MDD025B-N-100-N2G-040ME1
The MDD025B-N-100-N2G-040ME1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, allowing precise velocity and position control in automated assembly stations, compact indexing units, and small handling axes. This type of motor is suited to applications that need accurate closed-loop motion from a small housing. Its mechanical format uses the 025 frame with the B length code, and the standard single-ended shaft layout has no secondary side-B extension for direct coupling to small gearboxes or timing pulleys.
The rotor is balanced to Standard grade, which helps maintain smooth operation through the usable speed range. A centering pilot of 40 mm keeps the housing aligned on the mounting surface, and the output uses a keyway shaft for positive torque transfer to the driven element. At standstill, the motor can deliver a continuous torque of 0.60 Nm, making it suitable for static positioning and low-speed holding tasks within its thermal limits. With a matching controller, it reaches a nominal speed of 10000 rpm, and the fixed left-side cable exit helps simplify routing where installation space is limited. These operating traits support fast start-stop motion in compact automation equipment.
A blocking brake provides 1.0 Nm of holding torque to resist load back-drive when power is removed. Rotor position and speed are reported through resolver feedback, giving the drive robust feedback without relying on an optical encoder. Power and sensor conductors are combined in a connecting cable with coupling unit, which reduces the number of separate connection points in confined machine spaces. The design is supplied without a shaft seal, so it is best suited for clean, dry installation areas or for machines that provide sealing at the driven interface. That arrangement is useful where compact packaging matters more than integrated sealing at the motor shaft.
