MDD041A-N-100-N2K-050MA0
The MDD041A-N-100-N2K-050MA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for digital drive controllers and converts commanded current into high-speed rotary motion for compact handling, packaging, and assembly axes. The motor uses size 041 with motor length code A, giving it a compact housing for tightly packed multi-axis equipment. Its standard housing profile follows the small-frame layout commonly used where installation space is limited.
A centering diameter of 50 mm aligns the flange with mating machine frames, and factory balancing to the standard grade helps reduce residual vibration at speed. Power and feedback conductors exit on Side A through a single connector, allowing a consistent cable path along the axis carrier and keeping connections grouped on one side of the housing. The motor provides 0.64 Nm of continuous standstill torque, which supports stable position holding during commanded stops. It can reach a nominal speed of 10000 rpm for fast indexing cycles. The shaft has no side B extension, and the front seal is omitted, so external sealing is needed when fluid ingress is possible.
An integrated absolute encoder supplies multi-turn position information to the drive, while separate resolver feedback tracks rotor angle in real time for current vector alignment. This feedback combination supports accurate position tracking and stable motor control across changing speeds. The motor is supplied without a blocking brake, so holding force during power-off states must come from the mechanical system or from available drive torque when the application permits it. Motion is transmitted through a keyway, which helps prevent shaft slippage during repetitive acceleration profiles. This arrangement suits lightweight tooling and other axes that need accurate registration, compact installation, and dependable feedback.
