Product Description:

The MDD090C-N-030-N2L-130GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it provides closed-loop rotary motion for coordinated axes in automated lines, packaging equipment, and material-handling stations. Feedback electronics are integrated into the motor, so commanded current is converted into controlled torque and speed while actual rotor position is returned to the drive. This arrangement supports accurate positioning, stable speed regulation, and repeatable motion during indexing, transfer, and synchronized machine cycles. Because the feedback system is built in, the motor remains compact and does not require a separate external feedback assembly.

The mechanical interface includes a centering pilot of 130 mm, which helps align the motor housing with gearboxes or adapter plates and keeps the mounting face positioned accurately. Continuous torque at standstill is 10.4 Nm, so the motor can hold that load continuously at zero speed without exceeding its thermal capability. The winding supports a nominal speed of 3000 rpm, allowing short cycle times when the motor is paired with a suitable inverter. All power and signal conductors leave through a right-side connector orientation, and position data is supplied through Digital servo feedback (DSF) for closed-loop speed and position control.

The motor uses frame size 090 with length code C, which gives a deeper active stack while retaining the square outline of the housing. The motor has a shaft seal, which helps keep coolant or oil from migrating along the plain shaft interface. The unit is supplied without a blocking brake, so holding torque at standstill must come from the drive or from an external locking device. The shaft remains single-ended without a side-B extension, which leaves the rear of the motor free for the connector area. A plain shaft interface allows torque transfer through standard hubs or clamping couplings.
