MDD025C-N-100-N2K-040GF0
The MDD025C-N-100-N2K-040GF0 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built for digital drive controllers, it converts electrical command signals into high-speed rotary motion for positioning axes, pick-and-place heads, and electronic component handlers in industrial automation. Its 025 frame size and standard housing help keep mass low in tight work envelopes while protecting the internal windings and sensors from airborne contaminants. This layout suits compact handling systems where fast acceleration and accurate position control are required. The compact housing also helps preserve clearance around slides, feeders, and cable carriers in densely packed machine sections.
The motor has a nominal speed of 10,000 rpm and a continuous standstill torque of 0.90 Nm, which suits rapid indexing with light fixtures. A pilot fit diameter of 40 mm centers the stator accurately on machine plates and helps maintain concentricity during high-speed operation. Wiring exits on the right side, and a connecting cable with a coupling unit allows replacement without rewiring the motor. An integrated absolute encoder supplies startup position data, while resolver feedback tracks ongoing motion for the control loop. This combination supports both initial reference availability and continuous speed feedback during short, repetitive motion cycles.
The output uses a plain shaft and is present only on side A, which eases coupling alignment in confined assemblies and avoids an unused shaft extension on side B. The shaft is fitted with a shaft seal, which helps protect bearing grease and the encoder cavity during extended high-speed operation. Because the unit is delivered without a blocking brake, external holding devices must be used on vertical axes. A single shaft end also reduces interference with nearby guards and moving tooling when installation space is restricted. Standard balancing keeps residual vibration low at full speed, even when the motor is mounted on lightweight aluminum stage plates, and the longer C-length housing supports stable running in compact assemblies.
