Product Description:
The MDD090B-N-020-N2L-110PR2 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is intended for use with digital drive controllers and delivers controlled rotary motion in automated machinery where axis response and positioning consistency are important. This makes it suitable for feed axes, transfer units, and other servo-driven machine sections in packaging and handling systems. The motor uses a 090 frame with a B-length housing and a single shaft end, so torque is transmitted only from the drive side. A blocking brake is integrated for holding at standstill, and the power and feedback leads are routed through a right-hand connector interface.
The motor reaches a nominal speed of 2000 rpm, allowing moderately fast axis cycles in material-handling and packaging equipment. At standstill, it can supply 7.2 Nm continuously for static positioning duties without exceeding its thermal limit. The blocking brake provides 11.0 Nm of holding torque when the axis must remain fixed after power is removed. Position data is returned through digital servo feedback (DSF), which lets the controller regulate speed and position in a closed loop during changing load conditions. Cables exit on the right side of the stator housing, which can simplify routing in machines where the drive and cable path are arranged on that side.
A centering diameter of 110 mm fits standard Rexroth motor mounts and helps maintain shaft alignment during installation on machine flanges and gear inputs. The motor is supplied with a shaft seal, which helps keep oil mist, dust, and coolant away from the bearing area during operation. The output uses a keyway for positive mechanical coupling to pulleys, pinions, or gear hubs that must transmit torque without slip. Dynamic balance is rated as standard for operation at the listed speed, supporting smooth running in typical industrial service. The overall mechanical arrangement is suitable for general machine-duty applications that use a keyed shaft and flange-mounted motor installation.
