MDD025B-N-100-N2G-040MC1
The MDD025B-N-100-N2G-040MC1 is a brushless servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts electrical commands into rapid rotary motion for compact automation axes such as pick-and-place heads, labeling modules, and auxiliary spindles. Its 025 frame size, B length code, and standard housing suit installations where mounting space is limited but fast response is still required. This combination makes the motor appropriate for small machine sections that need accurate motion without adding unnecessary bulk.
At a continuous standstill torque of 0.60 Nm, the rotor can support moderate loads without exceeding allowable winding temperature. When acceleration is required, the motor reaches a nominal speed of 10000 rpm, which helps shorten indexing cycles and supports fast repetitive motion. A spring-applied brake provides 1.0 Nm of static holding torque, so the shaft can remain secured when power is removed. Position information is returned through resolver feedback, allowing stable closed-loop control in environments where electrical noise may be present. The flange includes a centering pilot of 40 mm, and the power and feedback conductors exit toward side A for straightforward cable routing in compact cabinets.
The rotor and flange use Standard balancing quality to help limit vibration during high-speed operation. A factory-fitted connecting cable with a coupling unit removes the need for a separate terminal box and keeps the electrical connection compact. The output is a single-ended keyway shaft, which allows direct torque transfer to small pulleys or gear stages. Because the motor is supplied without a shaft seal, it is best suited for clean, dry enclosures where dirt and fluid exposure are controlled. The standard housing and the lack of a side B shaft extension keep the overall motor length short, which is useful when several axes must fit close together in a multi-axis machine layout.
