Product Description:

The MDD090B-N-020-N2M-110GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, the unit converts commanded current into accurate rotary motion for machine tools, handling robots, and packaging stations. Its standard housing and standard balancing support straightforward mounting, and the built-in blocking brake helps hold the axis whenever system power is removed. This combination suits equipment that needs precise motion during operation and secure load holding during stops.

Its nominal speed is 2000 rpm, which gives the drive a steady operating point for velocity control without exceeding thermal limits. At standstill, the motor supplies 7.2 Nm of continuous torque, while the integrated brake provides a static holding torque of 6.5 Nm when the inverter is disabled. Position and revolution tracking are handled by an integrated multi-turn absolute encoder, so stored turn information allows the axis to return to operation immediately after power is restored. All power and feedback plugs face side A, which keeps the connections grouped at one end of the housing and helps maintain a cleaner cable route along a single machine wall.

A concentric pilot of 110 mm centers the flange for repeatable alignment with gearboxes or couplings and helps reduce radial runout at the mounting interface. Digital servo feedback (DSF) improves control accuracy because its high-resolution incremental channel gives the drive fast velocity updates during motion. The rotor uses a plain shaft, allowing clamp hubs, timing pulleys, or friction couplings to be installed without keyway machining. A fitted shaft seal helps block lubricant or coolant migration along the shaft journal, and a sealed mating surface supports IP65-class protection at the machine interface.
