Product Description:

The MDD025C-N-100-N2K-040PA1 is a synchronous motor produced by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. It serves as a compact drive element in industrial automation where rapid positioning and regulated speed are required. A blocking brake, resolver feedback, and an integrated absolute encoder are incorporated so the motor can start, stop, and report position without external sensing devices. This arrangement reduces external wiring and helps the drive maintain stable position control during short indexing movements.

This model reaches a nominal speed of 10,000 rpm, enabling fast cycles for lightweight loads. Continuous torque at standstill is rated at 0.90 Nm, which indicates the sustained torque the stator can generate while the rotor remains locked. The centering diameter of 40 mm aligns the housing with machine frames for concentric mounting. A plug-in connector carries power and feedback, and all conductors exit on side A so cable routing remains concentrated on one face of the motor. Rotor orientation data is returned through resolver feedback, providing analog angle information that tolerates electrical noise well. Standard balancing helps limit residual vibration and supports smooth operation at elevated speeds.

The holding system supplies 1.0 Nm of static brake torque, preventing motion whenever the controller removes drive current. Mechanical coupling is handled by a keyway shaft, and a factory-installed shaft seal helps keep contaminants away from the bearings. Length designation C and frame size 025 indicate a short stack with low inertia, which suits applications that require frequent reversals and quick response. Additional traits include a standard aluminum housing, a single shaft end on side A, and an absolute encoder reference associated with the resolver system. The brake is intended to hold a stopped axis, while the housing supports heat dissipation during normal operation.
