MDD025A-N-100-N2G-040GD0
The MDD025A-N-100-N2G-040GD0 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Intended for digital drive controllers in industrial automation, it delivers controlled rotary motion for light-duty axes such as small pick-and-place heads, feeders, or metering pumps. Size 025 and length code A keep the housing short, which helps the motor fit into compact machine sections where installation space is limited. A standard housing and standard dynamic balancing also help reduce vibration transfer to nearby machine elements during operation.
The electrical design supports a nominal speed of 10000 rpm, allowing rapid positioning cycles when paired with high-frequency inverters. Continuous stall torque is rated at 0.33 Nm, which is the torque the motor can hold continuously without exceeding thermal limits. Rotor position is reported through resolver feedback, providing analog sine-cosine signals that remain reliable at high temperatures and during fast acceleration. All power and signal conductors exit on side B of the frame, and the factory-installed connecting cable with coupling unit simplifies routing inside moving cable tracks. This layout supports accurate closed-loop control and keeps the connection path compact.
A centering shoulder of 40 mm aligns the flange with gearbox or fixture bores for accurate installation. The output uses a plain shaft, which mates with standard collets or press-fit couplings. The motor is supplied without a blocking brake, so any static holding force must be provided by the drive or by an external brake module. A factory-installed shaft seal limits the ingress of coolant or fine dust at the output end. The shaft end on side B is omitted, which reduces overall length and avoids unintended overhung loads.
