MDD065B-N-040-N2M-095PL0
The MDD065B-N-040-N2M-095PL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. With motor size 065 and length code B, it uses a compact housing that fits easily in multi-axis assemblies. The motor works with digital drive controllers to convert commanded current into precise rotary motion for positioning, indexing, and light torque duties in automated production equipment. This operating role makes it suitable for compact handling units, indexing tables, and other servo axes that need repeatable movement with fast response. Its compact format also supports installations where available mounting space is limited around adjacent machine components.
At standstill the motor can deliver 1.5 Nm of continuous torque, which is the load it can hold without excessive heating under rated conditions. During operation it reaches a nominal speed of 4000 rpm, allowing high-speed indexing when the connected drive supplies the required frequency. A centering diameter of 95 mm aligns the housing accurately to the machine frame for proper shaft concentricity. Power and feedback cables exit on the left side, and a plug-style connector combines the electrical terminations in one connection point. That cable orientation can simplify routing in machines where conductors must stay clear of guards, slides, and moving tooling. Standard dynamic balancing helps reduce vibration as speed increases and supports stable operation during frequent start and stop sequences.
Position feedback is provided by an integrated multiturn absolute encoder, which reports rotor angle over multiple revolutions and removes the need for an external homing routine after startup. That information is transmitted through digital servo feedback, allowing the drive to maintain stable closed-loop control without analog drift. The output shaft uses a keyway so torque can be transferred positively to pulleys or couplings, and a shaft seal helps protect the front bearing from dust and lubricants. Because the motor has no holding brake, stationary load retention must be provided by the drive or by external mechanical means. The standard housing and the shaft-end arrangement without a side B extension help the motor fit into compact pick-and-place axes.
