Product Description:
The MKD112B-073-KG1-RN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It converts electrical energy into controlled rotary motion for positioning tasks and speed-regulated axes in industrial automation systems. Permanent-magnet excitation and electronic feedback allow the motor to work with compatible digital drive controllers for accurate starts, stops, and speed changes. That controlled response is useful in conveyors, handling equipment, and packaging mechanisms where axis timing must remain consistent from cycle to cycle. Because the motor operates in a closed-loop system, the drive can correct for load changes quickly and keep commanded motion profiles stable during repetitive operation.
Mechanically, the stator seats against a centering shoulder of 130 mm, which helps align the motor with the machine frame. The flange width of 192 mm provides a broad mounting surface for torque transfer. At standstill, the motor delivers 28.0 Nm continuously, supporting low-speed holding and steady torque output. The housing is rated IP65 to resist dust and water jets, and the windings use insulation class F for thermal durability. Cables exit on the right through a molded power connector, and the plain shaft with a seal helps limit lubricant escape. The right-side connector placement can also simplify cable routing where space around the rear of the machine is limited. Frame code 112 with length code B gives the motor a medium-inertia layout for general industrial axes.
Resolver feedback supplies absolute multiturn rotor data for more than 4096 revolutions to the drive for position control. System accuracy is limited to ±8 angular minutes, which suits many indexing and contouring duties. An integrated holding brake can withstand 22 Nm of countertorque during power-off conditions, helping secure suspended or vertical loads. The permitted ambient temperature range is 0-40 °C, so the motor can operate at full performance on typical factory floors without added cooling. This arrangement gives the controller continuous position information while the brake supports load retention when electrical power is removed.
