Product Description:

The MDD041B-N-100-N2K-050MA1 is a synchronous motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers. As part of the MDD Synchronous Motors series, it converts controlled electrical power into precise rotary motion for positioning and velocity tasks in automated machinery. The motor interfaces with compatible Indramat drives for closed-loop regulation in assembly, packaging, and material-handling axes. This allows the drive to track commanded position and speed during repeated starts, stops, and direction changes.

The centering land measures 50 mm, and the winding stack uses length code B so the housing fits narrow mounting frames. When energized, the rotor can sustain a continuous standstill torque of 1.35 Nm, giving the axis stable holding force while thermal limits are respected. Dynamic applications also benefit from a top speed of 10,000 rpm, which supports short cycle times in pick-and-place or spindle duties. Power, feedback, and brake conductors exit on Side A through a single industrial connector, helping keep cable routing compact and orderly. An integrated absolute encoder sends position data to the drive, so external transducers are not required.

The motor is equipped with a blocking brake that provides 1.2 Nm of holding torque, helping prevent shaft rotation when power is removed. It also supports resolver feedback, which provides sinusoidal position and speed signals for drives that use resolver-based commutation. The shaft uses a keyway profile for positive coupling to pulleys or gears, and the standard shaft end is provided only on the drive side. Because the output journal is specified without shaft seal, the motor should be installed in dry areas or used with an external sealing element. Standard balancing helps reduce vibration at nominal speed, and the size-041 frame keeps overall mass low for compact machine layouts.
