Product Description:

The MDD025B-N-100-N2G-040MB0 is a miniature AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts commanded current into precisely controlled rotary motion for feeders, small handling arms, and other fast-cycling automation axes. Its compact frame and low-inertia rotor help conserve mechanical space in compact machines, electronic assembly platforms, and test fixtures. The motor is suited to applications that need quick acceleration, repeatable positioning, and stable speed control in a small installation envelope.

At its rated operating point, the rotor can spin at 10000 rpm, giving the axis enough surface speed for indexing duties that demand short cycle times. The continuous standstill torque of 0.60 Nm shows how much load the motor can hold without overheating while it is energized and motionless. A centering diameter of 40 mm forms the locating register on the mounting face, helping maintain coaxial alignment with gearheads or machine frames. Power and feedback leads exit on side B, so cable loops can be routed away from adjacent tooling and moving machine parts. A single-plug connector keeps the electrical interface compact and maintains sealing integrity. Position and velocity are tracked by resolver feedback, supplying rotor angle information to the drive for commutation and closed-loop regulation.

The motor is supplied without a blocking brake, so external drive control or machine mechanics must provide holding force where required. Its standard housing and balancing grade support smooth running while keeping the assembly compact. The motor size 025 envelope suits linear slides and other installations with limited clearance. Motor length code B, a keyway shaft, the absence of a shaft seal, and the standard single-ended shaft arrangement support straightforward coupling in protected indoor installations.
