Product Description:

The MDD041B-N-100-N2K-050FB0 is a small-frame synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for direct connection to digital drive controllers, it converts commanded current into controlled torque and speed for light rotary axes used in automated handlers, indexing tables, and compact testing rigs. The 041 size code and B housing length give the motor a compact form that fits installations where mounting space is limited. Its standard housing layout also helps it integrate into small servo axes that need precise motion and fast response. This arrangement suits applications that require accurate positioning in a limited installation area.

This model can sustain 1.35 Nm of continuous stall torque, so the shaft resists load while the controller holds position without overheating. A nominal speed of 10000 rpm supports fast cycle times where short move durations are critical. Mounting accuracy is aided by a centering pilot of 50 mm, keeping the stator concentric with coupled mechanics. Service connections emerge on side B, guiding cable ducts toward the rear of the motor housing to keep the front workspace clear. A single keyed connector carries both power and feedback conductors, reducing the number of separate cable entries at the motor.

An onboard integrated absolute encoder delivers position data immediately after power-up, and the built-in resolver feedback channel provides speed information for drive control. The unit is supplied without a blocking brake, so any static holding function must be provided by the servo drive or an external clamp, which also keeps the motor length shorter for tight installations. A plain shaft allows direct coupling to timing pulleys or miniature gearboxes. Because no shaft seal is fitted, the motor is best suited to clean, dry enclosures where low friction and minimal drag are preferred. Standard dynamic balancing helps limit vibration during operation, and the B length code increases the active stack enough to support the listed performance without increasing the mounting footprint.
