Product Description:

The MDD025B-N-100-N2G-040GD1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts electrical commands from the drive into quick rotary motion for positioning tasks in industrial automation. Its B-length housing, size 025 frame, and integrated blocking brake support use on light material-handling axes that still require accurate stopping and holding. This type of motor is commonly used where rapid acceleration, repeatable positioning, and compact mounting dimensions are needed on the same axis. The compact layout also suits installations where motor length must be kept low behind the mounting surface.

It includes standard rotor balancing to minimize vibration at its nominal speed of 10000 rpm. During standstill, the stator can deliver a continuous torque of 0.60 Nm, which suits indexing tables that dwell under load without overheating. A centering diameter of 40 mm fits mounting bosses and helps keep alignment precise. All electrical terminations exit on side B, which can simplify cable routing in tight cabinets. Position information is returned through resolver feedback, so the controller receives shaft position signals for closed-loop control.

An integrated blocking brake provides up to 1.0 Nm of holding torque, allowing vertical axes to remain fixed when power is removed. The power leads are supplied through a connecting cable with coupling unit, which allows quick disconnection without disturbing the seals. The motor uses a plain shaft, making it suitable for friction-fit couplings rather than keyed hubs, and it is built with a shaft seal to help protect the front bearing from splash ingress. There is no shaft end on the rear side, and the enclosure maintains IP65 protection for compact servo installations. This arrangement helps keep the front end protected during routine machine operation.
