MDD025B-N-100-N2G-040PB1
The MDD025B-N-100-N2G-040PB1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is integrated into servo loops where precise velocity and position regulation are required. It is suited for light-duty axes, pick-and-place heads, and electronic assembly stages in industrial automation where compact size and repeatable motion are important.
The mechanical interface uses a centering diameter of 40 mm, which sets the concentric fit between the housing and the machine frame. Connections exit on side B, so the power and feedback plugs point away from the drive end and simplify cable routing inside cramped enclosures. A single multi-pin connector carries phase power and signal lines, reducing separate wiring runs and helping keep the installation compact. The motor delivers a continuous stall torque of 0.60 Nm and reaches a nominal speed of 10,000 rpm for rapid indexing tasks. The unit uses standard dynamic balancing and a standard cast housing, which keep vibration low without adding extra mass that would slow acceleration. Size code 025 and length code B set the overall envelope used when selecting gearheads or mechanical adapters in tightly spaced assemblies.
A blocking brake is factory-installed, supplying 1.0 Nm of static holding torque to keep vertical or back-driven loads stationary when the drive is disabled. Rotor position is reported through resolver feedback, providing angle information for servo control and stable operation across typical industrial motion profiles. The shaft is machined with a keyway to transmit torque through keyed couplings, and it is built with a shaft seal to limit lubricant migration into the motor during operation. The shaft end follows the standard single-ended design without an auxiliary output on the opposite side.
