Product Description:

The MDD090A-N-040-N2L-130GL1 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it serves as the rotary actuating element in automated packaging lines, pick-and-place modules, and other precision positioning tasks. The unit couples directly to an Indramat drive, converting commanded current vectors into tightly controlled torque that can accelerate, decelerate, or hold machine elements with repeatable accuracy.

At a nominal speed of 4000 rpm, the rotor reaches application velocity without losing synchronism with the drive output frequency. During standstill, it can produce 3.7 Nm of continuous torque, enabling the axis to resist moderate process loads until motion resumes. The integrated blocking brake supplements this by delivering 6.5 Nm of static holding torque whenever the control issues a brake command or after power loss. Accurate mechanical centering is provided by the 130 mm flange shoulder, which aligns the motor concentrically on the machine frame. Position and speed information are transmitted through digital servo feedback, allowing the controller to close the velocity and position loops with high resolution.

Standard dynamic balancing limits residual vibration and helps protect upstream bearings during operation. The power and feedback plugs face the left side of the standard housing, and the single connector keeps cable routing compact at the motor interface. Size code 090 indicates the stator diameter, while length code A keeps the housing short for compact machines. A factory-installed shaft seal guards the internal bearings against coolant and dust ingress, and the output end uses a plain shaft with no side B shaft extension, allowing clamp or collet couplings without keyway stress.
