Product Description:
The MDD112D-N-020-N2L-130PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power into controlled rotary motion required for positioning, indexing, and cyclic force tasks in industrial automation cells. The unit supports duties in material-handling lines, packaging stations, and machine tools. Its closed-loop operating concept allows the paired controller to regulate speed, position, and torque during repeated start-stop cycles.
At standstill, the rotor delivers a continuous torque of 38.0 Nm, allowing the axis to support static loads without thermal overload. During motion it synchronizes at 2000 rpm, a speed suited to medium-inertia tooling and transport duties. An integrated blocking brake applies 14.0 Nm of holding torque when the drive is disabled. Frame size code 112 identifies the stator outer diameter. Rotor position is monitored by digital servo feedback, allowing the drive to track shaft angle and correct deviations during operation. Standard rotor balancing keeps vibration within ISO limits at rated speed and helps protect bearings and couplings.
Electrical and cooling interfaces are located on side B, where a sealed connector carries power, brake, and encoder lines. The output shaft is machined with a keyway for positive torque transfer, and a factory-installed shaft seal protects the front bearing against emulsified coolant. Accurate concentric mounting is achieved by a centering pilot of 130 mm. The active stack length code D corresponds to the motor’s axial dimension and thermal capacity. The standard housing resists common shop contaminants, and the unit is supplied without a secondary side-B shaft end, so couplings remain confined to the drive side. This layout supports single-ended power transmission and keeps the machine interface focused on one output end.
