Product Description:

The MDD025B-N-100-N2K-040MR1 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into controlled mechanical motion for compact automation axes. The device uses a 025 frame with a standard housing, carries standard rotor balancing, and fits into mounting fixtures through a 40 mm centering pilot. Its compact format suits small servo axes where low moving mass and accurate response are important. With its integrated feedback system, the motor supplies precise position data to the controller, supporting high-speed pick-and-place or indexing applications that demand repeatable accuracy.

The motor delivers a nominal speed of 10000 rpm, enabling rapid cycle times wherever high angular velocity is required. At standstill, it produces 0.60 Nm of continuous torque, which is appropriate for small carriers that hold loads while stationary. Installation is aided by the 40 mm centering diameter, which aligns the flange with adjoining machinery. A blocking brake is fitted, and its holding torque reaches 1.0 Nm, helping prevent drift when power is removed. The motor has a frame size of 025, and length code B keeps the overall package short so it can fit close to driven parts without reworking adjacent panels or guides.

Cabling exits on the right side through a shielded connector, simplifying wiring in cabinets where space on the opposite face is limited. The side-mounted connection can also reduce cable crowding near adjacent machine members. For motion feedback, the sensing method is resolver feedback, which supplies analog sine and cosine signals to the control system. Mechanical power leaves the unit through a keyway shaft, and no side B shaft is provided. A shaft seal is omitted, so the motor is better suited to clean installation areas where contamination does not exceed the open-end limits of the standard housing.
