MDD025B-N-100-N2G-040MD0
The MDD025B-N-100-N2G-040MD0 is a compact synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical command signals into controlled mechanical rotation for positioning and velocity tasks on pick-and-place axes, small conveyors, and indexing tables used throughout industrial automation. The motor is intended for applications that require accurate starts, stops, and speed changes during repeated cycles. This helps the connected drive maintain smooth motion on small automated axes that need repeatable performance. Its compact size also suits machine sections where installation space is limited.
The motor offers a continuous torque at standstill of 0.60 Nm, meaning it can deliver this torque continuously without overheating while motionless. Its nominal speed is 10000 rpm, which suits fast-cycling machinery that depends on high rotor speed. A centering diameter of 40 mm aligns the front flange with machine mounts to maintain concentricity at high speed. Electrical power and feedback conductors exit on side B, and they terminate in a connecting cable with coupling unit for a direct plug-in connection. The 025 frame size and B length keep the overall package short for compact mechanical layouts.
The rotor uses standard balancing to limit vibration and reduce bearing load during continuous duty. Rotor position is returned to the drive by resolver feedback, allowing closed-loop control across the operating speed range. The motor is supplied without a blocking brake, so holding position when power is removed requires drive torque or an external clamp. Its shaft uses a keyway to provide secure torque transfer into couplings or pulleys during acceleration and deceleration. That shaft form is commonly used where positive mechanical engagement is preferred over friction-only clamping.
