Product Description:

The MDD025C-N-100-N2G-040MR0 is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for integration with digital drive controllers, the unit converts electrical commands into mechanical rotation for precise axis control in industrial automation. As a member of the compact 025 size range with length code C, it supports high-speed positioning while keeping installation space low. It can be used in compact handling, feeding, and positioning assemblies.

The motor reaches a nominal speed of 10,000 rpm, enabling rapid cycle execution where short positioning times are required. At standstill, it supplies 0.90 Nm of continuous torque, so the shaft can hold a steady load within the motor’s thermal capacity. Position and velocity loops are closed through resolver feedback, which provides analog sine-cosine signals to the drive for stable control even at elevated temperatures. Mechanical linkage is through a keyway shaft, giving positive torque transmission to pulleys or couplings. Alignment during mounting is aided by a 40 mm centering diameter, which helps keep the motor concentric with the machine frame.

Power and feedback plugs face the right side because the connection direction is fixed in that orientation. The connector terminals allow the cables to be detached without opening the housing, which helps keep installation and access straightforward. The motor uses a standard housing and standard balancing, so it can be mounted without added correction weights. It is supplied without a blocking brake, so the axis must be held at power-off by drive torque or an external clamp. The design does not include a shaft seal, and the shaft end is provided only on side A. This arrangement is suited to clean installations where sealing at the motor shaft is not required.
