MDD025B-N-100-N2K-040FA1
The MDD025B-N-100-N2K-040FA1 is a synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for digital drive controllers, it supplies rapid rotary motion to automated pick-and-place stages, labeling heads, and similar compact axes in industrial plants. The unit’s electromagnetic design supports high commanded speeds, and the integrated position transducer allows the drive to close its control loop without external sensors. This arrangement helps keep the motor assembly compact on small machine axes where installation space is limited.
At standstill, the rotor can deliver a continuous torque of 0.60 Nm, which is the load it can hold indefinitely without overheating. During motion, it reaches a nominal speed of 10000 rpm, which helps reduce the need for large gear ratios in fast-moving axes. Position reporting is handled by an integrated absolute encoder, and its multi-turn data removes the need for homing after power-up. A centering diameter of 40 mm aligns the flange accurately on the mounting surface and helps limit radial runout. To secure the shaft when power is lost, the motor includes a blocking brake that provides 1.0 Nm of holding torque, allowing vertical loads to remain stationary without external locks.
Mechanical integration is aided by electrical interfaces placed on Side A, where a keyed connector carries both power and feedback conductors. Cable routing stays straightforward because the connection exits from one side of the housing. The frame uses standard balancing and a standard housing to support smooth rotation with low vibration. Length code B and size code 025 give the motor a slender body that fits tight machine envelopes. The plain shaft is delivered without a shaft seal, and the design omits a secondary shaft end so couplings are installed only on the drive side.
