MDD025B-N-100-N2G-040ML1
The MDD025B-N-100-N2G-040ML1 is a compact servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts commanded current into rotary motion for positioning tasks in automated machinery. Its 025 frame and B length give the motor a small footprint that suits light moving masses, and the compact housing helps it fit installations where mounting space is limited. This makes it suitable for pick-and-place units, feed systems, and other compact axes that demand responsive motion. The motor is intended for precise, repeatable movement rather than heavy continuous-duty conveying.
The rotor can reach a peak operating speed of 10000 rpm, which supports high-speed motion on small axes. Under standstill conditions, the stator winding produces a continuous torque of 0.60 Nm, allowing stable holding and low-speed indexing without excessive heat buildup. For stopping and holding at rest, the integrated blocking brake provides 1.0 Nm of static torque when power is removed. Position data is returned through resolver feedback, which supplies rotor angle signals across the speed range. All power and feedback cabling exits on the left side of the housing, which can simplify cable routing in tight machine layouts. The mounting interface includes a centering diameter of 40 mm for accurate alignment with connected mechanics.
Electrical connections use a compact connector that keeps the housing easy to disconnect and helps preserve the motor's slim profile. Torque is transmitted through a keyway, which provides a secure mechanical connection to couplings during repeated start-stop operation. The motor is supplied without a shaft seal, making it better suited to clean installations or machines that use external sealing at the driven side. It can be paired with external coupling and sealing methods chosen for the machine layout. This arrangement reduces added friction at the shaft and supports smooth rotation across the normal operating range.
