Product Description:
The MDD090B-N-020-N2L-130GR1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and provides controlled rotary motion for feed axes, transfer units, and other automated machine movements. The standard housing encloses the stator, and the rotor is balanced to the standard grade so vibration remains suitable for normal servo operation. The motor uses a single plain shaft with no second shaft end, which suits inline couplings where available installation space is limited. This layout works well in automated transfer lines and material-handling stations.
The motor has a continuous standstill torque of 7.2 Nm, which is the load it can hold at zero speed without overheating under rated conditions. During operation, it can reach a nominal speed of 2000 rpm. A blocking brake is included, and its holding torque is rated at 6.5 Nm to help keep a vertical or suspended axis in place after power is removed. Position information is provided through digital servo feedback for accurate speed and angle control inside the drive loop. A 130 mm centering diameter helps align the motor on the machine interface, and electrical connections are made through a connector.
All power leads exit on the right side, which can simplify routing when adjacent equipment limits cable space. The motor has frame size 090, placing it in the mid-range envelope used for many servo-driven machine axes. A shaft seal protects the output interface from coolant splash and airborne oil. The standard housing and normal balance grade remain in place, so no special mechanical variation is indicated in the listed configuration. This arrangement is suitable for enclosed automation equipment where cable direction and sealing are important during installation.
