MDD025C-N-100-N2G-040PB0
The MDD025C-N-100-N2G-040PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers where compact dimensions and high rotational speed are required for precise positioning tasks in assembly systems, semiconductor tools, and light pick-and-place axes. Its compact form helps it fit machine layouts where installation space is limited, especially on small axes that must move quickly and stop accurately.
This model delivers a continuous standstill torque of 0.90 Nm, giving small actuators enough holding force for static loads while minimizing heat rise in tight enclosures. Its maximum speed reaches 10000 rpm, which allows lower gear ratios or direct coupling to fast-moving shafts. A centering diameter of 40 mm aligns the frame with mounting plates and supports repeatable concentricity during installation. Power and feedback leads exit on side B, a layout that can simplify cable routing when the rear of the motor faces the cabinet wall. Quick-disconnect installation is supported through a single connector, which reduces the time needed to remove or reconnect the motor. Commutation and position data are supplied by resolver feedback, which tolerates electrical noise and temperature drift better than many incremental encoder arrangements in high-speed environments.
The mechanical interface uses a keyway shaft to limit slippage during rapid acceleration and deceleration. The front bearing region is protected by a shaft seal, which helps keep airborne coolant or lubricant from migrating into the winding cavity. The motor is supplied without a blocking brake, so any load-holding function must be provided externally when the axis is stopped. This arrangement can be suitable where regenerative braking or vertical load retention is handled by other machine components. The C-length housing keeps the motor short, which helps when it is mounted near slides, guards, or other closely spaced machine parts.
