Product Description:
The MKD071B-061-GG3-KN is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. This electromagnetic actuator converts drive current into controlled rotary torque for positioning and speed-regulated tasks in automated machinery. Its frame design, electrical winding, and integral feedback system allow it to couple directly to Indramat digital drives, forming closed-loop axes for packaging, material handling, or machine tool spindles where repeatable motion and moderate load inertia are required. Because it is a synchronous motor, the connected drive can regulate torque quickly during starts, stops, and reversing moves. This supports stable motion when process speed changes or when the driven load varies through a repeated cycle.
Mechanical interface data show how the unit fits into a machine frame. A centering pilot of 95 mm ensures concentric alignment with the mating flange, while the square mounting pattern is based on a 115 mm flange size that matches standardized gearbox and cradle dimensions. The motor develops a continuous standstill torque of 8.0 Nm; this is the load it can hold without overheating when the rotor is locked. Electrical behavior is characterized by winding code 061, which corresponds to the voltage constant used by the drive for commutation. All power and signal leads exit on Side B, providing predictable cable routing inside enclosures. This cable orientation can also help keep the connection path clear of adjacent machine structures in compact axis layouts.
In operation, the resolver provides resolver feedback, giving relative position data that the drive converts to absolute values after homing. The motor belongs to size class 071 with length code B, a combination that balances rotor inertia against compact overall length for space-limited axes. Output power is delivered through a plain shaft, and a shaft seal is installed at the housing exit so lubricants or coolant cannot penetrate the stator cavity. A built-in holding brake is included, allowing the axis to maintain position during power loss. The sealed connection box provides top-access terminations for phase conductors and sensor wiring. This arrangement keeps electrical connections grouped in one protected location and supports orderly routing inside the machine.
