MDD025B-N-100-N2G-040MB0
The MDD025B-N-100-N2G-040MB0 is a synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it supplies precise torque and velocity for light-duty axes, conveyors, and assembly fixtures in industrial automation. The compact 025 frame size with B length helps the motor fit installations where mounting space is limited, while still supporting accurate motion control in small machine assemblies.
The motor reaches a nominal speed of 10000 rpm, allowing high rotational performance in compact drive systems. Its continuous stall torque is 0.60 Nm, making it suitable for holding duty and low-speed feed tasks that require steady torque without overheating. A centering diameter of 40 mm helps align the motor accurately with the mating flange. Power and feedback conductors exit on side B, which can simplify cable routing in machines with rear cable access. The motor uses a sealed connector, so connections can be made without opening the housing. Standard dynamic balancing helps reduce vibration during high-speed operation, and the housing uses the standard enclosure style for this motor line.
The output shaft uses a keyway, so torque is transferred through a keyed hub rather than by clamping force alone. The motor is supplied with no blocking brake, so any holding function at standstill must be provided by the drive or by external mechanical means. It is also delivered without a shaft seal, so it is best suited for clean, dry installation areas. Rotor position is provided through resolver feedback, which gives the controller reliable position information with good resistance to electrical noise. The motor uses a single shaft end, and the absence of a second shaft extension on side B helps keep the overall length short.
