Product Description:

Bosch Rexroth Indramat’s MDD041A-N-100-N2K-050PB0 synchronous motor belongs to the MDD Synchronous Motors series and is intended for use with digital drive controllers in automated plant equipment. The unit combines the compact frame size 041 with a standard housing, giving it a lightweight, high-speed format that fits easily into existing machine layouts and cabling paths. By converting drive current into precise mechanical motion, the motor supports positioning and spindle tasks that require fast speed changes and stable closed-loop control. Its compact size also suits transfer units and other small axes where installation space is limited.

The rotor can reach a nominal speed of 10000 rpm, allowing short cycle times in pick-and-place or auxiliary spindle duties. At standstill it delivers 0.64 Nm of continuous torque, which is suitable for light indexing or clamping loads while keeping thermal stress low in the frame. Mechanical alignment is simplified by a centering diameter of 50 mm. All power and signal conductors exit through a sealed connector interface on Side B, which can help keep cable routing clear of the driven load. Position data are generated internally by integrated motor feedback, so the drive receives rotor information without separate external sensing hardware.

Speed and commutation signals are transmitted through resolver feedback, which offers good resistance to electrical noise in long cable runs. The shaft extension uses a keyway profile and includes a shaft seal, helping protect the bearing area from contamination near adjacent geared or belted components. The motor is supplied with no blocking brake, so holding torque must be provided by the drive or by an external clamp when power is removed. Standard dynamic balancing helps reduce vibration during operation. The A-length stator keeps the motor short, and the absence of a side B shaft end simplifies coupling to belt pulleys or miniature gearboxes in tight mounting spaces.
