Product Description:

The MDD025A-N-100-N2K-040PR0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the unit converts commanded current into high-speed rotary motion for light-duty positioning stages, spindles, and indexing equipment in automated production lines. A standard housing with motor size 025 and length code A gives the assembly a small footprint that simplifies integration on narrow machine plates and in densely packed equipment. This layout is useful where short travel moves, frequent starts and stops, and limited installation space are common.

A centering diameter of 40 mm guides the motor into a flange bore so the shaft runs true to adjacent transmission elements. Continuous torque at standstill reaches 0.33 Nm, allowing the rotor to hold light loads while current remains within rated limits. During operation, the shaft can spin at up to 10,000 rpm, which suits machinery that requires short move times and quick speed changes. Power and feedback conductors exit on the right side, and the motor uses a removable connector style plug that simplifies cable routing and connection. Standard dynamic balancing helps keep vibration low during extended operation.

Position information is delivered by an integrated absolute encoder, while resolver feedback supports rotor angle calculation during rapid acceleration. Because the unit ships without a blocking brake, static holding force must be supplied by the drive or by an external clamp when power is removed. A factory-installed shaft seal protects the interior against coolant or dust ingress, and the single-ended keyway shaft simplifies coupling to pulleys or gears. The motor has a shaft end on side A and no shaft extension on side B, which helps preserve space around nearby components and leaves the rear of the housing clear for cable routing.
