Product Description:

The MDD025C-N-100-N2G-040ML0 is a compact synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts commanded current into precise shaft rotation for small manipulators, feeders, and auxiliary machine axes. Its compact size suits installations where space is limited but fast and accurate motion is still required. This type of motor is commonly selected for applications that need repeatable positioning without a large mechanical footprint.

The motor’s nominal speed is 10,000 rpm, which permits direct coupling to low-inertia loads without overspeeding. Continuous torque at standstill is 0.90 Nm, which shows its ability to maintain position while the shaft is not moving. A centering diameter of 40 mm helps align the housing accurately in the machine frame and reduces radial misalignment during mounting. Cables exit on the left side, which can simplify routing when adjacent components are placed on the opposite side. All power, signal, and protective earth leads are grouped in one connector, reducing cable handling during installation. Position data is provided by resolver feedback, so the controller receives rotor angle information continuously and can regulate current accurately from zero speed up to the rated maximum.

The motor uses frame size 025, which keeps rotating mass low for quick acceleration in compact axes. Its length code is C, giving the active section a slightly longer stack to support stable output in this frame size. The single-ended shaft has a keyway for keyed couplings, and the absence of a side-B shaft extension helps keep the overall depth short. The housing uses standard convection cooling, so no external blower is required. The motor is supplied without a blocking brake and without a shaft seal, so the machine must provide load holding during power-off conditions and protect the front bearing area from contamination.
