Product Description:

The MDD090B-N-030-N2M-130PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Engineered for digital drive controllers, it converts electrical energy into precisely regulated rotation for automated tooling, conveyors, and positioning modules. The unit is supplied with standard rotor balancing and a standard housing. Its single-ended shaft without a side-B extension fits drive trains that accept a keyed connection while keeping overall motor length compact in installations with limited rear clearance. This motor format is suited to machines that require accurate speed control and repeatable positioning over frequent duty cycles.

Its continuous torque at standstill reaches 7.2 Nm, allowing the axis to hold static loads without additional gearing. During operation, the rotor can attain a nominal velocity of 3000 rpm, matching inverter outputs commonly used in high-speed machining or pick-and-place routines. A centering shoulder of 130 mm aligns the flange to machine frames so radial runout remains low during coupling. All power, brake, and encoder leads exit on side A, keeping connectors clear of coolant spray when the motor is mounted in a horizontal orientation. The sealed connector system accommodates prefabricated hybrid cables and supports consistent electromagnetic shielding along the cable path. This cable direction can also reduce bend stress where space is limited near guards or adjacent machine elements.

The motor includes a blocking brake that supplies 6.5 Nm of torque for secure holding when power is removed. Position verification is generated internally by an integrated multiturn absolute encoder, and the resulting signals are transmitted as digital servo feedback (DSF) to the drive. This arrangement allows the controller to retain position information across multiple revolutions after a power cycle. The shaft uses a keyway for positive mechanical engagement with pulleys or couplings, and the fitted shaft seal helps protect the interior against oil splash during operation.
