Product Description:

The Bosch Rexroth Indramat MDD025B-N-100-N2K-040FD0 is a synchronous servo motor built for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated DC bus energy into precise, high-speed rotary motion for small pick-and-place stations, index tables, and electronics assembly lines. Its compact frame size and high nominal speed make it well suited for axes where rapid acceleration and repeatable cycle performance are important. This motor type is suited to applications that need fast changes in speed without taking up much installation space.

Its nominal output speed reaches 10,000 rpm, enabling short positioning intervals and reduced dwell time between operations. At standstill, the motor sustains a continuous torque of 0.60 Nm, which helps it hold light tool loads steadily. A 40 mm centering diameter aligns the stator housing with precision mounting collars, while power and feedback conductors exit on side B to keep cable routing clear of adjacent machine parts. Field wiring uses a connecting cable with coupling unit, which keeps the connection compact and easy to route. The drive transmits power through a plain shaft, so couplings or pulleys can be attached without keyway machining. Standard dynamic balancing keeps residual vibration low across the speed range.

High-resolution feedback is provided by an integrated absolute encoder, giving the controller direct knowledge of rotor position after every power cycle. For servo loops that use analog position sensing, a secondary channel supplies resolver feedback, which supports compatibility with older drive cards. Because the unit ships without a blocking brake, parked loads must be held by drive torque or an external clamp. That arrangement is common where the axis is already supported by a separate holding mechanism or does not need brake-assisted parking. With motor size 025 and length code B, the package remains compact. A plain shaft end is present on side A only, and the lack of a shaft seal supports low-friction operation in clean, closed machines.
