Product Description:
The MKD112B-073-KG0-AN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As a permanent-magnet synchronous unit, it supplies controlled rotary motion to machine axes and handling modules in automated lines. Its resolver-based feedback supports closed-loop positioning, allowing the drive controller to match programmed profiles with minimal error during repetitive industrial cycles. In automated equipment, it can serve feed axes, transfer stations, and positioning assemblies that require consistent motion from one cycle to the next.
The motor develops a continuous torque of 28.0 Nm at standstill, giving adequate holding force for medium-inertia loads without overheating. Coupling accuracy to surrounding mechanics is aided by a centering diameter of 130 mm and a square mounting flange that measures 192 mm across. These mounting dimensions help seat the housing accurately against machine surfaces and couplings. The motor is sealed to IP65, so dust ingress and water jets do not affect operation in standard production cells. Combined with system precision of ±8 angular minutes, the integrated resolver feedback supports repeatable positioning across the full speed range. The motor is supplied without a holding brake, so any static load retention must be achieved through external clamping or drive torque.
Electrical and mechanical interfaces are arranged on the A-side, where an output connector carries power and signal lines. This arrangement keeps the connection area on one end of the motor body. The motor uses a plain shaft with a shaft seal to help protect the bearing area from contamination and lubricant migration. The insulation system meets class F limits, supporting winding temperatures up to 155 °C while operating in ambient conditions of 0 to 40 °C. Size code 112 and length code B identify the stator stack dimensions inside the motor housing, and the absolute position detector retains counts beyond 4096 revolutions for multi-turn feedback.
