Product Description:

The MDD112B-N-020-N2M-130GB0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for positioning and speed-controlled axes in automated machinery. The B-length, size-112 housing uses the standard mechanical outline of this motor platform, which helps it fit established machine layouts. In packaging equipment, material handling systems, and other coordinated motion applications, the motor supports closed-loop axis control with accurate response to changing load conditions.

A centering pilot of 130 mm aligns the flange to the machine interface and helps maintain consistent shaft positioning during installation. Electrical power and feedback connections exit on Side B, which can make cable routing more direct when the driven load is arranged on the opposite side. The motor provides 17.5 Nm of continuous standstill torque, giving stable holding capability during dwell periods and controlled indexing. Its rated speed is 2000 min⁻¹, so the motor can support steady operation across common servo duty ranges before higher-speed operation becomes voltage-limited. The output uses a plain shaft, which is suited for clamping couplings and other friction-based connections without a keyed interface.

Position feedback is handled by an integrated multiturn absolute encoder with digital servo feedback, allowing the drive to track shaft position over multiple revolutions and restore position data after power cycling. This arrangement supports accurate interpolation, stable loop control, and quick return to operation where an external reference move is not preferred. A shaft seal is fitted at the output end to help retain lubricant and reduce the entry of contaminants near the bearing area. The motor is supplied without a blocking brake, so any power-off holding function must be provided by the machine system. This layout is well suited to applications that rely on drive-controlled motion, consistent feedback quality, and a compact mechanical interface.
