Product Description:

The MDD112C-N-020-N2L-130PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into controlled torque and position for machining centers, packaging lines, and other automated axes. Its design supports closed-loop motion in multiphase AC servo systems, where the motor must respond quickly to changing load demands without losing position accuracy. In automated lines, this type of motor is commonly used where contouring, synchronization, or repeatable point-to-point travel is needed. Because the motor is intended for servo operation, the drive can continuously compare commanded and actual motion values and correct small errors before they affect the machine process.

A centering shoulder of 130 mm aligns the flange with the machine frame, and standard dynamic balancing helps reduce vibration during operation. The motor can deliver 28.0 Nm of continuous stall torque, while its nominal operating speed reaches 2000 rpm for typical servo duty over a broad range of automated motion tasks. Frame code 112 indicates the stator size, and length code C indicates the medium body depth for this motor size. Power and feedback cabling exit on side B, which can simplify routing where machine space is restricted or where cable bends need to stay close to the housing. The medium body depth provides additional active length without forcing the installation space required by a larger frame.

Control fidelity is supported by digital servo feedback that transmits high-resolution rotor position data to the drive for fast loop closure and stable motion correction. The motor is supplied without a blocking brake, so holding torque at standstill must be provided by the drive or by external machine elements when required. Construction with a shaft seal helps limit the entry of contaminants at the output end during normal service. The keyed shaft supports direct coupling to pulleys, couplings, or timing-belt drives, and the connector interface keeps electrical connection points compact at the motor housing. Because the shaft end is provided only on the drive side, the motor fits inline mechanical layouts without a rear output extension.
