Product Description:

The MDD090B-N-040-N2L-130PA0 is a brushless synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to work with digital drive controllers, it converts commanded current into precise rotational motion for positioning, indexing, and speed-controlled tasks in automated equipment. The motor is intended for axes that require repeatable motion, stable torque response, and compact installation within machine frames.

In mechanical terms, the motor mounts against a centering flange that measures 130 mm, providing accurate alignment with gearboxes or machine frames. Its continuous torque at standstill is rated at 7.2 Nm, so the drive can hold and accelerate loads without overheating during dwell periods. The rotor can reach a nominal speed of 4000 rpm, allowing rapid indexing where high cycle rates are required. Power and feedback conductors exit on side A, which can simplify cable routing when the motor face is embedded in a machine wall. A connector couples the cabling instead of a hard-wired entry, and standard balancing helps limit vibration during rotation. The unit is supplied without a blocking brake, which keeps the motor shorter and reduces added inertia on the shaft.

Position information is transmitted through digital servo feedback, enabling the controller to maintain accurate velocity and torque regulation during motion. The output shaft uses a keyway so torque can be transferred to pulleys or couplings with minimal slip under load. A factory-installed shaft seal sits behind the front bearing, helping keep lubricant in and dust or coolant out during normal industrial cleaning. Frame classification 090 indicates the exterior diameter and bolt circle, while length code B gives the motor a medium body size that supports a balance of thermal capacity and compact depth. This arrangement fits multi-axis machinery where mounting space is limited but dependable servo performance is still required.
