Product Description:

The MKD071B-035-GG3-KN is a servo motor from Bosch Rexroth Indramat that belongs to the MKD Synchronous Motors series. As a rotary actuator for industrial automation, it converts electrical energy into controlled mechanical motion for positioning, indexing, and cyclic drives. The motor uses size code 071 with the B length variant, which suits medium-duty axes where space and torque density must be balanced. A plain shaft transmits torque directly into the machine, and an integrated holding brake secures the load when power is removed.

At standstill, the rotor delivers 8.0 Nm of torque, allowing the axis to resist process forces. Installation is aided by a 95 mm centering diameter that mates with mounting surfaces, while the 115 mm square flange sets the bolt pattern for standard gearboxes. The housing is rated IP65, which helps protect internal components from dust and water jets, and the stator’s electrical characteristics correspond to 035 for compatibility with MKD drives. Power and feedback conductors enter through a connection box on Side B, which can simplify cable routing inside cabinets. A shaft seal keeps lubricant in and contaminants out, and the built-in holding brake supplies size-dependent stopping torque.

The feedback system uses resolver feedback (RSF) to supply rotor angle data to the controller after an initialization move, supporting a control loop accuracy of ±8 angular minutes. Class F insulation permits winding temperatures up to 155 °C, supporting thermal stability during continuous duty. The motor operates in ambient temperatures from 0 to 40 °C without derating, giving flexibility for enclosure-mounted or open-machine installations. Typical uses include indexing conveyors, tool changer axes, and other medium-inertia loads that require repeatable positioning during extended production shifts.
