Product Description:

The MDD025B-N-100-N2G-040PR0 is a brushless synchronous motor built by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. Intended for compact positioning axes, it converts command currents from the controller into mechanical rotation that can be coupled directly to precision gear stages or belt transmissions on automated machinery. Its compact format suits small servo axes where limited installation space and responsive motion are required.

The motor delivers a continuous standstill torque of 0.60 Nm, allowing light load holding without thermal overload, while its rated speed reaches 10000 rpm so high-throughput indexing is possible. A centering flange diameter of 40 mm provides a locating fit on mounting plates and helps maintain repeatable alignment. Rotor position is reported through resolver feedback, which supplies absolute angle data that resists electrical noise. Power and feedback conductors exit on the right side, which helps cable routing in narrow enclosures. Standard dynamic balancing limits vibration during rapid acceleration, and the connector interface supports a secure cable connection.

A plug-in connector with coded pins simplifies wiring to the drive. The shaft has a standard shaft end without an extension on side B, which helps save space in tandem motor arrangements. Protection against lubricant migration is provided with a shaft seal, and drive torque is transmitted through a keyway machined into the shaft. The motor housing uses the series' standard cooling surface profile. Because the motor does not include a blocking brake, vertical loads must be secured by external clamping or drive torque. Size code 025 and length code B keep overall mass low, and the product retains IP65 protection when mated to shielded connectors.
