Product Description:

The MDD090B-N-020-N2L-110PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for digital drive controllers, it converts commanded current into precise rotary motion for positioning, indexing, and moderate-speed transport tasks in automated equipment. Its standard housing and connector-based wiring simplify installation inside machine frames and help conserve mounting space. The motor is suited to applications that need repeatable motion without adding separate feedback hardware at the axis.

The motor produces a continuous standstill torque of 7.2 Nm, allowing holding loads in place or maintaining tension without overheating. Under operation it reaches a nominal speed of 2000 rpm, which matches common ball-screw drives, belt axes, and transfer mechanisms. A built-in brake provides 11.0 Nm of holding torque when power is removed, helping prevent backdriving on vertical or load-biased axes. Accurate alignment with couplings or gearheads is supported by a 110 mm pilot diameter, and all power and feedback leads exit on Side B through a sealed circular connector. This cable routing keeps the opposite face clear for mechanical integration.

The motor uses size 090 with length code B, giving it a mid-frame housing that fits many handling and gantry systems. Rotor position is reported through digital servo feedback, allowing the controller to maintain closed-loop speed and position accuracy during acceleration and load changes. A spring-applied blocking brake secures the shaft during stops, and the output shaft uses a keyway for positive torque transmission to pulleys, couplings, or geared attachments. The shaft is also fitted with a seal to help keep contaminants away from internal bearing surfaces while retaining lubricant at the drive end.
