MDD025C-N-100-N2K-040GB1
The MDD025C-N-100-N2K-040GB1 synchronous motor is built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as a drive element for digital motion controllers, translating command currents into rapid rotation for light-duty axes in assembly stations and electronics handling equipment. This role makes it suitable for short-cycle positioning tasks and compact transfer mechanisms. Size 025 and the C length code keep the unit short, while the standard housing and balancing help minimize transmitted vibration. A plain shaft is provided on the drive end, and the opposite end is closed because this variant is supplied without a shaft on side B.
The motor mounts through a centering collar that measures 40 mm in diameter, which helps maintain accurate alignment with mounting plates. Continuous stall torque is 0.90 Nm, providing holding force for indexing tables without oversizing the drive. The windings permit a maximum operating speed of 10000 rpm, allowing high throughput when paired with suitable gearing. Cables are routed rearward because the power and feedback connectors sit on the side B face and use a sealed connector interface. Position information comes from an integrated absolute encoder, so the controller knows rotor angle after startup without a homing cycle.
The motor also includes a blocking brake that delivers 1.0 Nm of static torque to hold the shaft when power is removed. Its internal feedback system supports closed-loop motion control across the operating speed range, and the brake helps keep the axis in place during power-off pauses. An internal shaft seal keeps lubricant inside the bearing chamber and helps prevent coolant spray from entering. The compact frame coded 025 fits densely packed multi-axis assemblies where rear cable routing and secure shaft holding are required.
