Product Description:

The MDD025B-N-100-N2K-040MC0 is a small-frame synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, it converts commanded current into precise rotary motion for indexing tables, miniature gantries, and spindle-orientation modules in automated equipment. Its primary role is to deliver repeatable motion so closed-loop sequences remain accurate under varying mechanical loads. The compact motor format also suits installations where axis space is limited and low moving mass helps support quick response.

At standstill, the rotor delivers 0.60 Nm of continuous torque for static holding or slow traverse duties. During operation, it reaches a nominal speed of 10000 rpm, supporting rapid pick-and-place strokes and high-speed spindle tasks. Alignment to the machine frame is maintained by a 40 mm centering diameter that helps keep the transmission interface concentric. Electrical and feedback conductors exit on side A, reducing bend-radius demands when the unit sits against a mounting plate. A connecting cable with a coupling unit allows the harness to disconnect without disturbing cabinet-side terminations, which helps simplify service access around the motor.

Rotor position is measured through resolver feedback, eliminating the need for external incremental sensors. The motor ships without a blocking brake, so any vertical or holding axis must rely on drive torque or external clamps during power loss. The shaft is supplied without a shaft seal, so applications should avoid direct fluid exposure or use external sealing at the machine interface. A single-ended shaft with a keyway transfers torque to standard couplings. This arrangement is well suited to lightweight, high-velocity axes installed in clean and enclosed machine areas.
