Product Description:

The MDD112B-N-020-N2M-130GL0 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies torque to axes that require closed-loop precision in industrial automation cells. The model couples directly to a drive amplifier, allowing position and velocity control through internal sensors, and its design supports mounting in machinery where compact dimensions and standard housing sizes are useful for positioning and coordinated motion.

Mechanical output starts with a continuous standstill torque of 17.5 Nm, which indicates the available holding torque at zero speed without additional gearing. Under rated excitation, the rotor reaches a nominal speed of 2000 rpm, so linear motion calculations can use a predictable baseline velocity. Accurate centering during coupling is aided by the 130 mm centering diameter, while standard balancing and a standard housing help minimize vibration in common frame mounts. The motor has frame length B and frame size 112, which correspond to the stack length and flange pattern used in this product line. A plain shaft transmits torque directly, and a shaft seal helps prevent lubricant egress when the unit is installed in oil-splashed areas.

Electrical interfaces leave the housing on the left side through a single connector that carries both power and feedback, which can simplify cable routing in tight cabinets. Position data comes from an integrated multi-turn absolute encoder, and velocity loops inside the drive use digital servo feedback (DSF) for high-resolution commutation. Because the motor is supplied without a blocking brake, external clamping is required when the axis must remain secure at power-off. The standard shaft end is supplied without a side-B extension, reducing overhung mass on the non-drive side. The connection type is a keyed circular connector.
