Product Description:

The MDD071A-N-060-N2S-095PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended to be paired with digital drive controllers where closed-loop torque and velocity control are necessary for automated machinery such as pick-and-place axes, indexing tables, or light machining spindles. By delivering rated mechanical power directly through its rotor, the unit converts electrical energy from the drive into controlled rotary motion that can be precisely coordinated with other axes in an industrial system.

The motor delivers a continuous standstill torque of 2.2 Nm, giving it the capability to hold loads without overheating while stationary. During operation it can reach a nominal speed of 6000 min⁻¹, supporting high-cycle tasks that demand fast positioning. A blocking brake is integrated and can apply up to 3.0 Nm of holding torque to secure vertical or suspended loads when power is removed. Mechanical centering for mounting is guided by a 95 mm centering diameter, ensuring alignment with gearbox or flange faces. Power and feedback conductors exit on Side B of the housing, simplifying cabinet routing when the motor faces the machine. Torque is transmitted through a shaft that is machined with a keyway; this form fit prevents slip between the motor and the coupled element under dynamic load.

Signal quality to the drive is maintained by the integrated Digital servo feedback (DSF) encoder, which returns absolute position data for precise commutation. The frame is designated size 071 and length code A, so the motor fits into tight spaces while matching the power density expected from this series. The motor is built with a shaft seal, which protects the internal bearings from lubricant loss and airborne contaminants, and the stator is balanced to the standard class to limit vibration in high-speed operation. The single-cable connector system and standard housing finish allow straightforward installation with minimal additional hardware.
