Product Description:

The MDD090A-N-040-N2L-110PL0 is a synchronous servo motor built by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. In integrated machining cells, pick-and-place modules, and packaging lines, the unit converts regulated current from the controller into controlled mechanical rotation. This allows axis positions to be commanded with repeatable accuracy during indexing, feeding, and other coordinated motion tasks. The motor is intended for servo axes that rely on closed-loop control rather than fixed-speed operation.

At standstill, the motor can deliver a continuous torque of 3.7 Nm, allowing it to hold moderate loads without overheating when motion is paused. Its rated speed of 4000 rpm gives the axis a high operating speed under nominal conditions. A centering shoulder of 110 mm helps align the housing precisely on the machine frame and reduces lateral runout during installation. The output shaft uses a keyway, which provides a positive mechanical drive connection for couplings and pulleys. Position and velocity are returned to the controller through digital servo feedback, allowing real-time correction of current and motion.

All electrical terminations exit on the left side, and the supply uses a compact connector for straightforward cable routing in multi-axis cabinets. The motor is supplied without a blocking brake, so static holding torque must come from the drive or an external clamp when the axis is stopped. A contact-type shaft seal helps limit dust and spray ingress along the output shaft to support protected machine installations. The motor uses frame size 090 in the A length, which matches the mounting pattern for this housing class. Standard rotor balancing and the cast-iron housing support stable operation under typical industrial vibration and shock.
