Product Description:

The MDD090B-N-030-N2M-110GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current from an inverter into precise rotary motion within automated machines. Its permanent-magnet rotor and closed-loop feedback support coordinated axis movement in packaging lines, pick-and-place stations, and other positioning tasks that require repeatable speed and torque. This makes the unit suitable for applications where stable response and accurate positioning are important during frequent starts, stops, and directional changes.

It supplies a continuous standstill torque of 7.2 Nm, enabling the axis to hold process loads without overheating when motion is paused. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, which suits drive controller output frequencies used in indexing machinery. A spring-applied brake provides 6.5 Nm of static holding torque, so vertical or suspended loads remain secured during loss of input power. Mechanical alignment is supported by a centering pilot of 110 mm, which helps position the flange accurately against gearboxes or machine fixtures. Command accuracy is improved through digital servo feedback, which sends high-resolution position data to the controller for closed-loop speed and position control. The motor also uses standard dynamic balancing, a B-length frame, and size 090 laminations.

Connection hardware uses a Connector, allowing power and feedback leads to terminate in a compact plug-in interface. The output uses a Plain shaft, so torque is transmitted through friction couplings rather than a keyed joint. Motion data is generated by an Integrated multiturn absolute encoder, allowing position tracking across multiple revolutions even when input power is off. Because the cable exit is on the Right, routing can be arranged without sharp bends in cabinets that favor that side. The motor also includes a shaft seal and a blocking brake, and the shaft end remains standard without a side-B extension.
