Product Description:

The MDD025A-N-100-N2K-040PC1 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into rapid, accurate rotation for compact tooling axes and pick-and-place heads. Its 025 frame and A-length housing shorten overall depth so the motor can mount inside crowded machine enclosures without altering cabinet layouts. This compact format suits motion systems that place the motor close to slides, grippers, or transfer mechanisms where installation space is limited. It is well suited to small servo axes that need quick starts, short travel cycles, and precise stopping without the mass of a larger frame.

During steady operation, the rotor delivers a continuous stall torque of 0.33 Nm, while the integrated blocking brake applies 1.0 Nm of static holding torque to secure vertical or suspended loads. The brake can hold the shaft at standstill when gravity or external force would otherwise move the load. High-speed tasks are supported by a nominal shaft velocity of 10,000 rpm. Standard rotor balancing limits vibration at this speed, and the centering pilot measures 40 mm to align the motor face with gearbox or flange hardware. Power and feedback conductors exit on side A, which keeps cable routing on one end of the motor. The keyed shaft end supports positive torque transmission, while the standard enclosure style keeps the overall layout consistent with common machine mounting arrangements.

Position data is generated by an embedded integrated absolute encoder, and the drive also receives resolver feedback for commutation, enabling tight control loops across the full speed range. Using both signal types helps the drive maintain stable motion during low-speed holding and rapid direction changes. A durable shaft seal guards the front bearing against coolant splash, and the motor uses a single shaft end with no extension on side B to save space. Cabling integrity is maintained by the connecting cable with coupling unit, which mates flush to the housing. The housing remains compact while accommodating the feedback connection and front-end sealing.
