Product Description:

The MDD041B-N-100-N2K-050PB0 is a small-frame synchronous servo motor from Bosch Rexroth Indramat and is part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive current into rapid rotary motion for positioning and speed regulation tasks in automated machinery. The model carries integrated motor feedback, so the controller receives precise rotor angle information without an external sensor. A keyway shaft transmits torque directly to couplings, and the housing is supplied in a standard form factor suited for compact machine installations.

The motor has a continuous standstill torque of 1.35 Nm, so it can hold that load continuously without exceeding its thermal limits. High-speed operation is possible because the rated shaft speed reaches 10,000 rpm, allowing short cycle times in pick-and-place axes. Precise centering during installation is provided by the 50 mm pilot diameter, and standard balancing keeps residual vibration low for coupling to light-inertia loads. For position control, the motor uses resolver feedback, which supplies analog sine-cosine signals that resist electrical noise. Ingress at the output end is limited by a shaft seal that helps prevent lubricant migration and dust entry.

All electrical terminations exit on the drive side because the power and feedback connectors are oriented on Side B. The mating plugs use the circular connector interface used in this series, which supports orderly cable routing. The motor is delivered without a blocking brake, so any static load must be held by the drive or a separate mechanical lock. Dimensional coding identifies the frame as size 041 with a rotor and stator stack designated by length code B. A single-ended shaft arrangement omits an opposite-side extension, which reduces overall length and helps preserve sealing at the drive end.
