Product Description:

The MDD025B-N-100-N2G-040FE0 is a synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded electrical input into controlled rotary motion for lightweight pick-and-place axes, indexing tables, and miniature actuators in automated assembly equipment. The motor combines a resolver sensor with a low-inertia rotor so the drive can regulate speed and position in real time during repetitive, high-cycle motion. Its compact format also suits short-travel mechanisms where low moving mass helps support quick acceleration and reversal. This makes it a practical choice for compact automation stations that perform frequent starts, stops, and short indexing moves throughout a production cycle.

During continuous stall operation, the rotor delivers 0.60 Nm of torque, and it can reach a nominal speed of 10000 rpm for rapid duty cycles. Accurate mechanical alignment is supported by a 40 mm centering diameter, while a plain shaft provides a smooth mounting surface for collets or micro-belts. Position feedback is provided through resolver feedback, allowing the connected drive to monitor rotor position and speed during closed-loop operation. The housing uses a standard aluminum body, and the motor is size 025 with length code B. It is supplied without a shaft seal or a secondary shaft end, which helps keep mass and bearing friction low.

Rotor vibration is managed with standard balancing. Electrical power and feedback are routed through a connecting cable with a coupling unit, and all connectors are arranged on the left side to suit machines whose cable trays run to the right of the motor. The motor is supplied without a blocking brake, so holding torque during shutdown must be provided externally when the application requires it. The connection arrangement also helps when clearance around the rear of the motor is limited.
