Product Description:

The MDD090A-N-040-N2L-110PR2 is a compact AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies closed-loop rotary motion for indexing tables, pick-and-place axes, and other tightly coordinated automation tasks. The unit’s standard housing, standard balancing, and A-length frame support installation in modular machine layouts. Its compact form is well suited to machines that need accurate motion control without requiring a long motor body.

This model provides a continuous stall torque of 3.7 Nm, giving stable force output whenever the shaft must remain energized but stationary. During operation it reaches a nominal speed of 4000 rpm, a rating suited to medium-inertia loads driven by digital amplifiers. Mounting is guided by a centering shoulder of 110 mm, which helps align the motor concentrically with gearboxes or flanges. Power and feedback lines terminate through a connector, which allows quick connection during installation. Mechanical power is delivered through a shaft with a keyway, allowing positive coupling with pulleys or flexible couplings while helping prevent slippage under cyclic torque.

An integrated blocking brake supplies 11.0 Nm of holding torque, securing vertical axes when power is removed. The position loop uses digital servo feedback, so motor angle information is returned directly to the controller. All electrical terminations emerge on the right side of the housing, which can simplify cable routing when several axes are installed in parallel. A dedicated shaft seal limits ingress at the output end and helps protect internal areas during operation. The single-ended shaft layout leaves the rear end without an extension, which can reduce overhung load and leave more room around nearby machine components.
