Product Description:

The MDD115B-N-030-N2L-130PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into controlled rotary motion for machine tools, packaging equipment, and material-handling axes. The synchronous design supports accurate speed and position control during repeated starts, stops, and reversing cycles. Its compact form allows it to fit servo-driven assemblies where mounting space is limited but responsive motion is still required.

This unit uses a centering diameter of 130 mm for accurate alignment in precision mounting pilots. It uses the B motor length code, and the shaft, power leads, and feedback leads are arranged on Side A through a sealed Connector. Continuous stall torque reaches 38.0 Nm, which allows the axis to hold demanding inertial loads without overheating during low-speed operation. The rotor reaches a nominal speed of 3000 rpm, supporting fast motion profiles in positioning and transfer tasks. The standard balancing grade also helps the motor run smoothly in typical industrial servo installations.

A blocking brake with a static torque of 45.0 Nm locks the shaft when the drive is disabled, which is useful for axes that must remain in place after power is removed. Feedback is provided by integrated Digital servo feedback (DSF), giving the controller precise rotor position data for closed-loop regulation. The output shaft has a seal and a keyway so torque can be transferred securely to couplings or pulleys. The motor is size 115, and the non-drive end remains plain to avoid unnecessary overhung mass on the rear bearing. The sealed output end helps protect internal parts from contaminants that can enter along the shaft during routine machine operation.
