MDD025B-N-100-N2K-040MA1
The Bosch Rexroth Indramat MDD025B-N-100-N2K-040MA1 belongs to the MDD Synchronous Motors series and serves as a compact servo motor for digital drive controllers in industrial automation. It converts electrical power into precisely regulated mechanical motion, allowing machine tools, pick-and-place modules, and other fast-cycle axes to reach commanded speeds and torques under closed-loop control during repeated duty cycles. Rotor-mounted permanent magnets and integrated feedback support rapid response and high positioning accuracy while keeping the motor compact for tight machine layouts.
At its rated operating point, the motor sustains a shaft speed of 10000 min⁻¹. During standstill, it can deliver a continuous torque of 0.60 Nm, so heat rise remains within the limits of the B-length stator and standard housing. A blocking brake integrated at the non-drive end supplies up to 1.0 Nm of static holding torque, allowing vertical axes to maintain position when power is removed. Mechanical balancing is standard, and the rotor seats against a centering pilot of 40 mm for concentric alignment. Cabling is simplified because the power and feedback plugs face Side A and are grouped in a single connector. The motor follows size code 025 and length code B, so its footprint matches other MDD units with the same frame.
Position and velocity data are supplied by an integrated absolute encoder for precise axis control. The motor uses the drive’s resolver feedback interface for closed-loop commutation without external sensors. The single-ended keyway shaft engages couplings directly, and the standard design uses only one drive-side shaft end, leaving no protrusion on the opposite face. The motor is supplied without a shaft seal, so installations exposed to coolant or oil must provide external sealing at the machine interface.
