Product Description:

The MDD090B-N-020-N2L-130GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts command signals from the associated drive into precise rotary motion for automation axes that require closed-loop velocity and position regulation. This operating role makes it suitable for positioning systems that must respond accurately to changing commands during motion. It is intended for machines that need repeatable speed control and accurate position holding over repeated duty cycles. Its integrated blocking brake holds the load when power is removed, which is useful on vertical axes and other applications that need secure stopping.

The rotor uses standard balancing to reduce vibration, and the motor can deliver a continuous standstill torque of 7.2 Nm without exceeding thermal limits. Under rated excitation, the shaft reaches a nominal speed of 2000 rpm, giving the axis a stable operating point for positioning and feed tasks. When static holding is required, the brake provides up to 11.0 Nm of torque. A centering diameter of 130 mm helps align the motor on the machine flange for accurate mounting. Motion feedback is provided through digital servo feedback, allowing the connected controller to monitor rotor position and speed in closed-loop operation. The motor has a plain shaft with no side B extension, and length code B indicates the medium mechanical stack in the 090 frame.

Cabling exits on the left side, and the power and feedback lines terminate through a keyed connector that keeps the electrical interface compact at the housing. A shaft seal limits the entry of coolants and fine particles along the shaft interface, which helps protect the internal bearings during machine operation. Frame designation 090 identifies the stator diameter used for this motor size. The standard housing and cable exit arrangement suit indexing tables, gantry axes, and material-handling arms where protected shaft entry and straightforward cable routing are useful.
