Product Description:

The MDD025B-N-100-N2G-040GA1 is a synchronous motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts commanded current into fast, controlled rotation for positioning, metering, and light spindle duties in compact automation equipment. The motor combines a high-speed rotor, integrated feedback, and an internal holding brake so the axis can accelerate quickly, report shaft position continuously, and remain in place when supply power is removed. This arrangement supports repeatable motion on small axes without adding separate external locking hardware.

At stall, the motor delivers 0.60 Nm of continuous torque, which is the amount it can provide continuously while the shaft is stopped. During normal operation, it reaches a nominal speed of 10000 rpm, which suits short-cycle motion and light spindle tasks. The integrated holding brake provides 1.0 Nm of braking torque to keep the axis in position after power is removed. A centering diameter of 40 mm helps align the flange with the machine interface, and power and feedback cables exit through connector on side A to simplify routing in tight enclosures. The standard housing and fitted shaft seal help limit the entry of dust or coolant at the rotating joint.

The motor uses size code 025 with a B-length housing, giving a compact body with enough thermal mass for steady operation. Rotor balancing is standard, which helps reduce vibration during high-speed operation. Position feedback is provided by resolver feedback, which supplies analog angle signals that remain reliable near power electronics. The drive end uses a plain shaft, and there is no shaft end on side B, leaving more clearance at the rear of the motor. This layout suits couplings to small pulleys or collets and keeps the package compact for miniature axes.
