Product Description:

The MDD041A-N-100-N2G-050PB0 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into mechanical rotation for compact positioning axes and light pick-and-place stations. The combination of a standard housing and internal balancing allows direct mounting in cabinets or on machine frames where high cycle rates and fast feedback are required.

For mechanical alignment, the front flange has a centering diameter of 50 mm, and the power and feedback connectors are oriented on Side B to simplify cable routing in densely packed enclosures. A continuous standstill torque of 0.64 Nm lets the axis maintain position without overheating during hold phases. The unit is supplied without a blocking brake, so external clamping devices are needed if power-off holding is necessary. Rotor position is monitored by resolver feedback, which gives the controller reliable angle data during rapid reversals. Standard dynamic balancing minimizes vibration at full speed, and the single-piece connector design shortens installation time while protecting the signal pairs from electromagnetic noise.

The motor reaches a rated speed of 10000 rpm, matching low-inertia tooling that demands short acceleration ramps. Its size code is 041, and the compact length identified by code A keeps the mass low for gantry or robot wrist mounting. A hardened shaft with a keyway transmits torque to pulleys or couplings, while an integral shaft seal blocks coolant splash and fine dust from entering the front bearing. The single shaft end, with no side B extension, and the standard housing geometry reduce the overall footprint while maintaining protection for the internal windings.
