MDD025B-N-100-N2G-040FD1
The MDD025B-N-100-N2G-040FD1 is a synchronous motor in the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a compact size-025, length-code B unit intended for use with digital drive controllers in fast-cycle automation tasks. In this role, the motor converts commanded electrical current into controlled rotary motion for positioning and speed-regulated applications. A standard housing and standard dynamic balancing support installation in general-purpose assemblies. Integrated feedback allows closed-loop position and velocity control in multi-axis machines where repeatable motion is required.
This model reaches a nominal speed of 10000 rpm, allowing high spindle or indexing rates when paired with compatible inverters. At standstill, it can supply 0.60 Nm of continuous torque, which is the steady load it can hold without overheating. For emergency stops or vertical axes, an integrated blocking brake delivers 1.0 Nm of retaining torque after power is removed. This helps prevent unintended movement when the axis is not energized. Rotor alignment during installation is simplified by a centering diameter of 40 mm, and the shaft position is reported through resolver feedback for real-time regulation.
Cabling exits on the rear face because the connection direction is Side B. The motor is supplied with a connecting cable with a coupling unit, so power and feedback lines can be connected through a matched interface. Motion is transmitted by a plain shaft, and the motor is built without a shaft seal, so the mounting location should be free of fluid spray. The single-ended shaft arrangement omits a side-B extension, which helps conserve space in compact servo packs. This layout is suitable for compact pick-and-place modules, laboratory automation equipment, and small winding systems.
