Product Description:

The MDD041B-N-100-N2G-050MA1 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts controlled current into servo torque for fast-cycling industrial axes such as feeders, light gantries, and small spindle stages. By integrating directly with Rexroth drive electronics, it provides closed-loop speed regulation that keeps tooling or transport mechanisms on set point even under varying mechanical loads.

This model reaches a nominal speed of 10000 rpm, enabling high surface velocities in compact machinery. At standstill it supplies 1.35 Nm of continuous torque, while a blocking brake contributes an additional holding capacity of 1.2 Nm to secure vertical or suspended loads during power-off states. Electrical terminations are arranged on Side A, and the power and feedback leads are brought out through a single connector to streamline cabinet wiring. Standard dynamic balancing minimizes vibration over the full speed range, and the housing is supplied in the standard enclosure style suited for general-purpose cabinet installations. The motor has length code B, and size 041 places it in the 40 mm frame class that fits into tight mechanical envelopes.

The mounting flange uses a centering diameter of 50 mm, and rotor position is reported through integrated resolver feedback for sinusoidal commutation accuracy. The output shaft is machined with a keyway and is the only shaft end provided, because the design is standard without a side B extension. A lubrication barrier is present, yet the motor is supplied without a shaft seal, so installation areas must be free of coolant spray or oil mist. The standard shaft end, combined with the specified balancing class, supports smooth coupling to small timing pulleys or precision gearheads.
