limit lubricant egress and particulate ingress. Overall dimensions correspond to motor size 071 and length code B, giving consistent sizing across the series.
